NETL: Ambient Monitoring - Steubenville Comprehensive Air Monitoring  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Steubenville Comprehensive Air Monitoring Project (SCAMP) Steubenville Comprehensive Air Monitoring Project (SCAMP) The National Ambient Air Quality Standards for airborne fine particles (PM2.5) are based on the mass of PM2.5 measured at outdoor monitoring stations; however, most people spend the majority of their time indoors. In order to fully understand the relationship between ambient PM2.5 and human health effects, it is important to define how ambient PM2.5 concentrations and compositions compare to those actually breathed by humans during normal daily activities. The objective of SCAMP is to measure the concentrations of PM2.5 and other potential air pollutants at ambient monitoring stations in and around Steubenville, OH, and relate them to the pollutant concentrations in air that is actually breathed by people living in the area. Steubenville was chosen by DOE for this study because of the ability to integrate its results with those of the UORVP, and also because Steubenville was one of the six cities where correlations between ambient PM2.5 mass and adverse health effects had been noted. These correlations had been cited by EPA as one of the primary justifications for its 1997 ambient PM2.5 standards. Complete characterization of the relationships between ambient PM2.5 and human exposure, including the chemical components of PM2.5 at various locations, will provide a comprehensive database for use in subsequent epidemiological studies, long-range transport studies, and State Implementation Program development. CONSOL Energy is the primary performer of SCAMP, and will provide the necessary coordination and data integration between the various components of the study.

Database and Analytical Tool for Air Quality in the Upper Ohio River Valley Database and Analytical Tool for Air Quality in the Upper Ohio River Valley Advanced Technology Systems, Inc. with Ohio University and Texas A&M University - Kingsville as subcontractors, will develop a state-of-the-art, scalable and robust computer application for NETL to manage the extensive data sets resulting from the DOE-sponsored ambient air monitoring programs in the upper Ohio River valley region. Efforts will be made to include, to the greatest extent possible, ambient air data collected by other agencies in the upper Ohio River valley region, such as U.S. EPA, Pennsylvania Department of Environmental Protection (PA-DEP), West Virginia Division of Environmental Protection (WV-DEP), Ohio EPA, and the Allegheny County Health Department (ACHD). Although emphasis will be placed on data collected in the upper Ohio River valley region, the computer application developed under this Agreement will be designed, to the greatest extent possible, to access data collected at NETL-sponsored ambient air monitoring sites outside the region, such as sites operated by the Tennessee Valley Authority in the Great Smoky Mountains (under DOE Interagency Agreement DE-AI26-98FT40406) and by Southern Research Institute in North Birmingham, AL (under DOE Cooperative Agreement DE-FC26-00NT40770). The data base and analytical tool development effort will also be coordinated, to the greatest extent possible, with similar tools being developed for use by U.S. EPA. This will ensure that the database and analytical tools produced under this Agreement will be readily accessible to a wide variety of stakeholders.

Ambient air monitoring for organic compounds, acids, and metals at Los Alamos National Laboratory, January 1991  

SciTech Connect (OSTI)

Los Alamos National Laboratory (LANL) contracted Radian Corporation (Radian) to conduct a short-term, intensive air monitoring program whose goal was to estimate the impact of chemical emissions from LANL on the ambient air environment. A comprehensive emission inventory had identified more than 600 potential air contaminants in LANL's emissions. A subset of specific target chemicals was selected for monitoring: 20 organic vapors, 6 metals and 5 inorganic acid vapors. These were measured at 5 ground level sampling sites around LANL over seven consecutive days in January 1991. The sampling and analytical strategy used a combination of EPA and NIOSH methods modified for ambient air applications.

Nonradioactive Ambient Air Monitoring at Los Alamos National Laboratory 2001--2002  

SciTech Connect (OSTI)

During the spring of 2000, the Cerro Grande forest fire reached Los Alamos National Laboratory (LANL) and ignited both above-ground vegetation and disposed materials in several landfills. During and after the fire, there was concern about the potential human health impacts from chemicals emitted by the combustion of these Laboratory materials. Consequently, short-term, intensive air-monitoring studies were performed during and shortly after the fire. Unlike the radiological data from many years of AIRNET sampling, LANL did not have an adequate database of nonradiological species under baseline conditions with which to compare data collected during the fire. Therefore, during 2001 the Meteorology and Air Quality Group designed and implemented a new air-monitoring program, entitled NonRadNET, to provide nonradiological background data under normal conditions. The objectives of NonRadNET were to: (1) develop the capability for collecting nonradiological air-monitoring data, (2) conduct monitoring to develop a database of typical background levels of selected nonradiological species in the communities nearest the Laboratory, and (3) determine LANL's potential contribution to nonradiological air pollution in the surrounding communities. NonRadNET ended in late December 2002 with five quarters of data. The purpose of this paper is to organize and describe the NonRadNET data collected over 2001-2002 to use as baseline data, either for monitoring during a fire, some other abnormal event, or routine use. To achieve that purpose, in this paper we will: (1) document the NonRadNET program procedures, methods, and quality management, (2) describe the usual origins and uses of the species measured, (3) compare the species measured to LANL and other area emissions, (4) present the five quarters of data, (5) compare the data to known typical environmental values, and (6) evaluate the data against exposure standards.

Quantitative Assessment of Detection Frequency for the INL Ambient Air Monitoring Network  

SciTech Connect (OSTI)

A quantitative assessment of the Idaho National Laboratory (INL) air monitoring network was performed using frequency of detection as the performance metric. The INL air monitoring network consists of 37 low-volume air samplers in 31 different locations. Twenty of the samplers are located on INL (onsite) and 17 are located off INL (offsite). Detection frequencies were calculated using both BEA and ESER laboratory minimum detectable activity (MDA) levels. The CALPUFF Lagrangian puff dispersion model, coupled with 1 year of meteorological data, was used to calculate time-integrated concentrations at sampler locations for a 1-hour release of unit activity (1 Ci) for every hour of the year. The unit-activity time-integrated concentration (TICu) values were calculated at all samplers for releases from eight INL facilities. The TICu values were then scaled and integrated for a given release quantity and release duration. All facilities modeled a ground-level release emanating either from the center of the facility or at a point where significant emissions are possible. In addition to ground-level releases, three existing stacks at the Advanced Test Reactor Complex, Idaho Nuclear Technology and Engineering Center, and Material and Fuels Complex were also modeled. Meteorological data from the 35 stations comprising the INL Mesonet network, data from the Idaho Falls Regional airport, upper air data from the Boise airport, and three-dimensional gridded data from the weather research forecasting model were used for modeling. Three representative radionuclides identified as key radionuclides in INL’s annual National Emission Standards for Hazardous Air Pollutants evaluations were considered for the frequency of detection analysis: Cs-137 (beta-gamma emitter), Pu-239 (alpha emitter), and Sr-90 (beta emitter). Source-specific release quantities were calculated for each radionuclide, such that the maximum inhalation dose at any publicly accessible sampler or the National Emission Standards for Hazardous Air Pollutants maximum exposed individual location (i.e., Frenchman’s Cabin) was no more than 0.1 mrem yr–1 (i.e., 1% of the 10 mrem yr–1 standard). Detection frequencies were calculated separately for the onsite and offsite monitoring network. As expected, detection frequencies were generally less for the offsite sampling network compared to the onsite network. Overall, the monitoring network is very effective at detecting the potential releases of Cs-137 or Sr-90 from all sources/facilities using either the ESER or BEA MDAs. The network was less effective at detecting releases of Pu-239. Maximum detection frequencies for Pu-239 using ESER MDAs ranged from 27.4 to 100% for onsite samplers and 3 to 80% for offsite samplers. Using BEA MDAs, the maximum detection frequencies for Pu-239 ranged from 2.1 to 100% for onsite samplers and 0 to 5.9% for offsite samplers. The only release that was not detected by any of the samplers under any conditions was a release of Pu-239 from the Idaho Nuclear Technology and Engineering Center main stack (CPP-708). The methodology described in this report could be used to improve sampler placement and detection frequency, provided clear performance objectives are defined.

Ambient Operation of Li/Air Batteries  

SciTech Connect (OSTI)

In this work, Li/air batteries based on nonaqueous electrolytes were investigated in ambient conditions (with an oxygen partial pressure of 0.21 atm and relative humidity of ~20%). A heat-sealable polymer membrane was used as both an oxygen-diffusion membrane and as a moisture barrier for Li/air batteries. The membrane also can minimize the evaporation of the electrolyte from the batteries. Li/air batteries with this membrane can operate in ambient conditions for more than one month with a specific energy of 362 Wh kg-1, based on the total weight of the battery including its packaging. Among various carbon sources used in this work, Li/air batteries using Ketjenblack (KB) carbon-based air electrodes exhibited the highest specific energy. However, KB-based air electrodes expanded significantly and absorbed much more electrolyte than electrodes made from other carbon sources. The weight distribution of a typical Li/air battery using the KB-based air electrode was dominated by the electrolyte (~70%). Lithium-metal anodes and KB-carbon anodes account for only 5.12% and 5.78% of the battery weight, respectively. We also found that only ~ 20% of the mesopore volume of the air electrode was occupied by reaction products after discharge. To further improve the specific energy of the Li/air batteries, the microstructure of the carbon electrode needs to be further improved to absorb much less electrolyte while still holding significant amounts of reaction products

Solar Powered Radioactive Air Monitoring Stations  

SciTech Connect (OSTI)

Environmental monitoring of ambient air for radioactive material is required as stipulated in the PNNL Site radioactive air license. Sampling ambient air at identified preferred locations could not be initially accomplished because utilities were not readily available. Therefore, solar powered environmental monitoring systems were considered as a possible option. PNNL purchased two 24-V DC solar powered environmental monitoring systems which consisted of solar panels, battery banks, and sampling units. During an approximate four month performance evaluation period, the solar stations operated satisfactorily at an on-site test location. They were subsequently relocated to their preferred locations in June 2012 where they continue to function adequately under the conditions found in Richland, Washington.

Characterization of ambient air pollution for stochastic health models  

SciTech Connect (OSTI)

This research is an analysis of various measures of ambient air pollution useful in cross-sectional epidemiological investigations and rick assessments. The Chestnut Ridge area health effects investigation, which includes a cross-sectional study of respiratory symptoms in young children, is used as a case study. Four large coal-fired electric generating power plants are the dominant pollution sources in this area of western Pennsylvania. The air pollution data base includes four years of sulfur dioxide and five years of total suspended particulate concentrations at seventeen monitors. Some 70 different characterizations of pollution are constructed and tested. These include pollutant concentrations at various percentiles and averaging times, exceedence measures which show the amount of time a specified threshold concentration is exceeded, and several dosage measures which transform non-linear dose-response relationships onto pollutant concentrations.

Southern Fine Particulate Monitoring Project (SRI) Southern Fine Particulate Monitoring Project (SRI) Southern Research Institute (SRI), Birmingham, AL, is operating a research station in North Birmingham for monitoring fine particulate matter (PM2.5) that exists in that part of the Deep South. The station will be a core PM2.5 mass monitoring and chemical speciation station in the nationwide EPA PM2.5 network. As such, it will be a complement and supplement to DOE-NETL's other ongoing projects for monitoring fine particulate matter in the upper Ohio River valley. Locating additional monitoring equipment in the Deep South will fill an important gap in the national particulate monitoring effort. The region's topography, weather patterns, and variety of emission sources may affect the chemical make-up and airborne transport of fine particles in ways that are different than in other parts of the country. The project's results will support DOE's comprehensive program to evaluate ambient fine particulate matter through better understanding of the chemical and physical properties of these materials.

SciTech Connect (OSTI)

As part of a program to characterize and baseline selected environmental parameters in the region around the proposed repository at Yucca Mountain, Nevada, ambient radon-222 monitoring was conducted in the rural community of Amargosa Valley, the community closest to the proposed repository site. Passive integrating radon monitors and a continuous radon monitoring instrument were deployed adjacent to the Community Environmental Monitoring Program (CEMP) (http://www.cemp.dri.edu/index.html) station located in the Amargosa Valley Community Center near the library. The CEMP station provided real-time ambient gamma exposure and meteorological data used to correct the integrated radon measurements as well as verify meteorological data collected by the continuous radon monitoring instrument. Additionally, different types of environmental enclosures that housed the monitors and instrument were used to determine if particular designs influenced the ambient radon measurements.

Ambient air VOC concentrations at WIPP  

SciTech Connect (OSTI)

The Waste Isolation Pilot Plant (WIPP), located near Carlsbad, New Mexico, is an underground facility designated as a potential repository for transuranic wastes. Approximately 60% of the wastes proposed to be emplaced at the WIPP are considered mixed wastes, which contain both radioactive and Resource Conservation and Recovery Act-regulated hazardous chemical components. As part of the Addendum to the WIPP No-Migration Variance Petition', the US Department of Energy presented a plan to monitor the release of volatile organic compounds (VOCs) from the WIPP unit boundary. This program should fulfill the monitoring requirements of 40CFR268.6 allowing the disposal of wastes prohibited from land disposal only after demonstration that, to a reasonable degree of certainty, there will be no migration of constituents from the disposal unit for as long as the wastes remain hazardous.

NETL: Ambient Monitoring - Contribution of Semi-volatile Organic Material  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Semi-volatile Organics in PM Semi-volatile Organics in PM This project is a cooperative effort between Brigham Young University (BYU) and researchers from the DOE-NETL Office of Science and and Engineering Research to determine the contribution of semi-volatile particulate organic compounds (SVOC) to total ambient suspended fine particulate mass at the NETL-Pittsburgh air monitoring facility. Project funding comes from DOE‘s University Coal Research (UCR) program. The hypothesis of the project is that fine particulate mass will be significantly under-determined in urban environments using single filter samplers such as the PM2.5 Federal Reference Method (FRM) because of the loss of semi-volatile organic compounds (SVOC) from the particles during sampling and storage. It is postulated that fine particulate mass, including the semi-volatile fine particulate organic species, are an appropriate surrogate for the components of fine particles which are associated with observed mortality and morbidity effects in epidemiological studies. Further, it is postulated that the most important fraction of the semi-volatile organic material with respect to exacerbation of health problems will be semi-volatile secondary compounds formed from reactions of volatile organic material with ozone and nitrogen oxides. Under-determination of these semi-volatile species will tend to over emphasize the importance of non-volatile fine particulate components such as sulfate or may reduce the significance of correlations with measured health effects.

The Perkin-Elmer ATD-400 system for monitoring of ambient VOC ozone precursors  

SciTech Connect (OSTI)

The systems described were used in the Texas Natural Resource Conservation Commission (TNRCC) Coastal Oxidant Assessment for Southeast Texas (COAST) program. Continuous VOC monitoring programs were implemented in June through November of this year in Houston. This Perkin-Elmer developed monitoring system included a dual capillary column chromatographic application in an 8700 GC with a modified ATD-400 sampling system. The resulting separations are monitored and quantified using Turbochrom (ver. 3.2) chromatographic data handling software. The key element to this system is the thermal desorption device which is capable of concentrating VOCs from ambient air then desorbing them directly to the gas chromatograph on a continuous cycle.The ATD-400, unlike other similar devices, contains an activated carbon trap which is electrically cooled during collection via Peltier technology. This eliminates the need for cryogenic liquids or compressed air (vortex) for sample collection and makes unattended field operation more feasible than previous systems. The entire system is integrated to provide a completely automatic sample collection cycle, gas chromatographic analysis and data collection, reduction and report generation. Reliability and repeatability data suggest that the system is robust. Good correlation between systems and quality audits confirms data from the manufacturer. Modifications which are being implemented to the chromatographic system, system sites, and operator behavior to enhance the system performance will also be presented.

Technical comments on EPA`s proposed revisions to the National Ambient Air Quality Standard for particulate matter  

SciTech Connect (OSTI)

The US Environmental Protection Agency (EPA) has proposed new ambient air quality standards specifically for fine particulate matter, regulating concentrations of particles with median aerodynamic diameters less than 2.5 {mu}m (PM{sub 2.5}). Two new standards have been proposed: a maximum 24-hr concentration that is intended to protect against acute health effects, and an annual concentration limit that is intended to protect against longer-term health effects. EPA has also proposed a slight relaxation of the 24-hr standard for inhalable particles (PM{sub 10}), by allowing additional exceedances each year. Fine particles are currently being indirectly controlled by means of regulations for PM{sub 10} and TSP, under the Clean Air Act of 1970 and subsequent amendments. Although routine monitoring of PM{sub 2.5} is rare and data are sparse, the available data indicate that ambient concentrations have been declining at about 6% per year under existing regulations.

Upper Ohio River Valley Project Upper Ohio River Valley Project In cooperation with key stakeholders including EPA, local and state environmental agencies, industry, and academia, the U.S. Department of Energy (DOE) has established the Upper Ohio River Valley Project (UORVP), a network for monitoring and characterizing PM2.5 in the Upper Ohio River Valley. This region was chosen because it has a high density of coal-fired electric utilities, heavy industries (e.g. coke and steel making), light industry, and transportation emission sources. It is also ideally situated to serve as a platform for the study of interstate pollution transport issues. This region, with its unique topography (hills and river valleys) as well as a good mix of urban and rural areas, has a high population of elderly who are susceptible to health impacts of fine particulate as well as other related environmental issues (e.g., acid rain, Hg deposition, ozone). A world-class medical research/university system is also located in the region, which will facilitate the subsequent use of the air quality data in studies of PM2.5 health effects.

Continuous Air Monitor Operating Experience Review  

SciTech Connect (OSTI)

Continuous air monitors (CAMs) are used to sense radioactive particulates in room air of nuclear facilities. CAMs alert personnel of potential inhalation exposures to radionuclides and can also actuate room ventilation isolation for public and environmental protection. This paper presents the results of a CAM operating experience review of the DOE Occurrence Reporting and Processing System (ORPS) database from the past 18 years. Regulations regarding these monitors are briefly reviewed. CAM location selection and operation are briefly discussed. Operating experiences reported by the U.S. Department of Energy and in other literature sources were reviewed to determine the strengths and weaknesses of these monitors. Power losses, human errors, and mechanical issues cause the majority of failures. The average “all modes” failure rate is 2.65E-05/hr. Repair time estimates vary from an average repair time of 9 hours (with spare parts on hand) to 252 hours (without spare parts on hand). These data should support the use of CAMs in any nuclear facility, including the National Ignition Facility and the international ITER experiment.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Characterization of Ambient PM2.5 in the Upper Midwest Characterization of Ambient PM2.5 in the Upper Midwest As part of a Cooperative Agreement with DOE-NETL, the University of North Dakota Energy and Environmental Research Center (EERC) is developing advanced sampling and analysis methodologies for particulate matter that can be used for source apportionment and to assist in health studies. These techniques will be used to determine sources of fine particulate matter in rural states such as North Dakota. Ambient particulate matter (PM) sampling and automated scanning electron microscopy, (ASEM) are being used to characterize and evaluate the sources of PM2.5 at three rural sites. Land use in the sampling site locations is dominated by ranching and small grain farming. Potential sources of PM in these areas include diesel- and gasoline-fueled motor vehicles, fugitive dust from gravel roads and agriculture, vegetation and fires, an oil refinery, and coal-fired power plants. PM2.5 samples were collected using an automatic cartridge collection unit for ASEM analysis. An ASEM method has been developed to size and chemically classify individual particles composing PM2.5.

Influences of ambient air speed and internal heat load on the performance of solar chimney in the tropics  

Science Journals Connector (OSTI)

Abstract Solar chimney is a combination of solar assisted stack and wind driven ventilation where air in the solar chimney expands under heating from solar irradiance and being relatively lighter, rises out from the chimney outlets, drawing the cooler air into the building through the fenestrations. This pull effect is complemented further by the push effect from the outdoor ambient wind. The study of solar chimney system within the zero energy building in tropical Singapore aims to determine the effects of ambient air speed and internal heat load on the thermal environment of the solar chimney ducts and classroom’s interior. Experimental and computational results show that high ambient air speed greater than 2.00 m/s improves the air speed within the solar chimney ducts; both low and high ambient air speeds are found to improve the classroom’s interior air speed. However, the significance of ambient air speed drops when solar irradiance is greater than 700 W/m2. Furthermore, under the tropical weather conditions of high solar irradiance and low ambient air speed, cross ventilation performs better compared to solar chimney; hence, solar chimney is recommended to be employed under zero ambient air speed. Lastly, results show that the influences of internal heat load on the air temperature and speed within solar chimney ducts as well as classroom’s interior are limited.

Ambient air pollution exposure and the incidence of related health effects among racial/ethnic minorities  

SciTech Connect (OSTI)

Differences among racial and ethnic groups in morbidity and mortality rates for diseases, including diseases with environmental causes, have been extensively documented. However, documenting the linkages between environmental contaminants, individual exposures, and disease incidence has been hindered by difficulties in measuring exposure for the population in general and for minority populations in particular. After briefly discussing research findings on associations of common air pollutants with disease incidence, the authors summarize recent studies of radial/ethnic subgroup differences in incidence of these diseases in the US. They then present evidence of both historic and current patterns of disproportionate minority group exposure to air pollution as measured by residence in areas where ambient air quality standards are violated. The current indications of disproportionate potential exposures of minority and low-income populations to air pollutants represent the continuation of a historical trend. The evidence of linkage between disproportionate exposure to air pollution of racial/ethnic minorities and low-income groups and their higher rates of some air pollution-related diseases is largely circumstantial. Differences in disease incidence and mortality rates among racial/ethnic groups are discussed for respiratory diseases, cancers, and lead poisoning. Pollutants of concern include CO, Pb, SO{sub 2}, O{sub 3}, and particulates.

Industrial CO2 Removal: CO2 Capture from Ambient Air and Geological Sequestration  

SciTech Connect (OSTI)

This abstract and its accompanying presentation will provide an overview of two distinct industrial processes for removing carbon dioxide (CO2) from the atmosphere as a means of addressing anthropogenic climate change. The first of these is carbon dioxide capture and storage (CCS) coupled with large scale biomass production (hereafter referred to as bioCCS). The second is CO2 capture from ambient air via industrial systems (hereafter referred to as direct air capture (DAC)). In both systems, the captured CO2 would be injected into deep geologic formations so as to isolate it from the atmosphere. The technical literature is clear that both of these technologies are technically feasible as of today (IPCC, 2005; Keith, 2009; Lackner, 2009; Luckow et al., 2010; Ranjan and Herzog, 2011). What is uncertain is the relative cost of these industrial ambient-air CO2 removal systems when compared to other emissions mitigation measures, the ultimate timing and scale of their deployment, and the resolution of potential site specific constraints that would impact their ultimate commercial deployment.

This report has been prepared to make available and archive background scientific data and related information on climate, ambient air quality, and ambient noise levels collected during the preparation of the environmental impact statement (EIS) for Phases 3 and 4 of the Hawaii Geothermal Project (HGP) as defined by the state of hawaii in its April 1989 proposal to Congress. The US Department of Energy (DOE) published a notice in the Federal Register on May 17, 1994 withdrawing its Notice of Intent of February 14, 1992, to prepare the HGP-EIS. Since the state of Hawaii is no longer pursuing or planning to pursue the HGP, DOE considers the project to be terminated. The report presents a general description of the climate and air quality for the islands of Hawaii (henceforth referred to as Hawaii), Maui, and Oahu. It also presents a literature review as baseline information on the health effects of hydrogen sulfide. the scientific background data and related information is being made available for use by others in conducting future scientific research in these areas. This report describes the environmental resources present in the areas studied (i.e., the affected environment) and does not represent an assessment of environmental impacts.

Air Monitoring of Emissions from the Fukushima Daiichi Reactor  

SciTech Connect (OSTI)

In response to the disasters in Japan on March 11, 2011, and the subsequent emissions from Fukushima-Daiichi, we monitored the air near Los Alamos using four air-monitoring systems: the standard AIRNET samplers, the standard rad-NESHAP samplers, the NEWNET system, and high-volume air samplers. Each of these systems has advantages and disadvantages. In combination, they provide a comprehensive set of measurements of airborne radionuclides near Los Alamos during the weeks following March 11. We report air-monitoring measurements of the fission products released from the Fukushima-Daiichi nuclear-power-plant accident in 2011. Clear gamma-spectrometry peaks were observed from Cs-134, Cs-136, Cs-137, I-131, I132, Te-132, and Te-129m. These data, together with measurements of other radionuclides, are adequate for an assessment and assure us that radionuclides from Fukushima Daiichi did not present a threat to human health at or near Los Alamos. The data demonstrate the capabilities of the Los Alamos air-monitoring systems.

Tonopah Test Range Air Monitoring: CY2013 Meteorological, Radiological, and Airborne Particulate Observations  

SciTech Connect (OSTI)

In 1963, the U.S. Department of Energy (DOE) (formerly the Atomic Energy Commission [AEC]), implemented Operation Roller Coaster on the Tonopah Test Range (TTR) and an adjacent area of the Nevada Test and Training Range (NTTR) (formerly the Nellis Air Force Range). This test resulted in radionuclide-contaminated soils at Clean Slate I, II, and III. This report documents observations made during on-going monitoring of radiological, meteorological, and dust conditions at stations installed adjacent to Clean Slate I and Clean Slate III and at the TTR Range Operations Control center. The primary objective of the monitoring effort is to determine if winds blowing across the Clean Slate sites are transporting particles of radionuclide-contaminated soils beyond both the physical and administrative boundaries of the sites. Results for the calendar year (CY) 2013 monitoring include: (1) the gross alpha and gross beta values from the monitoring stations are approximately equivalent to the highest values observed during the CY2012 reporting at the surrounding Community Environmental Monitoring Program (CEMP) stations (this was the latest documented data available at the time of this writing); (2) only naturally occurring radionuclides were identified in the gamma spectral analyses; (3) the ambient gamma radiation measurements indicate that the average annual gamma exposure is similar at all three monitoring stations and periodic intervals of increased gamma values appear to be associated with storm fronts passing through the area; and (4) the concentrations of both resuspended dust and saltated sand particles generally increase with increasing wind speed. However, differences in the observed dust concentrations are likely due to differences in the soil characteristics immediately adjacent to the monitoring stations. Neither the resuspended particulate radiological analyses nor the ambient gamma radiation measurements suggest wind transport of radionuclide-contaminated soils.

ENHANCEMENT OF ENVIRONMENTAL SAMPLING THROUGH AN IMPROVED AIR MONITORING TECHNIQUE  

SciTech Connect (OSTI)

Environmental sampling (ES) is a key component of International Atomic Energy Agency (IAEA) safeguarding approaches throughout the world. Performance of ES (e.g. air, water, vegetation, sediments, soil and biota) supports the IAEAs mission of drawing conclusions concerning the absence of undeclared nuclear material or nuclear activities in a State and has been available since the introduction of safeguards strengthening measures approved by the IAEA Board of Governors (1992-1997). A recent step-change improvement in the gathering and analysis of air samples at uranium/plutonium bulk handling facilities is an important addition to the international nuclear safeguards inspector's toolkit. Utilizing commonly used equipment throughout the IAEA network of analytical laboratories for particle analysis, researchers are developing the next generation of ES equipment for air grab and constant samples. Isotopic analysis of collected particles from an Aerosol Contaminant Extractor (ACE) silicon substrate has been performed with excellent results in determining attribute and isotopic composition of chemical elements present in an actual test-bed sample. The new collection equipment will allow IAEA nuclear safeguards inspectors to develop enhanced safeguarding approaches for complicated facilities. This paper will explore the use of air monitoring to establish a baseline environmental signature of a particular facility that could be used for comparison of consistencies in declared operations. The implementation of air monitoring will be contrasted against the use of smear ES when used during unannounced inspections, design information verification, limited frequency unannounced access, and complementary access visits at bulk handling facilities. Technical aspects of the air monitoring device and the analysis of its environmental samples will demonstrate the essential parameters required for successful application of the system.

Protocols of radiocontaminant air monitoring for inhalation exposure estimates  

SciTech Connect (OSTI)

Monitoring the plutonium and americium particle emissions from soils contaminated during atmospheric nuclear testing or due to accidental releases is important for several reasons. First, it is important to quantify the extent of potential human exposure from inhalation of alpha-emitting particles, which is the major exposure pathway from transuranic radionuclides. Second, the information provided by resuspension monitoring is the basis of criteria that determine the target soil concentrations for management and cleanup of contaminated soil sites. There are other radioactive aerosols, such as the fission products (cesium and strontium) and neutron-activation products (europium isotopes), which may be resuspended and therefore necessary to monitor as well. This Standard Protocol (SP) provides the method used for radiocontaminant air monitoring by the Health and Ecological Assessment Division (formerly Environmental Sciences Division), Lawrence Livermore National Laboratory, as developed and tested at Nevada Test Site (NTS) and in the Marshall Islands. The objective of this SP is to document the applications and methods of monitoring of all the relevant variables. This protocol deals only with measuring air concentrations of radionuclides and total suspended particulates (TSP, or {open_quotes}dust{close_quotes}). A separate protocol presents the more difficult measurements required to determine transuranic aerosol emission rates, or {open_quotes}resuspension rate{close_quotes}.

Smart SCADA system for urban air pollution monitoring  

Science Journals Connector (OSTI)

Abstract There are a number of different types of monitoring stations for checking air quality levels in urban environments. These monitoring stations usually just perform data acquisition of the measured values from the sensors and store them in the database. The processing of the measured results as well as the statistical analysis is mainly done in other places where the data come from various communication systems. Acquisition of the measured data is commonly done on-line while the processing and statistical analysis is performed off-line. As opposed to these measurement systems, this implemented device enables the acquisition and statistical processing of the measured data in real time and the results are instantly available to all users. The system indicates the air pollutants using the ARMA model. The transmission of information in the realized smart SCADA system is done by the Modbus protocol using shared variables which gives the whole system a stronger hierarchical structure.

River Corridor Project Workplace Air Monitoring Technical Basis  

SciTech Connect (OSTI)

This document provides the technical basis by which the workplace air monitoring and sampling program is operated in the River Corridor Project (RCP). Revision 2 addresses and incorporates changes in the air monitoring program drivers and implementing documents which occurred after the previous revision was issued. This revision also includes an additional RCP project to make Revision 2 applicable to the entire RCP. These changes occurred in the following areas: (1) Changes resulting from the conversion of the Hanford Site Radiological Control Manual (HSRCM-1) into the Project Hanford Radiological Control Manual (F-5173). HNF-5173 is now the implementing document for 10CFR835. (2) Changes resulting from the issue of new and revised Hanford Site implementing procedures. (3) Changes resulting from the issue of new and revised, as well as the cancellation of RCP implementing procedures. (4) Addition of the 200 Area Accelerated Deactivation Project (ADP). (5) Modification of some air sampling/monitoring locations to better meet the needs of facility operations. (6) Changes resulting from the RCP reorganization.

Comparison of continuous air monitor utilization: A case study  

SciTech Connect (OSTI)

The Chemical Metallurgy Research (CMR) building has been upgrading to different continuous air monitors (CAMs) over the past several years. During the transition, both the newer and older CAMs were positioned in the rooms for field testing and comparison. On December 19, 1996, an accidental release of plutonium aerosol occurred into a laboratory in the CMR building. The event occurred while the room was unoccupied, and no personnel were exposed from this incident. There were two fixed air samplers (FASs) and three CAMs operating in the room at the time the release occurred, including two of the recently installed Canberra Alpha Sentry CAMs and one older Eberline CAM. The apparent cause of the release was a procedure carried out in the basement involving the replacement of the HEPA filter in the ventilation exhaust of a slot-box in the laboratory. For a short period, the ventilation was disconnected from the slot-box in this room, but not from the chemical hood exhaust on the opposite side of the laboratory. Therefore, a condition was created where backflow could occur out of the slot-box and into the room. Eventually all three CAMs in the room alarmed, and the situation was successfully monitored and brought under control by health physics personnel. Data on CAM performance were logged, and Pu activity collected on CAM and FAS filters were measured. A comparison of the new and old continuous air monitoring programs was performed and many interesting lessons on CAM performance and CAM utilization were learned. Overall, this comparison showed the advantages of remote monitoring, timely spectral information, and concentration measurements resolved in time and space.

Computation of structural flexibility for bridge health monitoring using ambient modal data  

SciTech Connect (OSTI)

Issues surrounding the use of ambient vibration modes for the location of structural damage via dynamically measured flexibility are examined. Several methods for obtaining the required mass- normalized dynamic mode shapes from ambient modal data are implemented and compared. The method are applied to data from a series of ambient modal tests on an actual highway bridge. Results indicate that for the damage case examined, the flexibility from the ambient mode shapes gave a better indication of damage than the flexibility from the forced-vibration mode shapes. This improved performance is attributed to the higher excitation load levels that occur during the ambient test.

Ultrahigh Sensitivity Heavy Noble Gas Detectors for Long-Term Monitoring and for Monitoring Air  

SciTech Connect (OSTI)

The primary objective of this research project is to develop heavy noble gas (krypton, xenon, and radon) detectors for (1) long-term monitoring of transuranic waste, spent fuel, and other uranium and thorium bearing wastes and (2) alpha particle air monitors that discriminate between radon emissions and other alpha emitters. A University of Cincinnati/Argonne National Laboratory (UC/ANL) Team was assembled to complete this detector development project. Effective 1/4/99, the UC PI (John Valentine) became an Associate Professor in the Nuclear and Radiological Engineering Program of the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. Consequently, this project was transferred to Georgia Tech (GT) with the PI. UC funding extended to 1/31/99 and GT funding became active 4/26/99. Due to this transfer, we will refer to the research team as the GT/UC/ANL Team for this Annual Report. Subsequently, we will use GT/ANL Team. DOE needs that are ad dressed by this project include improved long-term monitoring capability and improved air monitoring capability during remedial activities. Successful development and implementation of the proposed detection systems could significantly improve current capabilities with relatively simple and inexpensive equipment.

Continuous air monitor for alpha-emitting aerosol particles  

SciTech Connect (OSTI)

A new alpha Continuous Air Monitor (CAM) sampler is being developed for use in detecting the presence of alpha-emitting aerosol particles. The effort involves design, fabrication and evaluation of systems for the collection of aerosol and for the processing of data to speciate and quantify the alpha emitters of interest. At the present time we have a prototype of the aerosol sampling system and we have performed wind tunnel tests to characterize the performance of the device for different particle sizes, wind speeds, flow rates and internal design parameters. The results presented herein deal with the aerosol sampling aspects of the new CAM sampler. Work on the data processing, display and alarm functions is being done in parallel with the particle sampling work and will be reported separately at a later date. 17 refs., 5 figs., 3 tabs.

Air and rain toxics deposition monitoring in Galveston Bay Texas  

SciTech Connect (OSTI)

In order to fulfill the mandates of the Great Waters Program and portions of the Clean Air Act Amendments of 1990, the Environmental Protection Agency (EPA) has initiated atmospheric monitoring research in important and representative water bodies, including coastal waters, for evidence of atmospheric deposition of pollutants. These pollutants include nutrients, trace metals, polynuclear aromatic hydrocarbons and PCBs. A site was established in Seabrook Texas on the western shore of Galveston Bay representative of southern, coastal water system. This study determines selected environmental pollutants of potential concern to Galveston Bay and other Gulf coastal waters. While information is currently being generated by other investigations in Galveston Bay, such as EPA EMAP, Galveston Bay National Estuary, NOAA Status and Trends and other programs on contaminants in sediments and organisms, little reliable data is available to assess atmospheric deposition. The importance of atmospheric deposition of contaminants to Galveston Bay, based on air and rain samples collected continuously from March 1995 to March 1996 will be presented and compared to the results from other Great Waters Program sites. These results are critical to the understanding of the relative importance of various contaminant inputs to Galveston Bay by estimating atmospheric depositional fluxes.

Association between Ambient Air Pollution and Outpatient Visits for Acute Bronchitis in a Chinese City  

Science Journals Connector (OSTI)

AbstractObjective To investigate the short-term association between outdoor air pollution and outpatient visits for acute bronchitis, which is a rare subject of research in the mainland of China. Methods A time-series analysis was conducted to examine the association of outdoor air pollutants with hospital outpatient visits in Shanghai by using two-year daily data (2010-2011). Results Outdoor air pollution was found to be associated with an increased risk of outpatient visits for acute bronchitis in Shanghai. The effect estimates of air pollutants varied with the lag structures of the concentrations of the pollutants. For lag06, a 10 ?g/m3 increase in the concentrations of PM10, SO2, and NO2 corresponded to 0.94% (95% CI: 0.83%, 1.05%), 11.12% (95% CI: 10.76%, 11.48%), and 4.84% (95% CI: 4.49%, 5.18%) increases in hospital visits for acute bronchitis, respectively. These associations appeared to be stronger in females (Pair pollution level in China has an effect on acute bronchitis and that the rationale for further limiting air pollution levels in Shanghai should be strengthened.

Acute effect of ambient air pollution on heart failure in Guangzhou, China  

Science Journals Connector (OSTI)

AbstractBackground Heart failure (HF) is a global public health problem of increasing importance. The association between acute exposure to air pollution and HF has been well established in developed countries, but little evidence was available in developing countries where air pollution levels were much higher. We conducted a time-series study to investigate the short-term association between air pollution and overall emergency ambulance dispatches (EAD) due to HF in Guangzhou, China. Methods Daily data of EAD due to HF from 1 January 2008 to 31 December 2012 were obtained from Guangzhou Emergency Center. We applied the over-dispersed Poisson generalized addictive model to analyze the associations after controlling for the seasonality, day of the week and weather conditions. Results We identified a total of 3375 EAD for HF. A 10-?g/m3 increase in the present-day concentrations of particulate matter with an aerodynamic diameter of less than 10 ?m, sulfur dioxide and nitrogen dioxide corresponded to increases of 3.54% [95% confidence interval (CI): 1.35%, 5.74%], 5.29% (95% CI: 2.28%, 8.30%) and 4.34% (95% CI: 1.71%, 6.97%) in daily EAD for HF, respectively. The effects of air pollution on acute HF were restricted on the concurrent day and in the cool seasons. Conclusions Our results provided the first population-based evidence in Mainland China that outdoor air pollution could trigger the exacerbation of HF.

Localized DLC etching by a non-thermal atmospheric-pressure helium plasma jet in ambient air  

Science Journals Connector (OSTI)

Abstract Using a versatile atmospheric-pressure helium plasma jet, diamond-like carbon (DLC) films were etched in ambient air. We observed that the DLC films are etched at a nominal rate of around 60 nm/min in the treated area (230 ?m in diameter) during a 20-min exposure. The etching rate increased after the initial 10-min exposure. During this period, the flat DLC surface was structurally modified to produce carbon nanostructures with a density of ~ 2.4 × 1011 cm? 2. With this increase in surface area, the etching rate increased. After 20 min, the DLC film had a circular pattern etched into it down to the substrate where silicon nanostructures were observed with sizes varying from 10 nm to 1 ?m. The initial carbon nanostructure formation is believed to involve selective removal of the sp2-bonded carbon domains. The carbon etching results from the formation of reactive oxygen species in the plasma.

COMPARATIVE EVALUATION OF AMBIENT FINE PARTICULATE MATTER (PM2.5)DATA OBTAINED FROM URBAN AND RURAL MONITORING SITES ALONG THE UPPER OHIO RIVER VALLEY  

SciTech Connect (OSTI)

Advanced Technology Systems, Inc. (ATS), with Desert Research Institute (DRI) and Ohio University as subcontractors, was contracted by the NETL in September 1998 to manage the Upper Ohio River Valley Project (UORVP), with a goal of characterizing the ambient fine particulate in this region, including examination of urban/rural variations, correlations between PM{sub 2.5} and gaseous pollutants, and influences of artifacts on PM{sub 2.5} measurements in this region. Two urban and two rural monitoring sites were included in the UORVP. The four sites selected were all part of existing local and/or state air quality programs. One urban site was located in the Lawrenceville section of Pittsburgh, Pennsylvania at an air quality monitoring station operated by the Allegheny County Health Department. A second urban site was collocated at a West Virginia Division of Environmental Protection (WVDEP) monitoring station at the airport in Morgantown, West Virginia. One rural site was collocated with the Pennsylvania Department of Environmental Protection (PADEP) at a former NARSTO-Northeast site near Holbrook, Greene County, Pennsylvania. The other rural site was collocated at a site operated by the Ohio Environmental Protection Agency (OHEPA) and managed by the Ohio State Forestry Division in Gifford State Forest near Athens, Ohio. Analysis of data collected to date show that: (1) the median mass and composition of PM{sub 2.5} are similar for both Lawrenceville and Holbrook, suggesting that the sites are impacted more by the regional than by local effects; (2) there was no significant differences in the particulate trending and levels observed at both sites within seasons; (3) sulfate levels predominate at both sites, and (4) PM{sub 2.5} and PM{sub 10} mass concentration levels are consistently higher in summer than in winter, with intermediate levels being observed in the fall and spring. Data analysis focusing on relating the aerometric measurements to local and regional scale emissions of sources of primary and secondary fine particles using receptor-based air quality models will follow.

Environmental radiological monitoring of air, rain, and snow on and near the Hanford Site, 1945-1957  

SciTech Connect (OSTI)

This report is a result of the Hanford Environmental Dose Reconstruction (HEDR) Project. The goal of the HEDR Project is to estimate the radiation dose that individuals could have received from emissions since 1944 at the Hanford Site near Richland, Washington. Members of the HEDR Project`s Environmental Monitoring Data Task have developed databases of historical environmental measurements of such emissions. Hanford documents were searched for information on the radiological monitoring of air, rain, and snow at and near the Hanford Site in Richland, Washington. The monitoring information was reviewed and summarized. The end product is a yearly overview of air, rain, and snow samples as well as ambient radiation levels in the air that were measured from 1945 through 1957. The following information is provided in each annual summary: the media sampled, the constituents (radionuclides) measured/reported, the sampling locations, the sampling frequencies, the sampling methods, and the document references. For some years a notes category is included that contains additional useful information. For the years 1948 through 1957, tables summarizing the sampling locations for the various sample media are also included in the appendix. A large number of documents were reviewed to obtain the information in this report. A reference list is attached to the end of each annual summary. All of the information summarized here was obtained from reports originating at Hanford. These reports are all publicly available and can be found in the Richland Operations Office (RL) public reading room. The information in this report has been compiled without analysis and should only be used as a guide to the original documents.

Lasing of ambient air with microjoule pulse energy pumped by a multi terawatt IR femtosecond laser  

E-Print Network [OSTI]

We report on the lasing action of atmospheric air pumped by an 800 nm femtosecond laser pulse with peak power up to 4 TW. Lasing emission at 428 nm increases rapidly over a small range of pump laser power, followed by saturation above ~ 1.5 TW. The maximum lasing pulse energy is measured to be 2.6 uJ corresponding to an emission power in the MW range, while a maximum conversion efficiency of is measured at moderate pump pulse energy. The optical gain inside the filament plasma is estimated to be excess of 0.7/cm. The lasing emission shows a doughnut profile, reflecting the spatial distribution of the pump-generated white-light continuum that acts as a seed for the lasing. We attribute the pronounced saturation to the defocusing of the seed in the plasma amplifying region and to the saturation of the seed intensity.

Comparing land use regression and dispersion modelling to assess residential exposure to ambient air pollution for epidemiological studies  

Science Journals Connector (OSTI)

AbstractBackground Land-use regression (LUR) and dispersion models (DM) are commonly used for estimating individual air pollution exposure in population studies. Few comparisons have however been made of the performance of these methods. Objectives Within the European Study of Cohorts for Air Pollution Effects (ESCAPE) we explored the differences between LUR and DM estimates for NO2, PM10 and PM2.5. Methods The ESCAPE study developed LUR models for outdoor air pollution levels based on a harmonised monitoring campaign. In thirteen ESCAPE study areas we further applied dispersion models. We compared LUR and DM estimates at the residential addresses of participants in 13 cohorts for NO2; 7 for PM10 and 4 for PM2.5. Additionally, we compared the DM estimates with measured concentrations at the 20–40 ESCAPE monitoring sites in each area. Results The median Pearson R (range) correlation coefficients between LUR and DM estimates for the annual average concentrations of NO2, PM10 and PM2.5 were 0.75 (0.19–0.89), 0.39 (0.23–0.66) and 0.29 (0.22–0.81) for 112,971 (13 study areas), 69,591 (7) and 28,519 (4) addresses respectively. The median Pearson R correlation coefficients (range) between DM estimates and ESCAPE measurements were of 0.74 (0.09–0.86) for NO2; 0.58 (0.36–0.88) for PM10 and 0.58 (0.39–0.66) for PM2.5. Conclusions LUR and dispersion model estimates correlated on average well for NO2 but only moderately for PM10 and PM2.5, with large variability across areas. DM predicted a moderate to large proportion of the measured variation for NO2 but less for PM10 and PM2.5.

Dynamic Control of Lab Air Change Rates using Multiplexed IEQ Monitoring Dynamic Control of Lab Air Change Rates using Multiplexed IEQ Monitoring Speaker(s): Gordon P. Sharp Date: October 14, 2005 - 12:00pm Location: Bldg. 90 Many aspects of a lab are monitored today in real time such as HVAC equipment operation and lab airflow quantities. However, the quality of lab room airflow or more specifically, the indoor environmental quality (IEQ) performance of a lab, beyond just temperature or perhaps humidity, is rarely monitored due to sensor cost and calibration issues. This is unfortunate, since detailed IEQ monitoring data can be used to substantially reduce lab energy consumption, increase lab safety and with some additional analysis, this data can be used to perform effective continuous commissioning.

Rough set-based regionalisation in air quality monitoring  

Science Journals Connector (OSTI)

Regionalisation is to organise a large set of spatial objects into spatially contiguous regions despite optimising the homogeneity of the derived regions, while representing social and economic geography. To confront this problem, it is necessary to classify the regions to form groups that are homogeneous in air quality attributes. It is to develop a system that applies data mining techniques to study the distribution of air pollutants in Chennai, a metro city in India using vehicular ad hoc networking and map the distribution on the geographical map for effective policy making. In conventional regionalisation methods, the data points are assigned to a single region in a multidimensional attribute space affecting air pollution response. However, some data points, having distributed membership to more than one region, could not be justified and allocated to a single region. Rough set-based clustering technique is applied to regionalisation problem to resolve vague or overlapping regions. The overlapping regions are restructured to guarantee the homogeneity of the regions formed or altered. The investigations of the cluster validity tests confirm the effectiveness of rough set-based regionalisation in air quality modelling.

Analysis of historical residential air-conditioning equipment sizing using monitored data  

SciTech Connect (OSTI)

Monitored data were analyzed to determine whether residential air conditioners in the Pacific Northwest historically have been sized properly to meet or slightly exceed actual cooling requirements. Oversizing air-conditioning equipment results in a loss of efficiency because of increased cycling and also lowers humidity control. On the other hand, the penalty of undersizing air-conditioning equipment may be some loss of comfort during extremely hot weather. The monitored data consist of hourly space-conditioning electrical energy use and internal air temperature data collected during the past 7 years from 75 residences in the Pacific Northwest. These residences are equipped with central air conditioners or heat pumps. The periods with the highest cooling energy use were analyzed for each site. A standard industry sizing methodology was used for each site to determine a sizing estimate. Both the sizing recommendation based on Manual J and peak monitored loads are compared to the capacity of the installed equipment for each site to study how the actual capacity differed from both the estimate of proper sizing and from actual demands. Characteristics of the maximum cooling loads are analyzed here to determine which conditions put the highest demand on the air conditioner. Specifically, internal air temperature data are used to determine when the highest cooling loads occur, at constant thermostat settings or when the thermostat was set down. This analysis of monitored data also provides insight into the extent that occupant comfort may be affected by undersizing air conditioners. The findings of this research indicate that cooling equipment historically has often but not always been oversized beyond industry-recommended levels. However, some occupants in homes with undersized, properly sized, and, in rare occasions, even oversized cooling equipment appear to suffer because the cooling equipment cannot always provide adequate cooling. Key findings are summarized.

IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries  

Science Journals Connector (OSTI)

An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of air quality monitoring stations turned out to be different from modelling for permit granting. Of interest is not the peak value of a relevant immission parameter, but the places where this parameter is most likely to have a higher peak value compared with neighbouring places. For this study, modelling has been done for eleven years of hourly meteorological data. The eleven yearly immission fields obtained by modelling are synthesized using the minimum, median and maximum values of the P98,m24h values obtained for each receptor point. This synthesis of the modelling results was complemented with an analysis of the available immission data for the region, so that the resulting air quality monitoring network is expected to monitor the impact of all emissions, not only those emissions that are in the emission inventory used for modelling.

ENVIRONMENTAL SAMPLING USING LOCATION SPECIFIC AIR MONITORING IN BULK HANDLING FACILITIES  

SciTech Connect (OSTI)

Since the introduction of safeguards strengthening measures approved by the International Atomic Energy Agency (IAEA) Board of Governors (1992-1997), international nuclear safeguards inspectors have been able to utilize environmental sampling (ES) (e.g. deposited particulates, air, water, vegetation, sediments, soil and biota) in their safeguarding approaches at bulk uranium/plutonium handling facilities. Enhancements of environmental sampling techniques used by the IAEA in drawing conclusions concerning the absence of undeclared nuclear materials or activities will soon be able to take advantage of a recent step change improvement in the gathering and analysis of air samples at these facilities. Location specific air monitoring feasibility tests have been performed with excellent results in determining attribute and isotopic composition of chemical elements present in an actual test-bed sample. Isotopic analysis of collected particles from an Aerosol Contaminant Extractor (ACE) collection, was performed with the standard bulk sampling protocol used throughout the IAEA network of analytical laboratories (NWAL). The results yielded bulk isotopic values expected for the operations. Advanced designs of air monitoring instruments such as the ACE may be used in gas centrifuge enrichment plants (GCEP) to detect the production of highly enriched uranium (HEU) or enrichments not declared by a State. Researchers at Savannah River National Laboratory in collaboration with Oak Ridge National Laboratory are developing the next generation of ES equipment for air grab and constant samples that could become an important addition to the international nuclear safeguards inspector's toolkit. Location specific air monitoring to be used to establish a baseline environmental signature of a particular facility employed for comparison of consistencies in declared operations will be described in this paper. Implementation of air monitoring will be contrasted against the use of smear ES when used during unannounced inspections, design information verification, limited frequency unannounced access, and complementary access visits at bulk handling facilities. Analysis of technical features required for tamper indication and resistance will demonstrate the viability of successful application of the system in taking ES within a bulk handling location. Further exploration of putting this technology into practice is planned to include mapping uranium enrichment facilities for the identification of optimal for installation of air monitoring devices.

Project 57 Air Monitoring Annual Report - Fiscal Year 2013 (October 1, 2012 to September 30, 2013)  

SciTech Connect (OSTI)

The U.S. Department of Energy (DOE), National Nuclear Security Administration, Nevada Field Office (NNSA/NFO) is currently working to achieve regulatory closure of radionuclide-contaminated Soils sites under its auspices. Corrective Action Unit (CAU) 415, Project 57 No. 1 Plutonium Dispersion Site is located in Emigrant Valley, Nevada, on Range 4808A of the Nevada Test and Training Range (NTTR), and consists of one Corrective Action Site (CAS): NAFR-23-02, Pu Contaminated Soil. Closure plans being developed for the CAUs both on and off of the Nevada National Security Site (NNSS) may include postclosure monitoring for the possible release of radioactive contaminants. Determining the potential for transport of radionuclide-contaminated soils under ambient climatic conditions will facilitate an appropriate closure design and postclosure monitoring program. The DOE has authorized the Desert Research Institute (DRI) to conduct field assessments of potential transport of radionuclide-contaminated soil from the Project 57 site during ambient wind events. The assessment is intended to provide site-specific information on meteorological conditions that result in airborne soil particle redistribution, as well as determine which, if any, radiological contaminants may be entrained with the soil particles and estimate their concentrations.

Pacific Northwest National Laboratory Potential Impact Categories for Radiological Air Emission Monitoring  

SciTech Connect (OSTI)

In 2002, the EPA amended 40 CFR 61 Subpart H and 40 CFR 61 Appendix B Method 114 to include requirements from ANSI/HPS N13.1-1999 Sampling and Monitoring Releases of Airborne Radioactive Substances from the Stack and Ducts of Nuclear Facilities for major emission points. Additionally, the WDOH amended the Washington Administrative Code (WAC) 246-247 Radiation protection-air emissions to include ANSI/HPS N13.1-1999 requirements for major and minor emission points when new permitting actions are approved. A result of the amended regulations is the requirement to prepare a written technical basis for the radiological air emission sampling and monitoring program. A key component of the technical basis is the Potential Impact Category (PIC) assigned to an emission point. This paper discusses the PIC assignments for the Pacific Northwest National Laboratory (PNNL) Integrated Laboratory emission units; this revision includes five PIC categories.

Data Quality Objectives Supporting Radiological Air Emissions Monitoring for the PNNL Site  

SciTech Connect (OSTI)

Pacific Northwest National Laboratory (PNNL) is in the process of developing a radiological air monitoring program for the PNNL Site that is distinct from that of the nearby Hanford Site. The original DQO (PNNL-19427) considered radiological emissions at the PNNL Site from Physical Sciences Facility (PSF) major emissions units. This first revision considers PNNL Site changes subsequent to the implementation of the original DQO. A team was established to determine how the PNNL Site changes would continue to meet federal regulations and address guidelines developed to monitor air emissions and estimate offsite impacts of radioactive material operations. The result is an updated program to monitor the impact to the public from the PNNL Site. The team used the emission unit operation parameters and local meteorological data as well as information from the PSF Potential-to-Emit documentation and Notices of Construction submitted to the Washington State Department of Health (WDOH). The locations where environmental monitoring stations would most successfully characterize the maximum offsite impacts of PNNL Site emissions from the three PSF buildings with major emission units were determined from these data. Three monitoring station locations were determined during the original revision of this document. This first revision considers expanded Department of Energy operations south of the PNNL Site and relocation of the two offsite, northern monitoring stations to sites near the PNNL Site fenceline. Inclusion of the southern facilities resulted in the proposal for a fourth monitoring station in the southern region. The southern expansion added two minor emission unit facilities and one diffuse emission unit facility. Relocation of the two northern stations was possible due to the use of solar power, rather than the previous limitation of the need for access to AC power, at these more remote locations. Addendum A contains all the changes brought about by the revision 1 considerations. This DQO report also updates the discussion of the Environmental Monitoring Plan for the PNNL Site air samples and how existing Hanford Site monitoring program results could be used. This document of Data Quality Objectives (DQOs) was prepared based on the U.S. Environmental Protection Agency (EPA) Guidance on Systematic Planning Using the Data Quality Objectives Process, EPA, QA/G4, 2/2006 (EPA 2006) as well as several other published DQOs.

Associations between ambient air pollution and bone turnover markers in 10-year old children: Results from the \\{GINIplus\\} and \\{LISAplus\\} studies  

Science Journals Connector (OSTI)

Abstract Negative associations between bone turnover markers and bone mineral density have been reported. In order to study the association between ambient air pollution and bone turnover markers, as indicators of bone loss, we investigated associations between land-use regression modeled air pollution (NO2, PM2.5 mass, PM2.5 – 10 [coarse particles], PM10 mass and PM2.5 absorbance) and bone turnover markers in 2264 children aged 10 years. Serum osteocalcin and C-terminal telopeptide of type I collagen (CTx), measured by Modular-System (Roche), were the two bone turnover markers considered in this analysis. In total population, NO2, PM2.5 – 10 and PM10 mass exposure were positively and significantly associated with both osteocalcin and CTx. A 2.5 (95% CI: 0.6, 4.4) ng/ml increase in osteocalcin and a 24.0 (95% CI: 6.7, 41.3) ng/L increase in \\{CTx\\} were observed per IQR (6.7 ?g/m3) increase in NO2, independent of socioeconomic status, sex, age, pubertal status, fasting status and total physical activity. The estimated coefficients were 3.0 (95% CI: 0.1, 5.8) for osteocalcin and 32.3 (95% CI: 6.1, 58.5) for \\{CTx\\} with PM2.5 – 10; 3.2 (95% CI: 0.0, 6.4) for osteocalcin and 30.7 (95% CI: 1.7, 59.7) for \\{CTx\\} with PM10. Children living close to a major road (? 350 m) had higher levels of both osteocalcin (1.4 [?1.2, 4.0] ng/ml) and \\{CTx\\} (16.2 [?7.4, 39.8] ng/L). The adverse impact of ambient air pollution on bone turnover rates observed in one of the study areas showed stimulation of more such studies.

Background monitoring of air toxics at the Waste Isolation Pilot Plant  

SciTech Connect (OSTI)

The Waste Isolation Pilot Plant (WIPP), located southeast of Carlsbad, New Mexico, has been constructed as a permanent repository for containerized solid or solidified transuranic (TRU) mixed waste. The repository is constructed in a massive salt bed formation, 2,150 feet below the surface. The WIPP has been granted a No-Migration Variance by the US Environmental Protection Agency (EPA) according to the requirements of 40 CFR 268.6. As part of the variance, a detailed air monitoring program has been developed for the facility. The purpose of the program is to detect airborne releases of hazardous constituents at the earliest practicable time. Routine background monitoring for volatile organic compounds (VOCs) has been performed at WIPP for the last two years. The monitoring program routinely quantifies airborne concentrations of five VOCs in the ventilation airstream of the underground facility, using Compendium Method TO-14. This paper describes the monitoring program in-place at the facility and presents a summary of the monitoring results for the last two years.

The influence of salt aerosol on alpha radiation detection by WIPP continuous air monitors  

SciTech Connect (OSTI)

Alpha continuous air monitors (CAMs) will be used at the Waste Isolation Pilot Plant (WIPP) to measure airborne transuranic radioactivity that might be present in air exhaust or in work-place areas. WIPP CAMs are important to health and safety because they are used to alert workers to airborne radioactivity, to actuate air-effluent filtration systems, and to detect airborne radioactivity so that the radioactivity can be confined in a limited area. In 1993, the Environmental Evaluation Group (EEG) reported that CAM operational performance was affected by salt aerosol, and subsequently, the WIPP CAM design and usage were modified. In this report, operational data and current theories on aerosol collection were reviewed to determine CAM quantitative performance limitations. Since 1993, the overall CAM performance appears to have improved, but anomalous alpha spectra are present when sampling-filter salt deposits are at normal to high levels. This report shows that sampling-filter salt deposits directly affect radon-thoron daughter alpha spectra and overall monitor efficiency. Previously it was assumed that aerosol was mechanically collected on the surface of CAM sampling filters, but this review suggests that electrostatic and other particle collection mechanisms are more important than previously thought. The mechanism of sampling-filter particle collection is critical to measurement of acute releases of radioactivity. 41 refs.

Constraining uncertainties about the sources and magnitude of ambient air exposures to polycyclic aromatic hydrocarbons (PAHs): The state of Minnesota as a case study  

SciTech Connect (OSTI)

Emissions data are often lacking or uncertain for many airborne contaminants. Chemicals, such as polycyclic aromatic hydrocarbons (PAHs), emitted from combustion sources, fall into this category. Currently available ambient-air emission inventories of PAHs either fail to account for population-based activities (such as residential wood combustion and motor vehicle activity) and/or report ''total PAH'' or particulate organic matter emissions instead of individual compounds. We measure the degree of overlap between predicted concentrations from estimated emissions with measured concentrations. Our analysis is, based on probabilistic analysis of measured outdoor air concentrations with those predicted from mass-balance models. Based on available information, we estimate the relative magnitude of emissions from four major sources of PAHs to outdoor air- (1) on-road motor vehicles, including light-duty gasoline vehicles and diesel-powered buses and medium and heavy duty trucks; (2) residential wood combustion; and (3) power generation from external combustion boilers. We use the CalTOX regional multimedia mass-balance model to evaluate our emissions estimates in rural and urban regions of the state of Minnesota, USA. We compare model estimates of outdoor PAH airborne concentrations with those reported by the Minnesota Children's Pesticide Exposure Study (MNCPES). With these measured concentrations we probabilistically evaluate our emissions and interpret the reliability of our emissions estimates for specific PAHs. The median estimates of our predicted outdoor air concentrations agree within an order of magnitude of measured concentrations. For four representative PAHs, we were able to obtain a reasonable degree of overlap between empirical and predicted distributions of outdoor air concentrations. Our combination of models, emissions estimates, and empirical concentration data estimate exposure in a manner that is more reliable than any of these tools alone. Thereby, we increase our confidence about our plausible ranges of emissions and predicted concentrations.

Calculation of SY tank annulus continuous air monitor readings after postulated leak scenarios  

SciTech Connect (OSTI)

The objective of this work was to determine whether or not a continuous air monitor (CAM) monitoring the annulus of one of the SY Tanks would be expected to alarm after three postulated leak scenarios. Using data and references provided by Lockheed Martin`s Tank Farm personnel, estimated CAM readings were calculated at specific times after the postulated scenarios might have occurred. Potential CAM readings above background at different times were calculated for the following leak scenarios: Leak rate of 0.01 gal/min; Leak rate of 0.03 gal/min (best estimate of the maximum probable leak rate from a single-shell tank); and Leak of 73 gal (equivalent to a {1/4}-in. leak on the floor of the annulus). The equation used to make the calculations along with descriptions and/or explanations of the terms are included, as is a list of the assumptions and/or values used for the calculations.

Monitoring building energy consumption, thermal performance, and indoor air quality in a cold climate region  

Science Journals Connector (OSTI)

Abstract Buildings are major consumers of the world's energy. Optimizing energy consumption of buildings during operation can significantly reduce their impact on the global environment. Monitoring the energy usage and performance is expected to aid in reducing the energy consumption of occupants. In this regard, this paper describes a framework for sensor-based monitoring of energy performance of buildings under occupancy. Different types of sensors are installed at different locations in 12 apartment units in a building in Fort McMurray, Alberta, Canada to assess occupant energy usage, thermal performance of the building envelope, and indoor air quality (IAQ). The relationship between heating energy consumption and the thermal performance of building envelope and occupant comfort level is investigated by analyzing the monitoring data. The results show that the extent of heat loss, occupant comfort level, and appliance usage patterns have significant impacts on heating energy and electricity consumption. This study also identifies the factors influencing the poor IAQ observed in some case-study units. In the long term, it is expected that the extracted information acquired from the monitoring system can be used to support intelligent decisions to save energy, and can be implemented by the building management system to achieve financial, environmental, and health benefits.

This document provides a final report covering tasks 1.0 and subtasks 2.1, 2.2, and 2.5 of task 2.0 of the Statement of Project Objectives and constitutes the final project deliverable. The proposed work was to have provided physical measurements and analyses of large-scale rock mass response to pressure cycling. The goal was to develop proof-of-concept data for a previously developed and DOE sponsored technology (RMRCT or Refrigerated-Mined Rock Cavern Technology). In the RMRCT concept, a room and pillar mine developed in rock serves as a pressure vessel. That vessel will need to contain pressure of about 1370 psi (and cycle down to 300 psi). The measurements gathered in this study would have provided a means to determine directly rock mass response during cyclic loading on the same scale, under similar pressure conditions. The CAES project has been delayed due to national economic unrest in the energy sector.

Air Monitoring Leads to Discovery of New Contamination at Radioactive Waste Disposal Site (Area G) at LANL  

SciTech Connect (OSTI)

Air monitoring at Area G, the low-level radioactive waste disposal area at Los Alamos National Laboratory, revealed increased air concentrations of {sup 239}Pu and {sup 241}Am at one location along the north boundary. This air monitoring location is a couple of meters north of a dirt road used to access the easternmost part of Area G. Air concentrations of {sup 238}Pu were essentially unaffected, which was puzzling because the {sup 238}Pu and {sup 239}Pu are present in the local, slightly contaminated soils. Air concentrations of these radionuclides increased about a factor of ten in early 1995 and remained at those levels until the first quarter of 1996. During the spring of 1996 air concentrations again increased by a factor of about ten. No other radionuclides were elevated and no other Area G stations showed elevations of these radionuclides. After several formal meetings didn't provide an adequate cause for the elevations, a gamma survey was performed and showed a small area of significant contamination just south of the monitor location. We found in February, 1995, a trench for a water line had been dug within a meter of so of the air stations. Then, during early 1996, the dirt road was rerouted such that its new path was directly over the unknown contamination. It appears that the trenching brought contaminated material to the surface and caused the first rise in air concentrations and then the rerouting of the road over the contamination caused the second rise, during 1996. We also found that during 1976 and 1977 contaminated soils from the clean-up of an old processing facility had been spread over the filled pits in the vicinity of the air monitors. These soils were very low in 238Pu which explains why we saw very little {sup 238}Pu in the increased air concentrations. A layer of gravel and sand was spread over the contaminated area. Although air concentrations of {sup 239}Pu and {sup 241}Am dropped considerably, the y have not returned to pre-1995 levels.

AIRNET Data from Los Alamos National Laboratory: Air Concentration Data by Site and Isotope/Element  

DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

Ambient monitoring is the systematic, long-term assessment of pollutant levels by measuring the quantity and types of certain pollutants in the surrounding, outdoor air. The purpose of AIRNET, LANL's ambient air monitoring network, is to monitor locations where people live or work. The community of Los Alamos is downwind from LANL, so there are many monitoring stations in and around the town. AIRNET stations monitor 24 hours a day, 365 days of the year. Particulates are collected on a filter and analyzed every two weeks for identification of analytes and assessment of the potential impact on the public. Emissions measurement is the process of monitoring materials vented from buildings. Air samples are taken from building exhaust units, called stacks, and are then analyzed for particulate matter, tritium, and radioactive gases and vapors. A computer model uses the emission data to determine the dispersion. Stack monitoring is also used to measure emissions that cannot be measured by AIRNET stations.

Air monitoring in the Arctic: Results for selected persistent organic pollutants for 1992  

SciTech Connect (OSTI)

The Arctic is generally considered to be a pristine environment and has few direct inputs of organochlorine compounds (OCs), including pesticides, herbicides, polychlorinated biphenyls, or polycyclic aromatic hydrocarbons (PAHs). In spite of this, airborne concentrations of persistent organic pollutants (POPs) are comparable to those in more populated and industrialized regions of North America and Europe. Atmospheric transport and condensation of compounds at low temperature conditions are important factors contributing to the presence of contaminants in the Arctic. A long-term program has been established to measure the airborne concentrations of POPs in the Arctic. The first station at Alert was established in January 1992. The concentrations measured in the first year of monitoring for 18 compounds that are representative of different compound classes are presented. Seasonal variations for PAHs are similar to those for Arctic haze and peak during winter. For example, in the coldest period, october to April, benzo[a]pyrene concentrations were found to average 20 pg/m{sup 3}, whereas, in contrast, during the relatively warm May to September period, average levels were 1.0 pg/m{sup 3}. For OCs, the seasonal cycle was not as pronounced as that for PAH compounds. For example, {alpha}-hexachlorocyclohexane was found at Alert at average concentrations of 62 and 57 pg/m{sup 3}, respectively, during cold and warm periods. It is postulated that air concentrations are influenced by advection from distant source regions as well as exchange with local (Arctic Ocean) surfaces.

Research Research Ambient Monitoring - NETL / OST Monitoring Site This project is part of the NETL In-House R&D Ambient Air Quality Research Program. As part of the overall DOE-FE air quality sampling and analysis activities, NETL's Office of Science & Technology (OST) has initiated an in-house ambient monitoring program that builds upon the Center's core capabilities and competencies in inorganic and organic analyses and instrumentation. The program has culminated with the establishment of a fine particulate/air toxics sampling station at the Center's research laboratory in Pittsburgh. This air monitoring station consists of a new 715 ft2 indoor facility housing equipment to monitor continuously gaseous pollutants O3, SO2, NH3, NOy, NOx, CO, H2S, and peroxide, and PM2.5 particulates containing carbon and polyaromatic hydrocarbons. In addition, a fully-instrumented, fourteen bay rack has been constructed to support a variety of ambient monitoring equipment. OST will also collaborate with Consol and the Allegheny (PA) County Health Department in evaluating the performance of PM2.5 FRM samplers. The NETL sampling station will use an existing 10-meter meteorological tower that has been collecting weather-related data for the past seven years. Two in-house laboratories have been completely renovated to support the analysis of PM2.5/air toxics samples, including the installation of a Kratos MS50 high-resolution mass spectrometer for the detailed characterization of organic compounds.

Air pollutant monitoring for the East Bay Children's Respiratory Health Study  

SciTech Connect (OSTI)

This report describes the methodology and presents the summary results of the air pollutant monitoring program conducted by Lawrence Berkeley National Laboratory in support of the East Bay Children's Respiratory Health Study. The full study is examining the effects of chronic exposure to traffic-related pollutants on respiratory health among 3rd and 4th grade children attending ten neighborhood elementary schools in the San Francisco East Bay Area (Hayward, San Leandro and Oakland, CA). The demographically similar schools are located at varying distances from the I-880 and CA-92 freeways. Several schools were selected because they are located within 300 m in the predominant downwind direction (east) from either of the freeways. Measurements of multiple pollutants were made outdoors at the schools over 1-2 week intervals for 14 weeks in spring and eight weeks in fall 2001 using a custom-designed and validated package of commercially available monitoring equipment. Particulate matter was sampled over all hours (24 h per day) or during schools hours only with battery-operated programmable pumps and inlet devices for PM{sub 10} and PM{sub 2.5}. These pumps were modified to allow for up to 10 days of continuous operation. Fine particle mass and black carbon (BC) were determined from the collected filters. Nitrogen oxides (NO{sub x} and NO{sub 2}) were measured with passive samplers. Carbon monoxide (CO) was measured continuously with an electrochemical sensor. Gasoline-related volatile organic compounds (VOCs) were measured with passive samplers during three 4-week intervals in spring 2001 and two 4-week periods in early 2002. All samplers were deployed in a metal cabinet located outside at each school. Ranges of study average pollutant concentrations (all-hours) at the ten individual schools were: NO{sub x}, 33-68 ppb; NO{sub 2}, 19-31 ppb; PM{sub 10} mass, 27-32 {micro}g/m{sup 3}; PM{sub 2.5} mass, 12-15 {micro}g/m{sup 3}; and BC associated with PM{sub 2.5}, 0.6-1.0 {micro}g/m{sup 3}. Although statistical analysis of the data is yet to be performed, some general observations can be made. Absolute pollutant levels varied by season and week, but the simultaneous sampling design allowed for comparisons of concentrations among schools during each interval. Pollutant concentrations at each school were normalized to the sampling period averages among all schools. The normalized concentrations were generally consistent at each school throughout the entire study, suggesting that measured differences represent ongoing conditions and chronic exposures in the vicinities of the schools. Substantially elevated concentrations of NO{sub x}, NO{sub 2}, and BC, and somewhat elevated concentrations of PM{sub 2.5} were observed at one school located less than 100 meters to the east of I-880. Normalized concentrations of NO{sub x}, NO{sub 2}, and BC were also higher at the three other ''nearby and downwind'' schools relative to those located far from any freeway or other major traffic source. An ancillary monitoring program was implemented to examine the correlation between school-based pollutant measurements and measurements throughout the neighborhoods adjacent to three of the schools. Volunteer households were obtained from among the families of participating schoolchildren. Concentrations of NO{sub x} and NO{sub 2} were measured with passive samplers outside the homes of these volunteers during one of two 1-week periods in spring 2002. Simultaneous measurements were conducted at all ten of the schools and a central monitoring station during each week. The neighborhoods surrounding two schools were predominantly upwind of the I-880 freeway, while the neighborhood surrounding the other school was downwind from I-880. The overall distribution of concentrations observed for the residences near the downwind school appeared to be substantially higher than the regional background concentrations. The variability observed within the neighborhoods appeared to be, at least in part, explained by the proximity of individual residences to the freeway or

Lessons from UNSCOM and IAEA regarding remote monitoring and air sampling  

SciTech Connect (OSTI)

In 1991, at the direction of the United Nations Security Council, UNSCOM and IAEA developed plans for On-going Monitoring and Verification (OMV) in Iraq. The plans were accepted by the Security Council and remote monitoring and atmospheric sampling equipment has been installed at selected sites in Iraq. The remote monitoring equipment consists of video cameras and sensors positioned to observe equipment or activities at sites that could be used to support the development or manufacture of weapons of mass destruction, or long-range missiles. The atmospheric sampling equipment provides unattended collection of chemical samples from sites that could be used to support the development or manufacture of chemical weapon agents. To support OMV in Iraq, UNSCOM has established the Baghdad Monitoring and Verification Centre. Imagery from the remote monitoring cameras can be accessed in near-real time from the Centre through RIF communication links with the monitored sites. The OMV program in Iraq has implications for international cooperative monitoring in both global and regional contexts. However, monitoring systems such as those used in Iraq are not sufficient, in and of themselves, to guarantee the absence of prohibited activities. Such systems cannot replace on-site inspections by competent, trained inspectors. However, monitoring similar to that used in Iraq can contribute to openness and confidence building, to the development of mutual trust, and to the improvement of regional stability.

Radiation control coatings installed on federal buildings at Tyndall Air Force Base. Volume 2: Long-term monitoring and modeling  

SciTech Connect (OSTI)

The US Department of Energy`s (DOE`s) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the federal sector. One such effort, the New Technology Demonstration Program (NTDP), seeks to evaluate new energy-saving US technologies and secure their more timely adoption by the US government. Through a partnership with a federal site, the utility serving the site, a manufacturer of an energy-related technology, and other organizations associated with these interests, DOE can evaluate a new technology. The results of the program give federal agency decision makers more hands-on information with which to validate a decision to utilize a new technology in their facilities. This is the second volume of a two-volume report that describes the effects of radiation control coatings installed on federal buildings at Tyndall Air Force Base (AFB) in Florida by ThermShield International. ORNL`s Buildings Technology Center (BTC) was assigned the responsibility for gathering, analyzing, and reporting on the data to describe the effects of the coatings. The first volume described the monitoring plan and its implementation, the results of pre-coating monitoring, the coating installation, results from fresh coatings compared to pre-coating results, and a plan to decommission the monitoring equipment. This second volume updates and completes the presentation of data to compare performance of fresh coatings with weathered coatings.

Monitoring  

SciTech Connect (OSTI)

The invention provides apparatus and methods which facilitate movement of an instrument relative to an item or location being monitored and/or the item or location relative to the instrument, whilst successfully excluding extraneous ions from the detection location. Thus, ions generated by emissions from the item or location can successfully be monitored during movement. The technique employs sealing to exclude such ions, for instance, through an electro-field which attracts and discharges the ions prior to their entering the detecting location and/or using a magnetic field configured to repel the ions away from the detecting location.

Twelve Months of Air Quality Monitoring at Ash Meadows National Wildlife Refuge, Southwestern Rural Nevada, U.S.A (EMSI April 2007)  

SciTech Connect (OSTI)

The one year of air quality monitoring data collected at the Ash Meadows National Wildlife Refuge (NWR) was the final part of the air quality "Scoping Studies" for the Environmental Monitoring Systems Initiative (EMSI) in southern and central Nevada. The objective of monitoring at Ash Meadows was to examine aerosol and meteorological data, seasonal trends in aerosol and meteorological parameters as well as to examine evidence for long distance transport of some constituents. The 9,307 hectare refuge supports more than 50 springs and 24 endemic species, including the only population of the federally listed endangered Devil’s Hole pupfish (Cyprinodon diabolis) (U.S. Fish and Wildlife Service, 1990). Ash Meadows NWR is located in a Class II air quality area, and the aerosol measurements collected with this study are compared to those of Interagency Monitoring of Protected Visual Environments (IMPROVE) sites. Measurements taken at Ash Meadows NWR over a period of 12 months provide new baseline air quality and meteorological information for rural southwestern Nevada, specifically Nye County and the Amargosa Valley.

COMPARATIVE EVALUATION OF AMBIENT FINE PARTICULATE MATTER (PM2.5) DATA OBTAINED FROM URBAN AND RURAL MONITORING SITES ALONG THE UPPER OHIO RIVER VALLEY  

SciTech Connect (OSTI)

The report discusses the following conclusions: (1) The TEOM equipment performed as well as the sequential filter samplers in accounting for ambient PM{sub 2.5} levels; however, the FRM-obtained data was consistently lower than the averages from the TEOM/DRI-SFS measurements; (2) The trending in the PM{sub 2.5} levels was similar for Lawrenceville and Holbrook, which represent an urban and a rural site sixty-five miles apart. This implies that the PM{sub 2.5} levels appear to be impacted more by regional than by local effects; (3) The absolute median PM{sub 2.5} levels were slightly higher for Lawrenceville than for Holbrook, implying that local urban environmental contributions had a minor but measurable effect on total PM{sub 2.5} mass concentration; (4) PM{sub 2.5} and PM{sub 10} mass concentration levels were consistently higher in summer than in winter, with intermediate levels observed in the spring and fall; (5) Sulfate levels predominated in the speciation data obtained from both the Holbrook and the Lawrenceville sites during winter and summer intensive sampling. Sulfate level measured at Holbrook were higher than those taken at Lawrenceville regardless of the season; (6) Ammonium levels remained relatively constant between seasons and between sites; (7) Nitrate levels measured at Lawrenceville were higher than those measured at Holbrook during winter intensive sampling. Nitrate levels measured during the summer intensive period were found to be very low at both locations; (8) In general, the predominant inorganic fraction of the samples analyzed could be described as being composed of a mixture of ammonium bisulfate and ammonium sulfate with minor amounts of ammonium nitrate; (9) The PM10 fraction had a larger percentage of geological material and a smaller percentage of condensable material (ammonium bisulfate, ammonium sulfate, ammonium nitrate and total carbon species) than the PM{sub 2.5} fraction for samples collected in winter at Lawrenceville; and (10) Most high PM{sub 2.5} episodes occurred when the predominating wind direction was from the South-West. (11) Plots of ozone vs. NO{sub x} suggest chemical reaction between these molecules since a high concentration of one always results in a low concentration of the other. The analysis of the acquired data has so far addressed three of the four scientific questions originally posed. More data analysis is on-going including the correlation between O{sub 3} and PM{sub 2.5} levels and the correlation of mass data with meteorological observations.

Assessing air quality in Hong Kong: A proposed, revised air pollution index (API)  

Science Journals Connector (OSTI)

The Environment Protection Department of Hong Kong has been using an air pollution index (API) to report the status of ambient air quality since 1995. Such an index system was first developed by the USA Environmental Protection Authority. The API compares five main air pollutants, i.e. sulfur dioxide (SO2), respirable suspended particulates (RSP), nitrogen dioxide (NO2), carbon monoxide (CO) and Ozone (O3) as sub-indexes, which are calculated separately from a segmented linear function that transforms ambient pollutants concentrations into a normalized scale extending from 0 to 500. The resultant pollution level is described by the maximal value of these five sub-indexes. The limitation of this API system is that it considers only one pollutant with the maximum value at a time but reflects other pollutants concurrently. In this study, a revised air quality index (RAPI) is proposed based on the entropy function, which combines the effect of all pollutants on public health. The design of the revised index is based on database of air pollutants collected at two air quality monitoring stations in Hong Kong, i.e. a roadside station in Mong Kok and a general station in Sha Tin. Compared with the existing API, values of RAPI (calculated from data collected for API) at both stations are at higher levels and provide more information of levels of all pollutants. Therefore, RAPI should be representatively and widely used to provide the public with a better indicator of air quality. In addition, variations and oscillations of pollutants concentrations were also examined and the results show that RSP and NO2 contribute more to the overall pollution level than other components. It is suggested that more abatement strategies be focused on these pollutants to improve air quality in the future.

Performance of unglazed solar ventilation air pre-heaters for broiler barns  

Science Journals Connector (OSTI)

Solar radiation is an interesting heat source for applications requiring a limited amount of energy, such as pre-heating cold fresh air used in venting livestock barns. The objective of this study was to evaluate the energy recovery efficiency of a solar air pre-heater consisting of an unglazed perforated black corrugated siding where the incoming fresh ventilation air picks up heat from its face and back. Installed on the southeast wall of two broiler barns located 40 km east of Montreal, Canada, the performance of solar air pre-heaters was monitored over 2 years. Sensors inside the barns monitored the temperature of the ambient air, that pre-heated by the solar collector and that exhausted by one of the three operating fans. An on-site weather station measured ambient air temperature, wind direction and velocity and radiation energy absorbed on a vertical plane parallel to the unglazed solar air pre-heaters. The measured vertical solar radiation value was used to evaluate the heat recovery efficiency of the unglazed solar air pre-heaters. Using data from the Varennes Environment Canada weather station located 30 km northwest, the solar sensors were found to measure the absorbed solar radiation with a maximum error of 7%, including differences in exterior air moisture. Unglazed, the efficiency of the solar air pre-heaters reached 65% for wind velocities under 2 m/s, but dropped below 25% for wind velocities exceeding 7 m/s. Nevertheless, the unglazed solar air pre-heaters were able to reduce the heating load especially in March of both years. Over a period starting in November and ending in March, the solar air heaters recovered an energy value equivalent to an annual return on investment of 4.7%.

Exploring relationships between outdoor air particulate-associated Exploring relationships between outdoor air particulate-associated polycyclic aromatic hydrocarbon and PM2.5: A case study of benzo(a)pyrene in California metropolitan regions Title Exploring relationships between outdoor air particulate-associated polycyclic aromatic hydrocarbon and PM2.5: A case study of benzo(a)pyrene in California metropolitan regions Publication Type Journal Article LBNL Report Number LBNL-514E Year of Publication 2008 Authors Lobscheid, Agnes B., Thomas E. McKone, and D. A. Valleroc Journal Atmospheric Environment Volume 41 Start Page Chapter Pagination 5659-5672 Abstract Polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) are co-pollutants emitted as by-products of combustion processes. Convincing evidence exists for PAHs as a primary toxic component of fine PM (PM2.5). Because PM2.5 is listed by the US EPA as a "Criteria Pollutant," it is monitored regularly at sites nationwide. In contrast, very limited data is available on measured ambient air concentrations of PAHs. However, between 1999-2001, ambient air concentrations of PM2.5 and benzo(a)pyrene (BaP) are available for California locations. We use multivariate linear regression models (MLRMs) to predict ambient air levels of BaP in four air basins based on reported PM2.5 concentrations and spatial, temporal and meteorological variables as variates. We obtain an R2 ranging from 0.57-0.72 among these basins. Significant variables (p<0.05) include the average daily PM2.5 concentration, wind speed, temperature and relative humidity, and the coastal distance as well as season, and holiday or weekend. Combining the data from all sites and using only these variables to estimate ambient BaP levels, we obtain an R2 of 0.55. These R2-values, combined with analysis of the residual error and cross validation using the PRESS-statistic, demonstrate the potential of our method to estimate reported outdoor air PAH exposure levels in metropolitan regions. These MLRMs provide a first step towards relating outdoor ambient PM2.5 and PAH concentrations for epidemiological studies when PAH measurements are unavailable, or limited in spatial coverage, based on publicly available meteorological and PM2.5 data

Radiation control coatings installed on federal buildings at Tyndall Air Force Base. Volume 1: Pre-coating monitoring and fresh coating results  

SciTech Connect (OSTI)

The US Department of Energy`s (DOE`s) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the federal sector. One such effort, the New Technology Demonstration Program (NTDP), seeks to evaluate new energy-saving US technologies and secure their more timely adoption by the US government. Through a partnership with a federal site, the utility serving the site, a manufacturer of an energy-related technology, and other organizations associated with these interests, DOE can evaluate a new technology. The results of the program give federal agency decision makers more hands-on information with which to validate a decision to utilize a new technology in their facilities. The partnership of these interests is secured through a cooperative research and development agreement (CRADA), in this case between Lockheed Martin Energy Research Corporation, the manager of the Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, and ThermShield International, Ltd., the manufacturer of the technology. This is the first volume of a two-volume report that describes the effects of radiation control coatings installed on federal buildings at Tyndall Air Force Base (AFB) in Florida by ThermShield International. ORNL`s Buildings Technology Center (BTC) was assigned the responsibility for gathering, analyzing, and reporting on the data to describe the effects of the coatings. This volume describes the monitoring plan and its implementation, the results of pre-coating monitoring, the coating installation, results from fresh coatings compared to pre-coating results, and a plan to decommission the monitoring equipment. By including results from roofs at Tyndall AFB and from an outdoor test facility at the BTC, the data cover the range from poorly insulated to well-insulated roofs and two kinds of radiation control coatings on various roof membranes.

Detecting and defining air pollutants: one laboratory's experiences and approaches  

SciTech Connect (OSTI)

The Texas Air Control Board is the agency responsible for maintaining the quality of the ambient air of Texas. An extensive network of continuous and noncontinuous monitors is used to defect air quality trends in the state. The samples submitted may be gaseous, liquid, or solid. X-ray fluorescence spectroscopy (XRF) is used for various elements. XRF was used specifically for lead emissions, sulfur dioxide emissions and toxic metals. However, atomic absorption is better for beryllium and arsenic. Gas chromatography (GC), high pressure liquid chromatography (HPLC), and gas chromatography/mass spectrometry (GC/MS) are employed in organic analysis as complements to each other. HPLC has been effectively used in the analysis of samples for herbicides. The defection of vinyl chloride monomer (VCM) is accomplished with a photoionization defector (PID) and flame ionization detector (FID) in series. There are many examples of a multi-instrument approach to analysis of samples. Gas chromatography and mass spectroscopy were used for nitrobenzene analysis. The complexity of ambient air sampler often requires a multinstrumental approach if the sample is to be qualitatively and quantitatively analyzed so that the information can be used for corrective action or to identify potential problems of air pollution. 2 figures.

Cooling Cooling Jump to: navigation, search Dictionary.png Air Cooling: Air cooling is commonly defined as rejecting heat from an object by flowing air over the surface of the object, through means of convection. Air cooling requires that the air must be cooler than the object or surface from which it is expected to remove heat. This is due to the second law of thermodynamics, which states that heat will only move spontaneously from a hot reservoir (the heat sink) to a cold reservoir (the air).

Electrostatic monitoring  

DOE Patents [OSTI]

The apparatus and method provide a technique for more simply measuring alpha and/or beta emissions arising from items or locations. The technique uses indirect monitoring of the emissions by detecting ions generated by the emissions, the ions being attracted electrostatically to electrodes for discharge of collection. The apparatus and method employ a chamber which is sealed around the item or location during monitoring with no air being drawn into or expelled from the chamber during the monitoring process. A simplified structure and operations arises as a result, but without impairing the efficiency and accuracy of the detection technique.

Geothermal power production: impact assessments and environmental monitoring  

SciTech Connect (OSTI)

The role that baseline and postoperational environmental monitoring plays in assessing impacts of geothermal power production is emphasized. Based on experience in the Imperial Valley, where substantial geothermal resources exist, the important characteristics of monitoring programs involving subsidence, seismicity, and air and water quality are examined. The importance of environmental monitoring for situations where predictive models either do not exist (e.g., seismicity), or are still being developed (e.g., land subsidence) are discussed. In these cases the need for acquiring and analyzing data that can provide timely information on changes caused by geothermal operations are emphasized. Monitoring is also useful in verifying predictions of air quality changes - in particular, violations of ambient standards after control technologies are implemented. Water quality can be monitored with existing sampling programs where the potential for geothermal impacts is thought to be rather small. The significant issues in these environmental areas, the status of baseline data and predictive capability that currently exists, and the need for future monitoring and modeling programs to assess the impacts of geothermal development are summarized.

New sensor for measurement of low air flow velocity. Phase I final report  

SciTech Connect (OSTI)

The project described here is the Phase I feasibility study of a two-phase program to integrate existing technologies to provide a system for determining air flow velocity and direction in radiation work areas. Basically, a low air flow sensor referred to as a thermocouple flow sensor has been developed. The sensor uses a thermocouple as its sensing element. The response time of the thermocouple is measured using an existing in-situ method called the Loop Current Step Response (LCSR) test. The response time results are then converted to a flow signal using a response time-versus-flow correlation. The Phase I effort has shown that a strong correlation exists between the response time of small diameter thermocouples and the ambient flow rate. As such, it has been demonstrated that thermocouple flow sensors can be used successfully to measure low air flow rates that can not be measured with conventional flow sensors. While the thermocouple flow sensor developed in this project was very successful in determining air flow velocity, determining air flow direction was beyond the scope of the Phase I project. Nevertheless, work was performed during Phase I to determine how the new flow sensor can be used to determine the direction, as well as the velocity, of ambient air movements. Basically, it is necessary to use either multiple flow sensors or move a single sensor in the monitoring area and make flow measurements at various locations sweeping the area from top to bottom and from left to right. The results can then be used with empirical or physical models, or in terms of directional vectors to estimate air flow patterns. The measurements can be made continuously or periodically to update the flow patterns as they change when people and objects are moved in the monitoring area. The potential for using multiple thermocouple flow sensors for determining air flow patterns will be examined in Phase II.

Annual Report for 2008 - 2009 Detection Monitoring at the Environmental Management Waste Management Facility, Oak Ridge, Tennessee  

SciTech Connect (OSTI)

This annual Environmental Monitoring Report (EMR) presents results of environmental monitoring performed during fiscal year (FY) 2009 (October 1, 2008 - September 30, 2009) at the Environmental Management Waste Management Facility (EMWMF). The EMWMF is an operating state-of-the-art hazardous waste landfill located in Bear Creek Valley (BCV) west of the U.S. Department of Energy (DOE) Y-12 National Security Complex (Y-12) on the DOE Oak Ridge Reservation (ORR) in Oak Ridge, Tennessee (Appendix A, Fig. A.1). Opened in 2002 and operated by a DOE prime contractor, Bechtel Jacobs Company LLC (BJC), the EMWMF was built specifically to accommodate disposal of acceptable solid wastes generated from Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) remedial actions for former waste sites and buildings that have been impacted by past DOE operations on the ORR and at DOE sites off the ORR within the state of Tennessee. Environmental monitoring at the EMWMF is performed to detect and monitor the impact of facility operations on groundwater, surface water, stormwater, and air quality and to determine compliance with applicable or relevant and appropriate requirements (ARARs) specified in governing CERCLA decision documents. Annually, the EMR presents an evaluation of the groundwater, surface water, stormwater, and air monitoring data with respect to the applicable EMWMF performance standards. The purpose of the evaluation is to: (1) identify monitoring results that indicate evidence of a contaminant release from the EMWMF to groundwater, surface water, stormwater, or air, and (2) recommend appropriate changes to the associated sampling and analysis requirements, including sampling locations, methods, and frequencies; field measurements; or laboratory analytes that may be warranted in response to the monitoring data. Sect. 2 of this annual EMR provides background information relevant to environmental monitoring at the landfill, including short descriptions of the facility, the hydrogeologic setting, CERCLA decision document requirements for environmental monitoring, and a summary of the EMWMF monitoring history to date. Sect. 3 identifies the respective groundwater, surface water, stormwater, and air monitoring locations at the EMWMF and outlines the associated sampling frequencies, field measurements, and laboratory analytes. Sect. 4 presents a concise technical evaluation of the groundwater, surface water, stormwater, and air monitoring data. Sect. 5 summarizes key monitoring results and data evaluation conclusions along with any recommended changes to groundwater, surface water, stormwater, or air monitoring at the EMWMF. Sect. 6 lists the documents and other technical reports referenced in the preceding narrative sections. Maps and other illustrations referenced in the narrative sections of this annual EMR are in Appendix A. Referenced summary tables of FY 2009 environmental monitoring data are in Appendix B (Groundwater), Appendix C (Surface Water), Appendix D (Stormwater), and Appendix E (Ambient Air).

Characterization of ambient particulate matter in the Paso del Norte region  

SciTech Connect (OSTI)

Air pollution in the Paso del Norte region, where West Texas abuts the southern boundary of New Mexico and the northern boundary of Chihuahua, Mexico is a common concern to the residents on both sides of the border. Parts of the region fail to meet the US and Mexican Ambient Air Quality Standards for particulate matter, ozone, and carbon monoxide. The regional air pollution problem is complicated due to arid climate, complex terrain topography, frequently occurring temperature inversions, extensive unpaved urban areas, an aging and poorly maintained vehicle fleet, and a number of other uncontrolled anthropogenic emission sources. The issue is further complicated by concerns arising from recent scientific evidence of the health effects associated with exposures to fine particulate matter. A study designed to address particulate matter (PM) air pollution problems in the region is currently undertaken by researchers from member universities of the Southwest Center for Environmental Research and Policy and several governmental agencies. The study attempts to (1) characterize the fine fraction of PM; (2) identify and characterize the major regional emission sources; (3) apportion the fine fraction of PM to the source emissions; and (4) establish a regional technological information clearinghouse. The short-term goal of this research is to initiate a research program to characterize, identify, and quantify the sources and nature of the PM in the region. The long-term goal of this study is to establish regional research capabilities to continue air quality monitoring, evaluation, modeling, and control after the implementation of the study. A scoping study to collect regional PM was conducted in December 1998.

Variable oxygen/nitrogen enriched intake air system for internal combustion engine applications  

DOE Patents [OSTI]

An air supply control system for selectively supplying ambient air, oxygen enriched air and nitrogen enriched air to an intake of an internal combustion engine includes an air mixing chamber that is in fluid communication with the air intake. At least a portion of the ambient air flowing to the mixing chamber is selectively diverted through a secondary path that includes a selectively permeable air separating membrane device due a differential pressure established across the air separating membrane. The permeable membrane device separates a portion of the nitrogen in the ambient air so that oxygen enriched air (permeate) and nitrogen enriched air (retentate) are produced. The oxygen enriched air and the nitrogen enriched air can be selectively supplied to the mixing chamber or expelled to atmosphere. Alternatively, a portion of the nitrogen enriched air can be supplied through another control valve to a monatomic-nitrogen plasma generator device so that atomic nitrogen produced from the nitrogen enriched air can be then injected into the exhaust of the engine. The oxygen enriched air or the nitrogen enriched air becomes mixed with the ambient air in the mixing chamber and then the mixed air is supplied to the intake of the engine. As a result, the air being supplied to the intake of the engine can be regulated with respect to the concentration of oxygen and/or nitrogen.

Inconsistencies in air quality metrics: 'Blue Sky' days and  

Science Journals Connector (OSTI)

International attention is focused on Beijing's efforts to improve air quality. The number of days reported as attaining the daily Chinese National Ambient Air Quality Standard for cities, called 'Blue Sky' days, has increased yearly from 100 in 1998 to 246 in 2007. However, analysis of publicly reported daily air pollution index (API) values for fine particulate matter (diameter?10 µm, PM10), indicates a discrepancy between the reported 'Blue Sky' days (defined as API?100, PM10?150 µg m?3) and published monitoring station data. Here I show that reported improvements in air quality for 2006–2007 over 2002 levels can be attributed to (a) a shift in reported daily PM10 concentrations from just above to just below the national standard, and (b) a shift of monitoring stations in 2006 to less polluted areas. I found that calculating daily Beijing API for 2006 and 2007 using data from the original monitoring stations eliminates a bias in reported PM10 concentrations near the 'Blue Sky' boundary, and results in a number of 'Blue Sky' days and annual PM10 concentration near 2002 levels in 2006 and 2007 (203 days and ~167 µg m?3 calculated for 2006—38 days fewer and a PM10 concentration ~6 µg m?3 higher than reported; 191 'Blue Sky' days and ~161 µg m?3 calculated for 2007—55 days fewer and a PM10 concentration ~12 µg m?3 higher than reported; 203 days and 166 µg m?3 were reported in 2002). Furthermore, although different pollutants were monitored before daily reporting began and less stringent standards were implemented in June 2000, reported annual average concentrations of particulate (diameter?100 µm, TSP) and nitrogen dioxide (NO2) indicate no improvement between 1998 and 2002. This analysis highlights the sensitivity of monitoring data in the evaluation of air quality trends, and the potential for the misinterpretation or manipulation of these trends on the basis of inconsistent metrics.

Effects of particulate air pollution and ozone on lung function in non-asthmatic children  

Science Journals Connector (OSTI)

AbstractIntroduction Information on the long-term effects of different air pollutant levels on lung function is relatively lacking in Asia and still inconclusive in the world. Age differential effects of air pollution are not known. Objectives To assess the acute and subchronic effects of ambient air pollution on lung function and compared among children of different ages. Methods From April to May 2011, a nationwide study was conducted on schoolchildren aged 6–15 years in 44 schools of 24 districts in Taiwan. Spirograms were obtained from 1494 non-asthmatic children. Air pollution data were retrieved from air monitoring stations within one kilometre of the schools. Using three-level hierarchical linear models, individual lung function was fitted to air pollution, with adjustments for demographics, indoor exposures, outdoor activity, and districts. Results Lung function changes per inter-quartile increase of the past two-months average levels of particulate matter <2.5 ?m (PM2.5) and ozone (12 ?g/m3, 32–44 and 6.7 ppb, 32–38, respectively) were ?103 and ?142 ml on FVC, ?86 and ?131 on FEV1, and ?102 and ?188 ml/s on MMEF, respectively. Lag-1-day ozone exposure was associated with decreased MMEF. In children aged 6–10, PM2.5 was associated with decreased FEV1/FVC and MMEF/FVC ratios. Conclusions In children aged 6–15 years, sub-chronic exposure to ambient PM2.5 and ozone leads to reduced lung capacity, whereas acute exposure to ozone decreases mid-expiratory flow. In children aged 6–10 years, additional airway obstructive patterns in lung function may be associated with PM2.5 exposure.

Great Smoky Mountains Project (GSMP) Great Smoky Mountains Project (GSMP) Background Fine particle annual mass concentrations in the Tennessee Valley range from 14 to20 micrograms per cubic meter. All seven urban/suburban sites exceeded the annual PM2.5 standard; only the rural Lawrence County TN site remained below the 15 µg/m3 annual standard. None of the stations exceeded the 65 µg/m3 level of the 24-hour PM2.5 standard. Summer high-winter low seasonality is evident. The current FRM PM2.5 mass measurements under-estimate the contribution of volatile/semi-volatile nitrates and organic carbon species. The semi-volatile organic fraction is both highly variable and significant, and assessments of semi-volatile and non-volatile organic carbon fractions are needed when particle composition measurements are made, especially at urban sites.

Westinghouse Hanford Company operational environmental monitoring annual report, calendar year 1994  

SciTech Connect (OSTI)

This document presents the results of the Westinghouse Hanford Company near-facility operational environmental monitoring for 1994 in the 100, 200/600, and 300/400 Areas of the Hanford Site, in south-central Washington State. Surveillance activities included sampling and analyses of ambient air surface water, groundwater, soil, sediments, and biota. Also, external radiation measurements and radiological surveys were taken at waste disposal sites, radiologically controlled areas, and roads. These activities were conducted to assess and control the effects of nuclear facilities and waste sites on the local environment. In addition, diffuse sources were monitored to determine compliance with Federal, State, and/or local regulations. In general, although effects from nuclear facilities are still seen on the Hanford Site and radiation levels are slightly elevated when compared to offsite locations, the differences are less than in previous years.

Breaking wind waves as a source of ambient noise  

Science Journals Connector (OSTI)

A theoretical model for the prediction of ambient noise level due to collective oscillations of air bubbles under breaking wind waves is presented. The model uses a budget of the energy flux from the breaking waves to quantify acoustic power radiation by a bubble cloud. A shift of the noise spectra to lower frequency due to collective bubble oscillation is assumed. The model derives good estimates of the magnitude slope and frequency range of the noise spectra using the wind speed or height of breaking waves.

Hanford Site near-facility environmental monitoring annual report, calendar year 1997  

SciTech Connect (OSTI)

Near-facility environmental monitoring provides a means to measure the impacts of operations, waste management, and remediation activities on the environment adjacent to facilities and ensure compliance with local, state, and federal environmental regulations. Specifically, near-facility environmental monitoring monitors new and existing sites, processes, and facilities for potential impacts and releases; fugitive emissions and diffuse sources associated with contaminated areas, facilities (both active and those undergoing surveillance and maintenance), and environmental restoration activities. External radiation, ambient air particulates, ground and surface water, soil, sediment, and biota (plants and animals) are sampled or monitored. Parameters include, as appropriate, radionuclides; radiation fields; chemical or physical constituents, such as nitrates; pH; and water temperature. All ambient air results were below the US Department of Energy (DOE) Derived Concentration Guides (DCGs). Groundwater concentrations at the two wells at the 107-N Facility were below both the DOE DCG and US Environmental Protection Agency Interim Drinking Water Standards for gamma emitting radionuclides. Soil and vegetation results were generally within historic ranges and mostly below the Accessible Soil Concentration limits (included in HNF-PRO-454, Inactive Waste Sites) with the exception of one soil sampling location at 1 00 N Area. External radiation fields continued an overall downward trend. Surface water disposal unit samples (water, sediment, and aquatic vegetation) showed radionuclide concentrations below their respective DCG and Accessible Soil Concentration limits. The 100 N Area Columbia river shoreline springs results were below DCGs with the exception of one Sr concentration. More than 4,600 ha (11,300 acres) of radiologically controlled areas were surveyed in 1997, approximately the same as in 1996.

CEMs turn monitoring giant  

SciTech Connect (OSTI)

Crucial to complying with environmental regulations is selecting appropriate pollution control equipment to capture or destroy regulated pollutants. But just as important is selecting a continuous emissions monitoring system (CEM). CEMs play a dual role in an overall compliance strategy. On one hand, they identify the type and quantity of emissions at a source as a first step for determining which regulatory requirements and control technologies are applicable. They also provide ongoing emissions data to demonstrate compliance with air and other environmental regulations. Facilities are required to monitor their processes with CEMs, or a comparable technology, under several titles of the Clean Air Act Amendments of 1990. CEMs meet regulatory requirements if they include a SO[sub 2] concentration monitor, nitrogen oxides (NO[sub x]) concentration monitor, volumetric flow monitor, opacity monitor, diluent gas monitor and data acquisition and handling system. The entire system and each subsystem has to be installed and certified before it can be used for compliance. A written quality assurance/quality control (QA/QC) plan for the CEMs must accompany the permit application. The acid rain rules also impose performance standards and frequent calibration checks to ensure the integrity of CEMs data.

Impact of aircraft emissions on air quality in the vicinity of airports. Volume II. An updated model assessment of aircraft generated air pollution at LAX, JFK, and ORD. Final report Jan 1978-Jul 1980  

SciTech Connect (OSTI)

This report documents the results of the Federal Aviation Administration (FAA)/Environmental Protection Agency (EPA) air quality study which has been conducted to assess the impact of aircraft emissions of carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx) in the vicinity of airports. This assessment includes the results of recent modeling and monitoring efforts at Washington National (DCA), Los Angeles International (LAX), Dulles International (IAD), and Lakeland, Florida airports and an updated modeling of aircraft generated pollution at LAX, John F. Kennedy (JFK) and Chicago O'Hare (ORD) airports. The Airport Vicinity Air Pollution (AVAP) model which was designed for use at civil airports was used in this assessment. In addition the results of the application of the military version of the AVAP model the Air Quality Assessment Model (AQAM), are summarized. Both the results of the pollution monitoring analyses in Volume I and the modeling studies in Volume II suggest that: maximum hourly average CO concentrations from aircraft are unlikely to exceed 5 parts per million (ppm) in areas of public exposure and are thus small in comparison to the National Ambient Air Quality Standard of 35 ppm; maximum hourly HC concentrations from aircraft can exceed 0.25 ppm over an area several times the size of the airport; and annual average NO2 concentrations from aircraft are estimated to contribute only 10 to 20 percent of the NAAQS limit level.

Air Pollution  

Science Journals Connector (OSTI)

Both natural processes and human activities contribute to air pollution, with the combustion of fossil fuels being the largest anthropogenic source of air pollutants. Adverse health effects (above all respiratory and cardiovascular complications), damage to crops, natural vegetation and materials, reduced visibility and changed radiation balance of the atmosphere are the major consequences of high concentrations of air pollutants. Technical fixes can sharply reduce emissions from large stationary sources and lower the rates of automotive emissions, but the rising number of vehicles and longer time spent on the road will call for more radical solutions to traffic-generated photochemical smog now present in all major urban areas.

Toward Distinguishing Woodsmoke and Diesel Exhaust in Ambient Particulate Matter  

SciTech Connect (OSTI)

Particulate matter (PM) from biomass burning and diesel exhaust has distinct X-ray spectroscopic, carbon specific signatures, which can be employed for source apportionment. Characterization of the functional groups of a wide selection of PM samples (woodsmoke, diesel soot, urban air PM) was carried out using the soft X-ray spectroscopy capabilities at the synchrotron radiation sources in Berkeley (ALS) and Brookhaven (NSLS). The spectra reveal that diesel exhaust particulate (DEP) matter is made up from a semigraphitic solid core and soluble organic matter, predominantly with carboxylic functional groups. Woodsmoke PM has no or a less prevalent, graphitic signature, instead it contains carbon-hydroxyl groups. Using these features to apportion the carbonaceous PM in ambient samples we estimate that the relative contribution of DEP to ambient PM in an urban area such as Lexington, KY and St. Louis, MO is 7% and 13.5%, respectively. These values are comparable to dispersion modeling data from nonurban and urban areas in California, and with elemental carbon measurements in urban locations such as Boston, MA, Rochester, NY, and Washington, DC.

Modal parameter extraction from large operating structures using ambient excitation  

SciTech Connect (OSTI)

A technique called the Natural Excitation Technique or has been developed to response extract response parameters from large operational structure when subjected to random and unmeasured forces such as wind, road noise, aerodynamics, or waves. Six applications of NExT to ambient excitation testing and NExT analysis are surveyed in this paper with a minimum of technical detail. In the first application, NExT was applied to a controlled-yaw Horizontal-Axis Wind Turbine (HAWT). By controlling the yaw degree of freedom an important class of rotating coordinate system effects are reduced. A new shape extraction procedure was applied to this data set with good results. The second application was to a free-yaw HAWT. The complexity of the response has prompted further analytical studies and the development of a specialized visualization package. The third application of NExT was to a parked three-bladed Vertical-Axis Wind Turbine (VAWT) in which traditional modal testing could not excite all modes of interest. The shape extraction process used cross-correlation functions directly in a time-domain shape-fitting routine. The fourth application was to ground transportation systems. Ongoing work to improve driver and passenger comfort in tractor-trailer vehicles and to refine automobile body and tire models will use NExT. NExT has been used to process ambient vibration data for Finite Element Model correlation and is being used to study Structural Health Monitoring with ambient excitation. Shape fitting was performed using amplitude and phase information taken directly from the cross-spectra. The final application is to an offshore structure. This work is on-going, however initial studies have found a high-modal density, high noise content, and sparse data set.

Environmental monitoring at the Lawrence Livermore National Laboratory: 1986 annual report  

SciTech Connect (OSTI)

This report documents the results of the environmental monitoring program at the Lawrence Livermore National Laboratory (LLNL) for 1986. To evaluate the effect of LLNL operations on the local environment, measurements of direct radiation and a variety of radionuclides and chemical pollutants in ambient air, soil, surface water, groundwater, vegetation, milk, foodstuff, and sewage effluents were made at both the Livermore site and nearby Site 300. This report was prepared to meet the requirements of DOE Order 5484.1. Evaluations are made of LLNL's compliance with all applicable guides, standards, and limits for radiological and nonradiological releases to the environment. The data indicate that no releases in excess of the applicable standards were made during 1986, and that LLNL operations had no adverse environmental impact.

Modeling of coupled thermodynamic and geomechanical performance of underground compressed air energy storage (CAES) in lined rock caverns  

SciTech Connect (OSTI)

We applied coupled nonisothermal, multiphase fluid flow and geomechanical numerical modeling to study the coupled thermodynamic and geomechanical performance of underground compressed air energy storage (CAES) in concrete-lined rock caverns. The paper focuses on CAES in lined caverns at relatively shallow depth (e.g., 100 m depth) in which a typical CAES operational pressure of 5 to 8 MPa is significantly higher than both ambient fluid pressure and in situ stress. We simulated a storage operation that included cyclic compression and decompression of air in the cavern, and investigated how pressure, temperature and stress evolve over several months of operation. We analyzed two different lining options, both with a 50 cm thick low permeability concrete lining, but in one case with an internal synthetic seal such as steel or rubber. For our simulated CAES system, the thermodynamic analysis showed that 96.7% of the energy injected during compression could be recovered during subsequent decompression, while 3.3% of the energy was lost by heat conduction to the surrounding media. Our geomechanical analysis showed that tensile effective stresses as high as 8 MPa could develop in the lining as a result of the air pressure exerted on the inner surface of the lining, whereas thermal stresses were relatively smaller and compressive. With the option of an internal synthetic seal, the maximum effective tensile stress was reduced from 8 to 5 MPa, but was still in substantial tension. We performed one simulation in which the tensile tangential stresses resulted in radial cracks and air leakage though the lining. This air leakage, however, was minor (about 0.16% of the air mass loss from one daily compression) in terms of CAES operational efficiency, and did not significantly impact the overall energy balance of the system. However, despite being minor in terms of energy balance, the air leakage resulted in a distinct pressure increase in the surrounding rock that could be quickly detected using pressure monitoring outside the concrete lining.

Scrubbing of contaminants from contaminated air streams with aerogel materials with optional photocatalytic destruction  

SciTech Connect (OSTI)

Disclosed is a method for separating a vaporous or gaseous contaminant from an air stream contaminated therewith. This method includes the steps of: (a) passing said contaminated air into a contact zone in which is disposed an aerogel material capable of selecting adsorbing said contaminant from air and therein contacting said contaminated air with an aerogel material; and (b) withdrawing from said zone, air depleted of said contaminant. For present purposes, "contaminant" means a material not naturally occurring in ambient air and/or a material naturally occurring in air but present at a concentration above that found in ambient air. Thus, the present invention scrubs (or treats) air for the purpose of returning it to its ambient composition. Also disclosed herein is a process for the photocatalytic destruction of contaminants from an air stream wherein the contaminated air stream is passed into a control cell or contact zone in which is disposed a photocatalytic aerogel and exposing said aerogel to ultraviolet (UV) radiation for photocatalytically destroying the adsorbed contaminant, and withdrawing from said cell an exhaust air stream depleted in said contaminant.

Method and apparatus for reducing cold-phase emissions by utilizing oxygen-enriched intake air  

DOE Patents [OSTI]

An oxygen-enriched air intake control system for an internal combustion engine includes air directing apparatus to control the air flow into the intake of the engine. During normal operation of the engine, ambient air flowing from an air filter of the engine flows through the air directing apparatus into the intake of the engine. In order to decrease the amount of carbon monoxide (CO) and hydrocarbon (HC) emissions that tend to be produced by the engine during a short period of time after the engine is started, the air directing apparatus diverts for a short period of time following the start up of the engine at least a portion of the ambient air from the air filter through a secondary path. The secondary path includes a selectively permeable membrane through which the diverted portion of the ambient air flows. The selectively permeable membrane separates nitrogen and oxygen from the diverted air so that oxygen enriched air containing from about 23% to 25% oxygen by volume is supplied to the intake of the engine.

Air Leakage and Air Transfer Between Garage and Living Space  

SciTech Connect (OSTI)

This research project focused on evaluation of air transfer between the garage and living space in a single-family detached home constructed by a production homebuilder in compliance with the 2009 International Residential Code and the 2009 International Energy Conservation Code. The project gathered important information about the performance of whole-building ventilation systems and garage ventilation systems as they relate to minimizing flow of contaminated air from garage to living space. A series of 25 multi-point fan pressurization tests and additional zone pressure diagnostic testing characterized the garage and house air leakage, the garage-to-house air leakage, and garage and house pressure relationships to each other and to outdoors using automated fan pressurization and pressure monitoring techniques. While the relative characteristics of this house may not represent the entire population of new construction configurations and air tightness levels (house and garage) throughout the country, the technical approach was conservative and should reasonably extend the usefulness of the results to a large spectrum of house configurations from this set of parametric tests in this one house. Based on the results of this testing, the two-step garage-to-house air leakage test protocol described above is recommended where whole-house exhaust ventilation is employed. For houses employing whole-house supply ventilation (positive pressure) or balanced ventilation (same pressure effect as the Baseline condition), adherence to the EPA Indoor airPLUS house-to-garage air sealing requirements should be sufficient to expect little to no garage-to-house air transfer.

Ion Monitoring  

DOE Patents [OSTI]

The apparatus and method provide a technique for significantly reducing capacitance effects in detector electrodes arising due to movement of the instrument relative to the item/location being monitored in ion detection based techniques. The capacitance variations are rendered less significant by placing an electrically conducting element between the detector electrodes and the monitored location/item. Improved sensitivity and reduced noise signals arise as a result. The technique also provides apparatus and method suitable for monitoring elongate items which are unsuited to complete enclosure in one go within a chamber. The items are monitored part by part as the pass through the instrument, so increasing the range of items or locations which can be successfully monitored.

Ambient air samples were taken at two locations in the East Mountain Area in conjunction with thermal testing at the Lurance Canyon Burn Site (LCBS). The samples were taken to provide measurements of particulate matter with a diameter less than or equal to 10 micrometers (PM{sub 10}) and volatile organic compounds (VOCs). This report summarizes the results of the sampling performed in 1995. The results from small-scale testing performed to determine the potentially produced air pollutants in the thermal tests are included in this report. Analytical results indicate few samples produced measurable concentrations of pollutants believed to be produced by thermal testing. Recommendations for future air sampling in the East Mountain Area are also noted.

Object detectability at increased ambient lighting conditions  

SciTech Connect (OSTI)

Under typical dark conditions encountered in diagnostic reading rooms, a reader's pupils will contract and dilate as the visual focus intermittently shifts between the high luminance display and the darker background wall, resulting in increased visual fatigue and the degradation of diagnostic performance. A controlled increase of ambient lighting may, however, reduce the severity of these pupillary adjustments by minimizing the difference between the luminance level to which the eyes adapt while viewing an image (L{sub adp}) and the luminance level of diffusely reflected light from the area surrounding the display (L{sub s}). Although ambient lighting in reading rooms has conventionally been kept at a minimum to maintain the perceived contrast of film images, proper Digital Imaging and Communications in Medicine (DICOM) calibration of modern medical-grade liquid crystal displays can compensate for minor lighting increases with very little loss of image contrast. This paper describes two psychophysical studies developed to evaluate and refine optimum reading room ambient lighting conditions through the use of observational tasks intended to simulate real clinical practices. The first study utilized the biologic contrast response of the human visual system to determine a range of representative L{sub adp} values for typical medical images. Readers identified low contrast horizontal objects in circular foregrounds of uniform luminance (5, 12, 20, and 30 cd/m{sup 2}) embedded within digitized mammograms. The second study examined the effect of increased ambient lighting on the detection of subtle objects embedded in circular foregrounds of uniform luminance (5, 12, and 35 cd/m{sup 2}) centered within a constant background of 12 cd/m{sup 2} luminance. The images were displayed under a dark room condition (1 lux) and an increased ambient lighting level (50 lux) such that the luminance level of the diffusely reflected light from the background wall was approximately equal to the image L{sub adp} value of 12 cd/m{sup 2}. Results from the first study demonstrated that observer true positive and false positive detection rates and true positive detection times were considerably better while viewing foregrounds at 12 and 20 cd/m{sup 2} than at the other foreground luminance levels. Results from the second study revealed that under increased room illuminance, the average true positive detection rate improved a statistically significant amount from 39.3% to 55.6% at 5 cd/m{sup 2} foreground luminance. Additionally, the true positive rate increased from 46.4% to 56.6% at 35 cd/m{sup 2} foreground luminance, and decreased slightly from 90.2% to 87.5% at 12 cd/m{sup 2} foreground luminance. False positive rates at all foreground luminance levels remained approximately constant with increased ambient lighting. Furthermore, under increased room illuminance, true positive detection times declined at every foreground luminance level, with the most considerable decrease (approximately 500 ms) at the 5 cd/m{sup 2} foreground luminance. The first study suggests that L{sub adp} of typical mammograms lies between 12 and 20 cd/m{sup 2}, leading to an optimum reading room illuminance of approximately 50-80 lux. Findings from the second study provide psychophysical evidence that ambient lighting may be increased to a level within this range, potentially improving radiologist comfort, without deleterious effects on diagnostic performance.

We describe a small, inexpensive portable monitor for airborne particulates, composed of the following elements: a. A simple size-selective inlet (vertical elutriator) that permits only particles below a pre-set diameter to pass and enter the measurement section; b. A measurement section in which passing particles are deposited thermophoretically on a micro-fabricated resonant piezoelectric mass sensor; c. An optical characterization module co-located with the mass sensor module that directs infrared and ultraviolet beams through the deposit. The emergent optical beams are detected by a photodiode. The optical absorption of the deposit can be measured in order to characterize the deposit, and determine how much is due to diesel exhaust and/or environmental tobacco smoke; and d. A small pump that moves air through the device, which may also be operated in a passive mode. The component modules were designed by the project team, and fabricated at UCB andLBNL. Testing and validation were performed in a room-sized environmental chamber at LBNL in to which was added either environmental tobacco smoke (ETS, produced by a cigarette smoking machine) or diesel exhaust (from a conventional diesel engine). Two pilot field tests in a dwelling compared the monitor with existing aerosol instruments during exposure to infiltrated ambient air to which cigarette smoke, diesel exhaust, wood smoke and cooking fumes were added. The limit of detection (LOD) derived from statistical analysis of field data is 18 mu g m-3, at the 99percent confidence level. The monitor weighs less than 120 g and has a volume of roughly 250 cm3. Power consumption is approximately 100 milliwatts. During this study, the optical component of the device was not fully implemented and has been left for future efforts. Suggested improvements in the current prototype include use of integrated thermal correction, reconfiguration of the resonator for increased particle collection area, increased thermophoretic collection efficiency using an increased temperature gradient, and shielding the resonator electronics from deposition of ultrafine particles.

Air Leakage of Furnaces and Air Handlers Air Leakage of Furnaces and Air Handlers Title Air Leakage of Furnaces and Air Handlers Publication Type Journal Article LBNL Report Number LBNL-5553E Year of Publication 2010 Authors Walker, Iain S., Mile Lubliner, Darryl J. Dickerhoff, and William W. Delp Journal 2010 ACEEE Summer Study on Energy Efficiency in Buildings The Climate for efficiency is now Date Published 08/2010 Abstract In recent years, great strides have been made in reducing air leakage in residential and to a lesser extent small commercial forced air duct systems. Several authorities have introduced low leakage limits for thermal distribution systems; for example, the State of California Energy Code for Buildings gives credit for systems that leak less than 6% of the total air flow at 25 Pa.

High Energy Efficiency Air Conditioning  

SciTech Connect (OSTI)

This project determined the performance of a new high efficiency refrigerant, Ikon B, in a residential air conditioner designed to use R-22. The refrigerant R-22, used in residential and small commercial air conditioners, is being phased out of production in developed countries beginning this year because of concerns regarding its ozone depletion potential. Although a replacement refrigerant, R-410A, is available, it operates at much higher pressure than R-22 and requires new equipment. R-22 air conditioners will continue to be in use for many years to come. Air conditioning is a large part of expensive summer peak power use in many parts of the U.S. Previous testing and computer simulations of Ikon B indicated that it would have 20 - 25% higher coefficient of performance (COP, the amount of cooling obtained per energy used) than R-22 in an air-cooled air conditioner. In this project, a typical new R-22 residential air conditioner was obtained, installed in a large environmental chamber, instrumented, and run both with its original charge of R-22 and then with Ikon B. In the environmental chamber, controlled temperature and humidity could be maintained to obtain repeatable and comparable energy use results. Tests with Ikon B included runs with and without a power controller, and an extended run for several months with subsequent analyses to check compatibility of Ikon B with the air conditioner materials and lubricant. Baseline energy use of the air conditioner with its original R-22 charge was measured at 90 deg F and 100 deg F. After changeover to Ikon B and a larger expansion orifice, energy use was measured at 90 deg F and 100 deg F. Ikon B proved to have about 19% higher COP at 90 deg F and about 26% higher COP at 100 deg F versus R-22. Ikon B had about 20% lower cooling capacity at 90 deg F and about 17% lower cooling capacity at 100 deg F versus R-22 in this system. All results over multiple runs were within 1% relative standard deviation (RSD). All of these values agree well with previous results and computer simulations of Ikon B performance versus R-22. The lower cooling capacity of Ikon B is not a concern unless a particular air conditioner is near its maximum cooling capacity in application. Typically, oversized A/C systems are installed by contractors to cover contingencies. In the extended run with Ikon B, which lasted about 4.5 months at 100 deg F ambient temperature and 68% compressor on time, the air conditioner performed well with no significant loss of energy efficiency. Post-run analysis of the refrigerant, compressor lubricant oil, compressor, compressor outlet tubing, and the filter/dryer showed minor effects but nothing that was considered significant. The project was very successful. All objectives were achieved, and the performance of Ikon B indicates that it can easily be retrofitted into R-22 air conditioners to give 15 - 20% energy savings and a 1 - 3 year payback of retrofit costs depending on location and use. Ikon B has the potential to be a successful commercial product.

PDSF Monitoring PDSF Monitoring The plot below is a measure of the read and write rates a single user would experience via the PDSF batch system. Jobs are submitted sequentially every hour to the debug queue. If a jobs doesn't finish in 8 minutes, it is killed and a -1 rate is written out. The read rates are calculated by copying a directory containing 2 files totaling 274 MB from the eliza directories to the $TMPDIR on the node running the job. The write rates are calculated by untarring a tarball on the eliza directories. The write rates are typically around a factor of two slower than the read rates, because the data still has to travel to the compute node and then back to the eliza for writing. The I/O rates are taken from the ganglia monitoring and serve as a measure of the amount of

Idaho National Laboratory Site Environmental Monitoring Plan  

SciTech Connect (OSTI)

This plan provides a high-level summary of environmental monitoring performed by various organizations within and around the Idaho National Laboratory (INL) Site as required by U.S. Department of Energy (DOE) Order 435.1, Radioactive Waste Management, and DOE Order 458.1, Radiation Protection of the Public and the Environment, Guide DOE/EH-0173T, Environmental Regulatory Guide for Radiological Effluent Monitoring and Environmental Surveillance, and in accordance with 40 Code of Federal Regulations (CFR) 61, National Emission Standards for Hazardous Air Pollutants. The purpose of these orders is to 1) implement sound stewardship practices that protect the air, water, land, and other natural and cultural resources that may be impacted by DOE operations, and 2) to establish standards and requirements for the operations of DOE and DOE contractors with respect to protection of the environment and members of the public against undue risk from radiation. This plan describes the organizations responsible for conducting environmental monitoring across the INL Site, the rationale for monitoring, the types of media being monitored, where the monitoring is conducted, and where monitoring results can be obtained. Detailed monitoring procedures, program plans, or other governing documents used by contractors or agencies to implement requirements are referenced in this plan. This plan covers all planned monitoring and environmental surveillance. Nonroutine activities such as special research studies and characterization of individual sites for environmental restoration are outside the scope of this plan.

Infrasonic ambient ocean noise: Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Measurements of ocean ambient noise were made at three widely separated deep?water bottom locations in the N. E. Pacific at eight frequencies in the range from 2.5–20.0 Hz for 40 consecutive days. Concurrent data on wind speed and wave height were collected. Analysis indicates that the spectrum level of infrasonicnoise is linearly related to the log of the wind speed above a threshold level. There is evidence that the noise can be directly associated with the wind rather than through the surface waves it produces. [Work supported by ONR.

Ambient noise levels and reverberation times in Mississippi school rooms  

Science Journals Connector (OSTI)

Nine elementary school classrooms at three Mississippi public schools were selected at random for noise and reverberation time measures to monitor voluntary compliance with ANSI standard S12.60-2002 (Acoustical Performance Criteria Design Requirements and Guidelines for Schools). One-hour equivalent dBA noise levels and reverberation times (T60) were measured with SpectraPLUS Version 5.0 software. Measures were taken on separate days at each school in unoccupied classrooms with the HVAC system operating. For ambient noise measures an Audix TR40 omnidirectional microphone was placed in a 12 inch stand on a student's desk near the middle of the room and oriented toward the teacher's desk at a 45 degree angle. For the reverberation time measure a 400 watt loudspeaker (Yamaha BR15M) was placed on the teacher's desk about 3 meters from the microphone. Results showed that noise levels varied from 28 dBA to 51 dBA with broad spectra containing peaks at 120 Hz and harmonics. Five of nine classrooms had noise levels that exceeded the ANSI recommended level of 35 dBA. Reverberation times varied from .21 to .62 seconds; only one classroom exceeded the recommended minimal reverberation time of .6 seconds. Acoustical modifications to reduce noise levels and reverberation times will be addressed.

A system is described for continuously monitoring the concentration of tritium in an aqueous stream. The system pumps a sample of the stream to magnesium-filled combustion tube which reduces the sample to extract hydrogen gas. The hydrogen gas is then sent to an isotope separation device where it is separated into two groups of isotopes: a first group of isotopes containing concentrations of deuterium and tritium, and a second group of isotopes having substantially no deuterium and tritium. The first group of isotopes containing concentrations of deuterium and tritium is then passed through a tritium detector that produces an output proportional to the concentration of tritium detected. Preferably, the detection system also includes the necessary automation and data collection equipment and instrumentation for continuously monitoring an aqueous stream. 1 fig.

The selected remedy for AOC FTA-2/LF-2 is Biosparging with Ambient Air Monitoring. This remedial action is a source control action that addresses leaching of organic compounds to groundwater, the principal known threat at AOC FTA-2/LF-2. It consists of designing, constructing, and operating a biosparging treatment system, maintaining institutional controls, and five-year reviews of remedy protectiveness. The remedy reduces the release of contaminants from subsurface soils by treating subsurface soils to meet protective cleanup levels.

Measurement of particulate densities in air  

Science Journals Connector (OSTI)

Clean air is one of the most important issues that govern the health of all live forms. However presently there are not many quick and simple methods for measuring impurities like particulates in air. These impurities have an enormous diversity in their physical and chemical structure. They may be unburned carbon particles from a diesel engine exhaust and chimney pollen grains in the spring air or asbestos in a factory. This paper shows that changes in the composition of the air cause a change in the speed of sound. Therefore by measuring the change in the speed of sound it is possible to monitor the density of particulates in the air. Preliminary tests are conducted on various smoke–air mixtures. The results demonstrate that this methodology is very sensitive to any changes in the composition of the air. Its implementation is very simple and efficient and costs much less than the conventional method currently used in the auto industry. This technique will be used to calculate the mass density of the particulates resulting from a diesel engine and results thus obtained will be compared with those calculated using other methods.

THE LIFETIME OF AEROSOLS IN AMBIENT AIR: CONSIDERATION OF THE EFFECTS OF SURFACTANTS AND CHEMICAL REACTIONS  

SciTech Connect (OSTI)

The relatively long lifetime of droplets in atmospheric haze and fog in comparison with similar droplets of pure water is attributed to the presence of a monolayer of surfactant film and to the accumulation Of soluble salts from chemical reactions. The lifetime of these droplets is a significant factor in the evaluation of the role of heterogeneous aqueous chemical reactions occurring in the troposphere. Several mechanisms of SO{sub 2} oxidation in the presence of liquid water are investigated. It is shown that soot-catalyzed oxidation of sulfur dioxide could be responsible for the high level of sulfate concentration observed in the coastal industrial areas.

An empirical analysis of exposure-based regulation to abate toxic air pollution  

SciTech Connect (OSTI)

Title III of the 1990 Clean Air Act Amendments requires the Environmental Protection Agency to regulate 189 air toxics, including emissions from by-product coke ovens. Economists criticize the inefficiency of uniform standards, but Title III makes no provision for flexible regulatory instruments. Environmental health scientists suggest that population exposure, not necessarily ambient air quality, should motivate environmental air pollution policies. Using an engineering-economic model of the United States steel industry, we estimate that an exposure-based policy can achieve the same level of public health as coke oven emissions standards and can reduce compliance costs by up to 60.0%. 18 refs., 3 figs., 1 tab.

High-Performance Sorbents for Carbon Dioxide Capture from Air  

SciTech Connect (OSTI)

This project has focused on capture of CO{sub 2} from ambient airair capture”). If this process is technically and economically feasible, it could potentially contribute to net reduction of CO{sub 2} emissions in ways that are complementary to better developed techniques for CO{sub 2} from concentrated point sources. We focused on cyclic adsorption processes for CO{sub 2} capture from air in which the entire cycle is performed at moderate temperatures. The project involved both experimental studies of sorbent materials and process level modeling of cyclic air capture processes. In our experimental work, a series of amine-functionalized silica adsorbents were prepared and characterized to determine the impact of molecular architecture on CO{sub 2} capture. Some key findings were: • Amine functionalized silicas can be prepared with high enough CO{sub 2} capacities under ambient conditions to merit consideration for use in air capture processes. • Primary amines are better candidates for CO{sub 2} capture than secondary or tertiary amines, both in terms of amine efficiency for CO{sub 2} adsorption and enhanced water affinity. • Mechanistic understanding of degradation of these materials can enable control of molecular architecture to significantly improve material stability. Our process modeling work provided the first publically available cost and energy estimates for cyclic adsorption processes for air capture of CO{sub 2}. Some key findings were: • Cycles based on diurnal ambient heating and cooling cannot yield useful purities or amounts of captured CO{sub 2}. • Cycles based on steam desorption at 110 oC can yield CO{sub 2} purities of ~88%. • The energy requirements for cycles using steam desorption are dominated by needs for thermal input, which results in lower costs than energy input in the form of electricity. Cyclic processes with operational costs of less than $100 tCO{sub 2}-net were described, and these results point to process and material improvements that could substantially reduce these costs. The most critical conclusions from our work are that (i) CO{sub 2} capture from ambient air using moderate temperature cyclic adsorption processes is technically feasible and (ii) the operational costs of realistic versions of these processes are moderate enough to encourage future development of this technology. Because of the very modest net investment that has been made in R&D associated with this approach from all sources worldwide (relative to the massive public and private investment that has been made in technologies for CO{sub 2} from concentrated point sources), our results strongly suggest that continued development of air capture is justified.

Clean Air Interstate Rule (released in AEO2009)  

Reports and Publications (EIA)

Clean Air Interstate Rule (CAIR) is a cap-and-trade program promulgated by the Environmental Protection Agency in 2005, covering 28 eastern U.S. states and the District of Columbia. It was designed to reduce sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions in order to help states meet their National Ambient Air Quality Standards (NAAQS) for ozone and particulate matter (PM2.5) and to further emissions reductions already achieved through the Acid Rain Program and the NOx State Implementation Plan call program. The rule was set to commence in 2009 for seasonal and annual NOx emissions and in 2010 for SO2 emissions.

Monitored Geologic Repository Operations Monitoring and Control System Description Document  

SciTech Connect (OSTI)

The Monitored Geologic Repository Operations Monitoring and Control System provides supervisory control, monitoring, and selected remote control of primary and secondary repository operations. Primary repository operations consist of both surface and subsurface activities relating to high-level waste receipt, preparation, and emplacement. Secondary repository operations consist of support operations for waste handling and treatment, utilities, subsurface construction, and other selected ancillary activities. Remote control of the subsurface emplacement operations, as well as, repository performance confirmation operations are the direct responsibility of the system. In addition, the system monitors parameters such as radiological data, air quality data, fire detection status, meteorological conditions, unauthorized access, and abnormal operating conditions, to ensure a safe workplace for personnel. Parameters are displayed in a real-time manner to human operators regarding surface and subsurface conditions. The system performs supervisory monitoring and control for both important to safety and non-safety systems. The system provides repository operational information, alarm capability, and human operator response messages during emergency response situations. The system also includes logic control to place equipment, systems, and utilities in a safe operational mode or complete shutdown during emergency response situations. The system initiates alarms and provides operational data to enable appropriate actions at the local level in support of emergency response, radiological protection response, evacuation, and underground rescue. The system provides data communications, data processing, managerial reports, data storage, and data analysis. This system's primary surface and subsurface operator consoles, for both supervisory and remote control activities, will be located in a Central Control Center (CCC) inside one of the surface facility buildings. The system consists of instrument and control equipment and components necessary to provide human operators with sufficient information to monitor and control the operation of the repository in an efficient and safe manner. The system consists of operator consoles and workstations, multiple video display terminals, communications and interfacing equipment, and instrument and control software with customized configuration to meet the needs of the Monitored Geologic Repository (MGR). Process and logic controllers and the associated input/output units of each system interfaced with this system will be configured into Remote Terminal Units (RTU) and located close to the systems to be monitored and controlled. The RTUs are configured to remain operational should communication with CCC operations be lost. The system provides closed circuit television to selectively view systems, operations, and equipment areas and to aid in the operation of mechanical systems. Control and monitoring of site utility systems will be located in the CCC. Site utilities include heating, ventilation, and air conditioning equipment; plant compressed air; plant water; firewater; electrical systems; and inert gases, such as nitrogen, if required. This system interfaces with surface and subsurface systems that either generate output data or require remote control input. The system interfaces with the Site Communications System for bulk storage of operational data, on-site and off-site communication, and a plant-wide public announcement system. The system interfaces with the Safeguards and Security System to provide operational status and emergency alarm indications. The system interfaces with the Site Operation System to provide site wide acquisition of data for analysis and reports, historical information for trends, utility information for plant operation, and to receive operating plans and procedures.

Outdoor air pollution and term low birth weight in Japan  

Science Journals Connector (OSTI)

AbstractIntroduction Evidence has accumulated on the association between ambient air pollution and adverse birth outcomes. However, most of the previous studies were conducted in geographically distinct areas and suffer from lack of important potential covariates. We examined the effect of ambient air pollution on term low birth weight (LBW) using data from a nationwide population-based longitudinal survey in Japan that began in 2001. Methods We restricted participants to term singletons (n = 44,109). Air pollution concentrations during the 9 months before birth were obtained at the municipality level and were assigned to the participants who were born in the corresponding municipality. We conducted multilevel logistic regression analyses adjusting for individual and municipality-level variables. Results We found that air pollution exposure during pregnancy was positively associated with the risk of term LBW. In the fully adjusted models, odds ratios following one interquartile range increase in each pollutant were 1.09 (95% confidence interval: 1.00, 1.19) for suspended particulate matter (SPM), 1.11 (0.99, 1.26) for nitrogen dioxide (NO2), and 1.71 (1.18, 2.46) for sulfur dioxide (SO2). Specifically, effect estimates for SPM and NO2 exposure at the first trimester were higher than those at other trimesters, while SO2 was associated with the risk at all trimesters. Nonsmoking mothers were more susceptible to SPM and NO2 exposure compared with smoking mothers. Conclusions Ambient air pollution increases the risk of term LBW in a nationally representative sample in Japan.

Permit compliance monitoring for the power generation industry  

SciTech Connect (OSTI)

The Clean Air Act Amendments (CAAA) of 1990 authorized EPA to develop regulations requiring facilities to monitor the adequacy of emission control equipment and plant operations. Furthermore, under the CAAA, EPA is required to issue regulations to require owners and operators of large industrial facilities to enhance air pollution monitoring and certify compliance with air pollution regulations. The fossil-fueled power generation industry has been targeted with the promulgation of the Acid Rain Program regulations of 40 CFR 72, and the Continuous Emissions Monitoring requirements of 40 CFR 75. The Part 75 regulations, with a few exceptions, establish requirements for monitoring, recordkeeping, and reporting of sulfur dioxide, nitrogen oxides, and carbon dioxide emissions, volumetric flow, and opacity data from affected units under the Acid Rain Program. Depending upon the type of unit and location, other applicable emission limitations may apply for particulate emissions (both total and PM-10), carbon monoxide, volatile organic compounds and sulfuric acid mist.

Air transducers with high acoustic impedance  

Science Journals Connector (OSTI)

High?Z air transducers evolved from several industrial transducers. These predecessors include (a) acoustic emission and angle?beam NDT contact transducers; (b) flowmeter transducers for high?pressure methane hot refinery gases and corrosive flare gases; and (c) transducer arrays for monitoring hot corrosive gases flowing at Mach 0.1 in smokestacks of ?3–13 m. This peculiar ancestry accounts for their unusual high?acoustic?impedance construction. By not employing low?Z air?backed radiating membranes transducer bandwidth response time and sensitivity are sacrificed. The solid robust construction however offers some compensating features: tolerance to wide ranges in pressure and temperature including rapid rates of change (thermal shock depressurization); corrosion resistance; operable with standard lab equipment without bias voltage; mounting options where the transducer forms part of the pressure boundary or where it is outside the pressure boundary. Clamp?on air flow applications at one bar include small wind tunnels and plastic pipes. Acoustically isolated pairs measure secondary flow components (crossflow circulation) in a plane perpendicular to the pipe axis. Flow applications include gases such as air mild steam (pending) or other hot pressurized or corrosive fluids. Air?coupled measurements of transmission characteristics of wood or other low?density solids and air?ranging are readily demonstrated with the low?Z transducers.

A dynamic model for air-based photovoltaic thermal systems working under real operating conditions  

Science Journals Connector (OSTI)

Abstract In this paper a dynamic model suitable for simulating real operating conditions of air-based photovoltaic thermal (PVT) systems is presented. The performance of the model is validated by using the operational data collected from the building integrated photovoltaic (PVT) systems installed in two unique buildings. The modelled air outlet temperature and electrical power match very well with the experimental data. In Solar Decathlon house PVT, the average (RMS) error in air outlet temperatures was 4.2%. The average (RMS) error in electrical power was also 4.2%. In the Sustainable Buildings Research Centre PVT, the average errors (RMS) of PV and air temperatures were 3.8% and 2.2%, respectively. The performance of the PVT system under changing working condition is also analysed in this paper. The analysis includes the effect of ambient air temperature, air inlet temperature, air flow rate and solar irradiation on thermal, electrical, first law and second law efficiencies. Both the thermal and the 1st law efficiencies almost linearly increased with the increase of the ambient temperature. However, the PVT electrical efficiency and the second law efficiency decreased with the increase of the ambient temperature. All efficiencies expect the second law efficiency decreased with increase of the PVT air inlet temperature. The second law efficiency first increased and then reduced. With increasing the air flow rate all the efficiencies increased. The electrical and second law efficiencies become less sensitive when the air flow rate exceeded 300 l/s. Both the thermal and the 1st law efficiencies decreased while the electrical efficiency and the second law efficiency increased with the increase of the solar irradiation. The efficiencies found to be very sensitive for low level of solar irradiations. At about 400 W m?2 irradiation efficiencies became less sensitive.

Energy-efficient heat recovery systems for air conditioning of indoor swimming pools  

SciTech Connect (OSTI)

Analysis of a conventional air-conditioning system for indoor swimming pools during the summer season is presented. The analysis showed that the cooling load is characterized by a large latent heat fraction. As a result, a reheating process must be used downstream of the cooling coil to achieve the proper design comfort condition in the pool area. This, in turn, increases the energy requirement per unit cooling load of the pool. Two heat recovery systems are proposed to reduce this energy. In the first system, ambient air is used for the reheating process in an air-to-air heat exchanger. In the second system, mixed air--recirculated and ambient air--is used for the reheating process. Heat recovery efficiency is defined as an index of the energy savings resulting from the use of the heat recovery system compared to that of a conventional air-conditioning system. At a wide range of ambient conditions it is found that the energy savings could be up to 70% of the energy required to operate a conventional air-conditioning system. A parametric study was carried out to size the air-to-air heat exchanger associated with these heat recovery systems, and the results showed that a heat exchanger having an effectiveness of 0.5 would give satisfactory results. The proposed heat recovery systems are also compared to the case of reheating using the heat rejection from the condenser of the refrigeration machine. The comparison showed that the proposed systems save more energy than reheating using the condenser heat. A typical case study is given to demonstrate the savings in energy consumption when these systems are used.

Thin Air Breathing  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Thin Air Breathing Thin Air Breathing Name: Amy Location: N/A Country: N/A Date: N/A Question: Why is it hard to breathe in thin air? What health dangers do mountain climbers face at high altitudes? Replies: Among the obvious dangers of losing ones footing, the oxygen available in the air is considerable less at higher altitudes. If I recall correctly, 21% of the atmosphere at standard temperature and pressure at sea level is composed of oxygen. This is less at higher altitudes. One can lose consciousness and even die in an oxygen deficient environment with changes from oxygen content to lower than 19.5%. This can unfortunate effect can occur within minutes. Dr. Myron The air is not really thin at high altitudes. The problem is that air pressure is lower. As altitude increases, air pressure decreases. In order for your lungs to fill with air, the air pressure in your lungs has to be less than the pressure of the air outside your lungs. Air moves from areas of higher pressure to lower pressure. As your diaphragm (the muscle that separates your chest cavity from your abdominal cavity) moves downward, the size of your chest cavity increases. This decreases the pressure in your chest and air flows in. When the diaphragm is up, it puts pressure on the chest cavity and the pressure in the lungs is greater than outside the lungs. Air flows out. This is an example of Boyle's Law. The movement of the diaphragm is controlled by the brainstem. Anyway-the reason that it is harder for some people to breathe at higher altitudes is that the air pressure differences aren't as great between the inside of the lungs and outside.

Contribution of iceberg sounds to the ambient noise budget in the South Pacific Ocean  

Science Journals Connector (OSTI)

On May 2002 C19 a 5500 km2 iceberg calved from the Ross Ice Shelf eventually drifting eastward into the open Pacific Ocean by 2008. As it sailed into warmer waters thermal and wind stresses caused the iceberg to crack and break apart. These resulting “icequakes” projected wideband acoustic energy into the water column influencing the regional ambient noise environment. Icequake noise was persistent and strong enough to be observed by NOAA’s eastern equatorial Pacific moored hydrophone (EEP-NW at 8N 110W) as well as the hydroacoustic station of International Monitoring System (IMS) on Juan Fernandez Island (H03N at 33.44S 78.91W). Elevated noise levels (maximum of ~+3 dB at NOAA’s EEP and ~+7 dB at IMS H03N hydrophones) were observed by both stations from early 2008 when C19a first appeared in the Pacific until it drifted into the Atlantic Ocean in early 2009. C19a’s icequake and calving activity was also most frequent during this same period. Seasonal changes and long-term trends in ambient noise levels at NOAA’s EEP-NW acoustic mooring (1996–2009) and IMS Juan Fernandez (2003–2010 years) and the unique acoustic role icebergs play in the Southern Ocean will be presented.

Source apportionment of time- and size-resolved ambient particulate matter  

Science Journals Connector (OSTI)

Abstract Size- and time-resolved particulate matter samples collected using eight-stage Davis Rotating-drum Universal-size-cut Monitoring (DRUM) impactors at the Washington-Dulles International Airport were analyzed for the elemental composition using synchrotron X-ray fluorescence. A physically realistic three-way factor analysis model consisting of the outer products of matrices (profiles) times a vector of mass contributions was applied to these data. The problem was solved using a weighted alternating least squares method. Five major emission sources: soil, road salt, aircraft landings, transported secondary sulfate, and local sulfate/construction were identified. The study shows that time- and size-resolved RDI data can assist in the identification of the airport emission sources and atmospheric processes leading to the observed ambient concentrations.

This guide is a resource for understanding the new air leakage requirements in the 2012 IECC and suggestions on how these new measures can be met. It also provides information from Building America's Air Sealing Guide, Best Practices and case studies on homes that are currently meeting the provisions. The 2012 IECC and a few International Residential Code (IRC) requirements are referenced throughout the guide.

Comparison between pressurized design and ambient pressure design of hybrid solid oxide fuel cell–gas turbine systems  

Science Journals Connector (OSTI)

Design performances of the hybrid solid oxide fuel cell (SOFC)–gas turbine (GT) system have been investigated. A pressurized system and an indirectly heated ambient pressure system were analyzed and their performances were compared. In the baseline layout, the basic performance characteristics of the two system configurations were analyzed, with the cell operation temperature and the pressure ratio as the main design parameters. The pressurized system exhibits a better efficiency owing to not only the higher cell voltage but also more effective utilization of gas turbine, i.e., a larger GT power contribution due to a higher turbine inlet temperature. Independent setting of the turbine inlet temperature was simulated by using the additional fuel supply as well as the air bypass. Increasing the pressure ratio of the gas turbine hardly improves the system efficiency, but the efficiency becomes less sensitive to the turbine inlet temperature. In the ambient pressure system, the available design parameter range is much reduced due to the limit on the recuperator temperature. In particular, design of the ambient pressure hybrid system with a gas turbine of a high pressure ratio does not seem quite feasible because the system efficiency that can be achieved at the possible design conditions is even lower than the efficiency of the SOFC only system.

Characterization of CdZnTe ambient temperature detectors  

SciTech Connect (OSTI)

A great deal of interest has been generated in the use of cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) detectors for ambient temperature detection of radionuclides. The addition of zinc to CdTe provides several benefits that enhance the materials operational characteristics at ambient temperature. Recent movement in the industry is to produce larger volume detectors using CdZnTe without much known about the effects of larger geometry on performance. The purpose of this study is to get an idea of the relationship of detector performance to both area and thickness variations.

Validity of several approximations for the turbulent buoyant jet in a stagnant neutrally-stratified ambient  

SciTech Connect (OSTI)

A series of approximations are usually made in deriving integral model equations for the dispersion of a round turbulent buoyant jet into a stagnant neutrally-stratified ambient fluid. The magnitudes of differences in model predictions caused by making four of these approximations are calculated as a function of the initial densimetric Froude number and the initial relative density difference. The four approximations studied are (1) the Boussinesq approximation, (2) the use of a common Gaussian width for both mean axial velocity and mean temperature (or concentration) excess, (3) the neglect of fluctuation-correlation terms, and (4) the assumption of a linear relationship between excess density and excess temperature (or concentration). The four approximations are studied singly and then cumulatively as the predictions of the two models, one with and one without all approximations, are compared to seven low Froude number data cases. Results show that the Boussinesq approximation produces percentage differences in predictions which are about half of the initial relative density difference expressed in percentage. Use of a common Gaussian width for velocity and temperature produces differences from 6% to 30% depending on the entrainment assumption used. Fluctuation correlation effects rarely exceed 8%. Lastly, at Froude numbers below about 10 the correct nonlinear equation of state must often be used for heated waste jets to acheive accurate results, and the correct air equation of state may also be needed for low Froude number heated air jets, depending on the initial diameter and velocity.

Evaluation of the association between birth defects and exposure to ambient vinyl chloride  

SciTech Connect (OSTI)

Birth defects incidence for infants born to residents of Shawinigan, Canada in 1966-1979 were significantly higher than in three comparison communities. Since there has been a vinyl chloride polymerization plant in this town since 1943 from which ten cases of angiosarcoma of the liver have been identified, this study explores the possible association between exposure to vinyl chloride monomer (VCM) in ambient air and the occurrence of birth defects in the community. The excess of birth defects fluctuated seasonally in a way that corresponded to changes in VCM concentration in the environment. Mothers who gave birth to malformed children were younger on average in Shawinigan than in the comparison communities. However, there was no excess of still-births in Shawinigan. The excess in birth defects involved most organ systems, and variation in birth-defect rates among school districts could not be accounted for by estimates of VCM in the atmosphere. The occupational and residential histories of parents who gave birth to malformed infants were compared with those of parents of normal infants. The two groups did not differ in occupational exposure or closeness of residence to the vinyl chloride polymerization plant. Some descriptive data from this study raised the hypothesis of an association between VCM in the air and birth defects in the exposed community, but as a whole, within the sample size available, such an association could not be substantiated.

Air ejector augmented compressed air energy storage system  

DOE Patents [OSTI]

Energy is stored in slack demand periods by charging a plurality of underground reservoirs with air to the same peak storage pressure, during peak demand periods throttling the air from one storage reservoir into a gas turbine system at a constant inlet pressure until the air pressure in the reservoir falls to said constant inlet pressure, thereupon permitting air in a second reservoir to flow into said gas turbine system while drawing air from the first reservoir through a variable geometry air ejector and adjusting said variable geometry air ejector, said air flow being essentially at the constant inlet pressure of the gas turbine system.
