Title: Air pollution effects field research facility: 3. UV-B exposure and monitoring system

Abstract

The Oak Ridge National Laboratory Outdoor UltraViolet-B (UV-B) Exposure and Monitoring Facility was developed in 1980 to provide well-controlled and -monitored exposure of specific terrestrial plant. species to elevated levels of ultraviolet (UV) radiation. The introduction of various anthropogenic agents into the earth`s stratosphere has resulted in a decrease in the volume of ozone (O{sub 3}) present here. The decrease in O{sub 3} has resulted in an increase in the level of UV radiation reaching thee earth`s surface. Of particular interest is the level of UV-B, because it has the most detrimental effect on living tissue. A thorough understanding of the effects of elevated levels of UV-B on living tissue is critical to the formulation of economic policy regarding production of such agents and alternative strategies. The UV region of interest is referred to as UV-B and corresponds to radiation with a wavelength of 290 to 320 nm. Design, operation, and performance of the automated generation, exposure, and monitoring system are described. The system has proved to be reliable and easy to maintain and operate, and it provides significant flexibility in exposure programs. The system software is described, and detailed listings are provided. The ability to expose plants to controlledmore » set point percentages of UV-B above the ambient level was developed.« less

    The Ozone Flow Control and Monitoring System was developed in 1986 for the controlled exposure of diverse plant species to various concentrations of ozone gas. Design, operation, and performance are described for the automated system for generation, distribution, sampling, analysis, and control of ozone gas for plant exposure. The system has proved to be reliable, easy to maintain, and flexible in adapting to exposure programs. System software is reliable, and the user interface (CRT keyboard) is easy to use, providing quick-glance viewing of overall exposure conditions. The capability to expose plants to ozone concentrations in multiples of the ambient ozonemore » level has been added, and software improvements in the areas of system response and user input are planned. 19 figs., 3 tabs.« less

  • Effects of carbon dioxide (CO2) content of the air on the response of flame photometric sulfur gas analyzers of two types, the Tracor model 270 HA sulfur chromatograph and the Meloy model SA 185 total sulfur analyzer, were studied. These analyzers were used in the Regional Air Monitoring System (RAMS). For each instrument, measurements were made to determine response to a matrix of five CO2 levels and three sulfur dioxide (SO2) levels. Measurements were also made of CO2 concentrations in the influent to and effluent from heatless air dryers providing zero air for calibration at the RAMS stations.

  • A humidity-generation system was designed, constructed, and tested to increase relative humidity (RH) within open-top field chambers under field conditions. The system consisted of a gas-fired steam boiler capable of generating 450 kg of steam at 1.055 kg/sq cm pressure. A modulating valve, controlled by a humidity sensor, metered steam to the chambers. Alfalfa plants exposed to 0.20 ppm of ozone at high RH 7 hrs/day for 2 days had visible injury to more than 50% of the leaves and increased leaf crop. Chronic exposure of alfalfa to ambient ozone at elevated RH over three harvest periods, resulted in 40%more » visible injury in the first and second harvests, and increased stomatal conductance. At the third harvest, exposure to ozone with elevated RH reduced dry weight and increased defoliation.« less

  • The Energy Security Act of 1980 established a program to provide financial assistance to private industry in the construction and operation of commercial-scale synthetic-fuels plants. The Cool Water Coal Gasification Program is one of the four projects awarded financial assistance. This Program agreed to comply with existing environmental-monitoring regulations and to develop an Environmental Monitoring Plan incorporating supplemental monitoring in the areas of water, air, solid waste, worker health and safety, and socio-economic impacts during the period 1984-1989. As the first commercial-scale integrated gasification combined-cycle plant for generating energy from coal, the plant is designed to process a variety ofmore » coals with no liquid discharge, produce non-hazardous solid wastes, and produce very few air emissions. Monitoring data are to provide an information base for evaluating plant operations and for establishing information on environmental uncertainties associated with replication of synthetic-fuels facilities. Comprehensive Phase monitoring was conducted after the Commissioning Phase and start-up of plant operations was completed during February, 1985. Results include source monitoring, pollution-control performance, ambient-air monitoring, compliance monitoring, quality assurance/quality control, and problems associated with plant operations.« less

  • This document represents Volume 2 of a 5-volume quality assurance (QA) handbook series dedicated to air pollution measurement systems. Volume 2 is dedicated to the Ambient Air Quality Surveillance Program and the data collection activities of that program. The intent of the document is twofold. The first is to provide additional information and guidance on the material covered in the Code of Federal Regulations pertaining to the Ambient Air Quality Surveillance Program. The second is to establish a set of consistent QA practices that will improve the quality of the nation`s ambient air data and ensure data comparability among sitesmore » across the nation. Therefore, the document is written for technical personnel at State and local monitoring agencies and is intended to provide enough information to develop a quality for ambient air quality monitoring.« less
