  • A quantitative kinetic clearance model for inhaled radioactive aerosols is discussed. Clearance of particles is competitive and assumed to be nonlinear. Mathematical models for calculating radiation doses to various respiratory tract tissues will be developed. The proposed model is expected to simplify calculating respiratory tract doses from bioassay data. (CBS)
  • The air monitoring program described was performed as part of an overall remediation investigation at an inactive hazardous waste disposal site located in New York State. The program was conducted to determine if significant levels of certain chemical contaminants were volatilized from the site. Laboratory analysis of ambient air samples was performed for benzene, toluene, and xylene because these chemicals were known to have been deposited at the site. The analytical results are presented. The overall remediation alternative recommended for the hazardous waste site consists of in-place containment of the waste deposits utilizing a impermeable cap with vegetative cover, soil/bentonitemore » cutoff walls and a surface water drainage system. The final remediation program includes provisions for maintenance of the facilities and monitoring to measure the program's effectiveness. 5 references, 1 table.« less
  • During excavation activities at hazardous waste sites, air monitoring is routinely conducted to ensure the safety and the proper selection of personal protective equipment (PPE) of the on-site workers. In most health and safety plans, air action levels are in place that, if exceeded, warrant an increase in worker PPE or a cessation of work until conditions are safe for worker reentry. While this is a good worker health and safety practice, it maybe insufficient to protect nearby populations. Health and safety of off-site populations can be better assured with conservative on-site air action levels, early implementation of contingency plans,more » site perimeter sampling or monitoring, off-site sampling, or a combination of these methods. This presentation will explain the rationale for this approach. Several example sites where ATSDR was involved with recommendations to protect off-site population during excavation activities using this approach will be discussed.« less
  • The Robbins Particulate Study (RPS) from October, 1995 through September, 1996 characterized PM2.5 and PM10 mass, chemical concentrations, and source contributions at four sites in neighborhoods surrounding the Robbins Waste-to-Energy (WTE) facility, southwest of Chicago, IL. The design of the measurement program and methodology of analyses are described in a previous paper. PM2.5 data were obtained from the fine-particle filter of dichotomous samplers, rather than samplers intended to provide federal reference method (FRM) sampling. No exceedances of the 24-hour-average National Ambient Air Quality Standard (NAAQS) for PM10 of 150 {micro}g/m{sup 3} were found at any of the four sites; themore » maximum concentration was 61.7 {micro}g/m{sup 3}. Annual-average PM10 concentrations were similar at the four measurement locations, ranging from 24.7 to 27.4 {micro}g/m{sup 3}. These values are approximately half of the annual-average PM10 NAAQS of 50 {micro}g/m{sup 3}. The highest PM2.5 mass concentration of 32.2 {micro}g/m{sup 3} was less than PM2.5 standard of 65 {micro}g/m{sup 3}. The annual-average PM2.5 at one site was 15.2 {micro}g/m{sup 3}, slightly exceeding the three-year annual PM2.5 standard of 15 {micro}g/m{sup 3}, but the spatial average at the four sites was less than 15 {micro}g/m{sup 3}. Annual-average PM10 source contributions determined by a Chemical Mass Balance on half of the samples were: (1) geological (20% to 23%); (2) secondary sulfate (24% to 25%); (3) secondary nitrate (17% to 20%); (4) motor vehicle exhaust (18% to 20%); (5) steel production (4% to 6%); (6) road salt (3% to 7%); (7) residential wood combustion (3% to 5%); and (8) coal combustion ({approximately} 1.5%). Large contributors to trace metal concentrations (such as copper, zinc, lead, cadmium, and zirconium) were minor contributors to PM2.5 and PM10. Sources of the trace metals were not quantified by CMB owing to lack of industry-specific source profiles.« less
  • This paper summarizes Human Health Risk Assessments of the proposed use of combined ash from the H-Power municipal waste combustor (MWC) in two beneficial uses: (1) Landfill Daily Cover for the Waimanalo Gulch Sanitary Landfill in Ewa, O`ahu, Hawaii, which is operated by Waste Management of Hawaii, Inc. for the City and County of Honolulu and (2) Landfill Final Cover, a component in the final cover of the Waipahu landfill, in Waipahu, O`ahu, Hawaii. The human health risk assessment represents one phase of a larger project involving the investigation of several potential uses of H-Power MWC ash as alternatives tomore » the current practice of disposal in a lined monofill located at the Waimanalo Gulch Sanitary Landfill. The ash consists of approximately 70% bottom ash and 30% fly ash from the MWC, hereafter referred to as H-Power combined ash. At this time, three alternative uses of H-Power combined ash have been identified: The first option consists of using H-Power combined ash as a component in the final cover in the closure of the Waipahu Landfill; the second option consists of using H-Power combined ash as daily cover at the Waimanalo Gulch Sanitary Landfill; and, the third option consists of mixing H-Power combined ash into aggregate to be used in roadway paving material.« less
