Hazardous waste sites, importance determination

Only qualified individuals should be allowed to develop air monitoring strategies. In addition, only trained and qualified field personnel should operate sereening equipment and be allowed to interpret results. For many sites, the results obtained from direet reading instruments ean help determine a variety of important faetors on a hazardous waste site. These faetors inelude ... [Pg.60]

Polybrominated Diphenyl Ethers. Information on the relative importance of different routes of exposure to PBDEs is limited. Data on the concentrations of PBDEs in foods, collected using a market-basket approach, are needed to determine concentrations of PBDEs in foods consumed by the general population. Data on the PBDE concentrations in foods grown in contaminated areas, particularly in the vicinity of hazardous waste sites, are also needed. Data on congener-specific PBDE analysis of food, especially plant products, would be useful. More monitoring data on the concentrations of total PBDEs as well as conquers in air in remote, rural, urban, and areas near hazardous waste sites and incinerators are needed. Data on PBDE concentrations in finished drinking water nationwide would be helpful. [Pg.381]

The determination of known organic pollutants in the environment (target analysis) and the identification of all possible organic pollutants, i.e. in hazardous waste sites (non-target analysis), are important tasks in environmental analysis. However, the chemical, photochemical and microbiological... [Pg.162]

Bioavailability from Environmental Media. Chlorobenzene is absorbed primarily following inhalation of contaminated air. There is also some potential for exposure from water and soil. Chlorobenzene has been detected at low levels in surface, ground, and drinking water, but no information was found on levels in food. Since chlorobenzene binds, tightly to soil particles, skin contact with or ingestion of contaminated soil may be an important source of exposure, particularly in children living near hazardous waste sites. Additional studies would be useful to determine if soil-bound chlorobenzene is bioavailable. [Pg.59]

Health outcome data and parameters are the third major source of data for health assessments. The identification, review, and evaluation of health outcome parameters are interactive processes involving ATSDR, data source generators, and the community involved. Health outcome data are community-specific and may include databases at the local, state, and national level, as well as data from private health care organizations and professional institutions and associations. Databases to be considered include medical records, morbidity and mortality data, tumor and disease registries, birth statistics, and surveillance data. Relevant health outcome data play an important role in assessing the public health implications associated with a hazardous waste site and in determining which follow-up health activities are needed. [Pg.1302]

Additional exposure to PCBs could occur for children who live near hazardous waste sites. Since children spend a lot of time playing on the ground, both indoors and out, they come into more contact with contaminants found on dust and dirt particles. They may be exposed to PCBs by dermal contact with PCB-contaminated soil and by ingesting contaminated soil from their unwashed hands and other hand-to-mouth behavior. The determination of PCBs in dust and dirt can therefore be important for predicting children s exposure. However, quantitative information regarding the bioavailability and amount of PCBs that children are exposed to through contact with contaminated soils are unavailable. [Pg.641]

Developmental toxicity. No human studies on developmental effects are available for exposure to RDX via inhalation, oral, or dermal routes. No inhalation or dermal studies are available for animals. Maternal deaths were observed in rats exposed to 20 mg/kg/day of RDX (Army 1980b, 1986d). The one available oral study in rabbits revealed no fetotoxicity (Army 1980b). No pharmacokinetic data are available that can be used to determine whether the developmental system is likely to be a target organ. Further developmental studies via the oral route are important to determine whether humans exposed to RDX at or near hazardous waste sites are at risk of experiencing adverse developmental effects. [Pg.58]

Other speeifie ehemieal hazards that workers may eome into eontaet with are too numerous to mention. The effeets from these ehemieals vary widely. It is important to know if there are ehemieals being brought on site for any reason, along with the ehemieals already at the site and ehemieal wastes present on site. After you have obtained a eomprehensive ehemieal library, you should determine eompatibility and synergistie, additive, and other effeets of ehemieal mixing. This might inelude fire, explosion, or release. [Pg.78]
