Abstract |
The report contains the results of an investigation by the U.S. Environmentsl Protection Agency to determine the extent of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) contamination in the environment. The report presents the findings and conclusions from four of the seven tiers (Tiers 3,5,6, and 7). These four tiers are: Tier 3 sites where 2,4,5-trichlorophenol (2,4,5-TCP) or its derivatives were formulated, blended, and packaged. Tier 5 sites where suspected contaminated pesticides were commercially applied; Tier 6 sites where certain other chemical processes could inadvertently form 2,3,7,8-TCDD; and Tier 7 background soil and fish sites. More than 4,000 samples from 862 sites nation-wide were collected and analyzed for this investigation. Sampled media included soil, sediment, fish, and various animal and plant tissues. The report also presents discussions of the environmental fate processes and health assessments related to 2,3,7,8-TCDD exposure. Finally, the report describes the quality assurance program implemented to meet the objectives of the study. |
