Bioaccumulation of hexachlorobenzene, hexachlorobutadiene and dioxins/furans downstream of organic chemical production facilities
- Environmental Protection Agency, Dallas, TX (United States)
A review of available fish tissue and bottom sediment data was conducted for waters downstream of five high volume producers of perchloroethylene, trichloroethylene and carbon tetrachloride to assess potential for bioaccumulation of` hexachlorobenzene (HCB), hexachlorobutadiene (HCBD) and polychlorinated dioxins and furans. Three facilities are located in Louisiana and two are in Texas. These compounds originate as by-products and tend to be present at extremely low or nondetected concentrations in facility discharges. However, because they are hydrophobic, persistent, and strongly bind to sediment particles, contamination of bottom sediments may occur downstream of production facilities. Exposure to contaminated sediments can result in bioaccumulation of the contaminants in aquatic biota to levels which may constitute unacceptable risks to human health and the environment.
