Toxic Contaminants in the Chesapeake Bay and its Watershed: Extent and Severity of Occurrence and Potential Biological Effects
PCBs are a group of synthetic organochlorine chemicals widely used as dielectric and coolant fluids in transformers and capacitors. In 1977, the U.S. banned the production of PCBs out of concern for their persistence in the environment as well as evidence indicating that PCBs were bioaccumulative and has the potential to cause toxic impacts. Though PCBs are no longer produced, there are continu...
متن کاملPOTENTIAL FOR HUMAN EXPOSURE TO TOXAPHENE THROUGH CONSUMPTION OF GREAT LAKES FISH Prepared for the Great Lakes Consortium by the Wisconsin Department of Health Services
Concerns have been raised about the presence of the bioaccumulating pesticide toxaphene in the tissues of Great Lakes fish. Toxaphene, banned in the U.S. since 1990, is an environmentally persistent chlorinated hydrocarbon mixture of over 670 chemical congeners. Current fish consumption advisories issued in the Great Lakes states focus on concentrations of PCBs and mercury in fish. The Great La...
متن کاملValuing a change in a fishing site without collecting characteristics data on all fishing sites: a complete but minimal model
Resource economists are often asked to value a proposed change at one, and only one, recreational site; the model we develop and estimate is applicable for those cases. The application is valuing the elimination of fish-consumption advisories on a large bay on Lake Michigan. The model is a minimal but complete: complete in that the choice set is not restricted, minimal in that only two conditio...
متن کاملPolychlorinated Biphenyls (PCBs) Update: Impact on Fish Adviso
PCBs are a group of synthetic organic chemicals that contain 209 possible individual chlorinated biphenyl compounds. These chemically related compounds are called congeners and vary in their physical and chemical properties and toxicity. There are no known natural sources of PCBs. Although banned in the United States from further production in 1979, PCBs are distributed widely in the environmen...
متن کاملAre Fish Consumption Advisories for the Great Lakes Adequately Protective against Chemical Mixtures?
BACKGROUND The North American Great Lakes are home to > 140 types of fish and are famous for recreational and commercial fishing. However, the presence of toxic substances has resulted in the issuance of fish consumption advisories that are typically based on the most restrictive contaminant. OBJECTIVES We investigated whether these advisories, which typically neglect the existence of a mixtu...
