【 摘 要 】

The three major components of the research included: (a) a biotechnology based screening system to identify potential hormone mimics and antagonists (b) an animal screening system to identify biomarkers of endocrine effects and (c) a literature review to identify compounds at various DOE sites that are potential endocrine disruptors. Species of particular interest in this study were those that can serve as sentinel species (e.g., amphibians) and thus provide early warning signals for more widespread impacts on an ecosystem and its wildlife and human inhabitants. The objective of this basic research is to characterize the potential of common hydrocarbon contaminants in ecosystems to act as endocrine disruptors. Although the endocrine disrupting effects of contaminants such as dioxin and PCBs have been well characterized in both animals and humans, little is known about the capacities of other hydrocarbon contaminants to act as endocrine disruptors. Results obtained from this research project have provided information on endocrine disrupting contaminants for consideration in DOE's risk analyses for determining clean-up levels and priorities at contaminated DOE sites.
