Plant operations and waste disposal at the Department of Energy Oak Ridge Reservation (ORR) have resulted in increased concentrations of PCBs and mercury (Hg) in fish inhabiting streams located on the reservation. As a component of environmental restoration investigation, fish were collected from streams on the reservation, analyzed for tissue concentrations of PCBs and Hg, and fed to ranch mink 3 months prior to and during the breeding season. As reference, fish also were collected from the Clinch River (CR) above the ORR and from the ocean (O), and fed to mink following similar procedures. Five prepared diets containing either 75% O, 75% CR, 25% ORR + 50% O, 50% ORR + 25% O, or 75% ORR fish and 25% standard mink diet were fed to 8 female and 2 male mink, each, following normal mink farm practices. PCB (Aroclor 1260 and CB congeners) and Hg concentrations were greatest in fish collected from the ORR and diets containing ORR fish exhibited a progressive increase in PCBs and Hg concentration with increased percentage of ORR fish. Female mink fed diets containing 75% ORR fish had decreased litter size and decreased mean whole body weights, Mean weight of male offspring of females fed 75% ORR fish also were decreased. Do to the contaminated environment, other aquatic prey of mink probably have elevated contaminant burdens that would contribute to effects in mink. Adverse reproductive and health effects in mink living on the ORR are speculative at this time.
