- This study was conducted because the multiagency program called the Valleywide Fish Tissue Screening Study found relatively high concentrations of PCBs and chlordane in fish from Nickajack Reservoir. Fish to be analyzed for this program are collected from Tennessee River reservoirs once every three years as long as concentrations of contaminants remain low. A more indepth study is undertaken if concentrations are sufficiently high to pose a potential threat to human health or the environment. Results from the initial year (1987) of the Valleywide Fish Tissue Screening Study found sufficiently high concentrations of both PCBs and chlordane in catfish (the indicator species) from Nickajack Reservoir to warrant attention. Concentrations of these chlorinated organics exceeded the predetermined Tier 3 levels established to trigger a more indepth study to better define apparent problems. The five-catfish fillet composite sample from the lower reservoir location (Tennessee River mile 425) contained 1.9 μg/g total PCBs and 0.21 μg/g chlordane, while the composite sample from the upper area (TRM 457) contained 1.3 μg/g PCBs and 0.25 μg/g chlordane. 4 refs., 7 tabs.
