Short Description

Composite samples of sediment, whole largescale suckers (a bottom-feeding fish), and sport fish fillets were collected from five reaches of the Spokane River between Lake Coeur d'Alene and the Columbia River (Lake Roosevelt) during July-August 1993. The samples were analyzed for polychlorinated biphenyls (PCBs) and selected metals. The objective of this screening survey was to determine if levels of these contaminants were a significant environmental concern requiring more intensive sampling or other action.

Abstract Long Description

Composite samples of sediment, whole largescale suckers (a bottom-feeding fish), and sport fish fillets were collected from five reaches of the Spokane River between Lake Coeur d'Alene and the Columbia River (Lake Roosevelt) during July-August 1993. The samples were analyzed for polychlorinated biphenyls (PCBs) and selected metals. The objective of this screening survey was to determine if levels of these contaminants were a significant environmental concern requiring more intensive sampling or other action.

Significant contamination by PCBs, zinc, lead, and cadmium was found. Follow-up sampling is recommended to identify PCB sources and evaluate potential sediment toxicity. The Washington State Department of Health is currently reviewing the data with regard to human health implications. Further analysis of the fish tissue samples is being conducted for planar PCBs, which are specific, toxic components of some PCB mixtures.
