Description
Results from the Freshwater Fish Contaminant Monitoring Program in 2012 are summarized for three areas in Washington: the Spokane River, Pend Oreille River, and North Cascades National Park. The sampling goals were to: (1) characterize contaminant levels in fish, and (2) determine spatial and temporal patterns in contaminant levels in Spokane River fish.
Results from the Spokane River showed that levels of PCBs and PBDEs in fish remain elevated compared to most areas in Washington. Differences among sites were found for about half of the 21 site-species pairings examined. In most cases, contaminant levels have not changed from 2005.
Levels of contaminants in fish from the Pend Oreille River and the North Cascades National Park were typical of levels seen across Washington.
