Description A range of potentially toxic metals and organic compounds were analyzed in sediments collected from 14 northeast Washington lakes thought to be minimally impacted by local human activities. One lake and one river were also sampled in northern Idaho. Fish tissues also were collected and will be published later in a second report (Part 2). The goal of the overall study was to provide regional-scale sediment and fish-tissue data to support contaminant studies and cleanup activities associated with northeastern Washington waterbodies. The chemicals analyzed in sediment included antimony, arsenic, barium, cadmium, chromium, copper, iron, lead, manganese, mercury, zinc, PCBs, dioxins, and brominated flame retardants. Sensitive analytical methods were used to achieve low detection limits for the target chemicals.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
