Description Mercury concentrations were assessed in 185 fish and 60 sediment samples collected from 18 lakes and two rivers across Washington State.

Largemouth bass (Micropterus salmoides) and smallmouth bass (Micropterus dolomieu) were chosen as the target species due to their wide distribution, predatory nature, and known tendency to bioaccumulate mercury. Mercury concentrations in fish tissue were found to vary widely among waterbodies and individual fish, but were positively correlated with fish age.

Mercury levels in fish are compared to human health consumption criterion. Mercury levels in sediment are compared to available North American Sediment Quality Values.
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.
