Abstract Long Description

In 2002, the Department of Ecology′s Environmental Assessment Program conducted a study (Mercury in Edible Fish Tissue and Sediments from Selected Lakes and Rivers in Washington State) of mercury concentrations in freshwater fish across Washington state. The statewide effort is a followup to a 2000 study that found elevated mercury levels in fish in Lake Whatcom (in Whatcom County).

Total mercury concentrations were measured in edible muscle tissue from 185 bass, collected from 18 lakes and two rivers in 13 counties across Washington.

Large-mouth bass and small-mouth bass were chosen as the target species due to their wide distribution, predatory nature (placing them higher on the food chain) and known tendency to accumulate mercury in their muscle tissue. Sediment and water samples also were collected from each of the water bodies to evaluate other factors that may influence how mercury gets into the fish.
