Trend and source identification of mercury contamination in Mid-Columbia Basin Pacific lamprey larvae
The Issue: Mercury contamination and toxicity threaten Pacific lamprey recovery in the Columbia River basin. Methylmercury concentrations in larval Pacific lamprey from tributaries in the mid-Columbia were measured to be as high as 4.0 µg/g wet weight. At these concentration levels, injury is predicted to occur in more than 50% of larval and adult fish and more than 90% of early-life stage fish...
