Description Mercury levels were assessed in 60 fish for the first year of long-term monitoring of mercury in fish tissues across Washington State. Previous Department of Ecology studies identified elevated mercury levels which led to fish consumption advisories.

This 2005 study found mercury levels to be within typical ranges (0 - 300 ppb) of previous fish tissue studies conducted within the state. Less than 10% of samples were above the EPA recommended criterion for mercury (300 ppb), and no samples were above the National Toxics Rule criterion for mercury (825 ppb).
