Fish sampled in four Alaskan national parks have tested positive for mercury and in some cases exceeded State of Alaska unlimited human consumption thresholds for women and children. The testing was part of a multi-year U.S. Geological Survey and National Park Service study of fish in remote, high elevation lakes and streams in 21 national parks across 10 western states and Alaska. Mercury was found in fish from Tanada Lake, Summit Lake, and Copper Lake in Wrangell-St. Elias. Please see this link for more information. kln
