Melting Permafrost Shown to Release Mercury in Arctic Areas
DURHAM, NH — A team of researchers working north of the Arctic Circle in Abisko, Sweden, have learned that as global temperatures continue to rise, the thawing of permafrost in Arctic areas accelerates, releasing mercury that has been trapped in the frozen ground for decades or centuries. The mercury may be 'methylated' when in contact with water, and be present in surrounding waterways, soil and air.
“Our research suggests that Arctic wildlife, such as birds and fish, may be at increased risk of exposure to higher levels of methylmercury that could ultimately ...
