The polar bear as a biological indicator of the environmental mercury burden. Arctic 35(3

ABSTRACT. 128 fresh (current) and 18 preserved (museum) polar bear hair samples were subjected to mercury analysis. Mercury levels ranging from <0.5-44.3 ppm were observed in the fresh samples with a geographic distribution showing higher levels in the western Arctic and substantially lower level...
