State of knowledge on current exposure, fate and potential health effects of contaminants in polar bears from the circumpolar Arctic
The polar bear (Ursus maritimus) is among the Arctic species exposed to the highest concentrations of long-range transported bioaccumulative contaminants, such as halogenated organic compounds and mercury. Contaminant exposure is considered to be one of the largest threats to polar bears after the l...
