Polar bear (Ursus maritimus), adult and cub.
Spitsbergen, Svalbard, Norway.

The polar bear rates as one of the wildlife species most threatened by chemicals. As the apex of the Arctic food web, polar bears collect the highest doses of many chemicals. They also undergo periods of fasting or starving during ice melts and breeding, which may mobilize the toxic chemicals they retain.
