Trophic relationships in an Arctic food web and implications for trace metal transfer

Arctic mammals that were harvested for subsistence were analyzed for Ag, Cd, and THg. Stable carbon and nitrogen isotopes were evaluated to establish trophic interactions within the Arctic food web. Food web magnification factors (FWMFs) and biomagnification factors for selected predator–prey scenarios (BMFs) were calculated to describe pathways of heavy metals in the Alaskan Arctic. Species included: Arctic fox, Polar bear, Bowhead whale, Beluga whale, Gray whale, Ringed seal, Bearded seal, Spotted seal, Ribbon seal
