        Contaminants in the Arctic Food Chain

        This video segment adapted from LOKE Films and the Arctic Monitoring and Assessment Programme describes how contaminants such as mercury and PCBs affect Arctic wildlife. Learn about how pollutants accumulate in the fats of animals and how species at the top of a food chain, such as glaucous gulls and polar bears, have higher levels of toxins than species at lower trophic levels. This resource is part of the Polar Sciences collection.
