PFAS reaches the Arctic with air and sea currents from North America, Asia and Europe. PFAS can, among other things, cause damage to people's immune system. As polar bears and humans are at the top of the food chain in the Arctic, they can have concentrations of PFAS that are up to 30 million times higher than in plankton algae in the sea.
