The spatial and temporal trends of mercury in the Arctic have been studied through the analysis of this metal in hard tissues, i.e. teeth and hair, in ringed seals (Phoca hispida) and polar bears (Ursus maritimus). Sex had no influence on the mercury concentrations while age was a significant factor...
