Arctic lakes can be polluted by bird droppings



"Pollution is swept to pristine areas of the Arctic by wind and sea. But now researchers have pinned down an important mode of transport that creates local toxic hotspots: sea birds. Canadian researchers have found that lakes in the Arctic that are frequented by northern fulmars (Fulmarus glacialis) can harbour 10-60 times more pollutants than neighbouring, birdless lakes. These pollutants include persistent, toxic compounds such as mercury, DDT and hexachlorobenzene (HCB), which were once common ingredients in pesticides and fungicides."
