Abstract

Contaminants present in coal mine tailings are transported from the mine location to the marine ecosystem by fresh water runoff. Organisms take up these contaminants via water and sediment. As contaminants move through the food web, they become more concentrated at higher trophic levels. Mercury (Hg) is found to accumulate in top predators of the Arctic ecosystem in levels that
can affect the functioning of organisms. Mercury in the Arctic environment also originates from global sources due to long-range transport. The main global sources of mercury emissions to air are coal fired power stations and small scale gold mining (map 1).
