Greenland ice core reveals history of pollution in the Arctic
Date:8/19/2008

esearch professor at DRI, said there is still cause for concern.

"Contamination of other sectors may be increasing because of the rapid coal-driven growth of Asian economies," they wrote in the report. They argued the consequence may be greater risk to the food chain as toxic heavy metals from industrial activities in Asian nations are transported through the atmosphere and deposited in the polar regions.

Food chain contamination through toxic metal absorption from both the environment and from consumption of contaminated food sources could make its way to humans, who feed on long-lived land and marine animals such as caribou, seals and whale.

"Impacts on human health in the Arctic region haven't been determined," said McConnell. But he suggested cleaner burning coal technologies, or better yet reduced reliance on coal burning, may head off the potential problem.
