Huskies lend insight into mercury risk
Date:11/20/2011

ay into the ecosystem. The main sources of mercury injection into the ecosystem are coal-generated power plants.

The researchers, from the University of Alaska Fairbanks, analysed groups of 12 huskies in four villages along the Yukon River and in a reference kennel. The huskies were typical racing dogs with similar lineage, sex and age and in their peak racing years. The huskies kept in the reference kennel were fed on a balanced, commercial diet.

After two months of feeding the huskies on the subsistence diets, blood samples were taken to determine their antioxidant power whilst hair samples were taken to determine total mercury concentrations in their body.

The lead author of the study, Professor Kriya Dunlap, said: "The amounts of mercury in the salmon are well below Environmental Protection Agency limits and the health benefits compared to processed food are still quite significant; however, the fact that health indices may be impaired by mercury levels indicates that monitoring should continue and that mercury generation should be monitored."
