Arctic mammals can metabolize some pesticides, limits human exposure

6th August 2014

Fortunately, you are not always what you eat – at least in Canada's Arctic. New research from the University of Guelph reveals that arctic mammals such as caribou can metabolize some current-use pesticides (CUPs) ingested in vegetation.

This limits exposures in animals that consume the caribou – including humans.

"This is good news for the wildlife and people of the Arctic who survive by hunting caribou and other animals," said Adam Morris, a PhD student in the School of Environmental Sciences and lead author of the study published recently in Environmental Toxicology & Chemistry.

"The lack of any significant biomagnification through the food chain indicates that there is very little risk of harm from exposure to these CUPs in this region."
