Inuit women in northern Quebec have five to 10 times more PCBs and insecticides in their bodies than the Quebec average, according to a study by researchers at Laval University.

The deadly chemicals come from marine mammals, which are an important part of the Inuit diet. The researchers are currently studying the effects of the contamination on newly born babies before making any recommendations for diet changes. A short report about the study appeared in La Presse on March 21.
