"How Brain-Damaging Mercury Puts Arctic Kids at Risk"

"In the frozen far north, in Arctic Quebec, the Inuit have relied on the same nutritious foods culled from the oceans for centuries: beluga whale, fish, seal, and walrus. But some of these traditional foods have become so contaminated with brain-damaging mercury that the IQs of schoolchildren in remote Arctic villages are abnormally low.

Inuit kids with the highest exposures to mercury in the womb are four times more likely than less-exposed Inuit kids to have low IQs and require remedial education, according to new findings by a team of researchers in Canada and the United States. The children scored on average almost five points lower on IQ tests."
