Mercury pollution still growing in Arctic lakes and fish: researcher

An Environment Canada scientist based out of the National Wildlife Research Centre at Carleton University in Ottawa is studying how climate change is impacting how much toxic mercury is getting into the food chain from pollution that settles in Arctic lakes.
In high enough doses, mercury poisoning can lead to damaged hearing, speech and vision, and even death.

“Mercury is a contaminant of concern because it can bio-magnify to high levels in wildlife,” said Chételat, who is leading the project with Murray Richardson from Carleton’s geography and environmental studies department.
