Record levels of mercury released by thawing permafrost in Canadian Arctic

Permafrost thaw slumps in the western Canadian Arctic are releasing record amounts of mercury into waterways, according to new research by University of Alberta ecologists.

“We measured total mercury concentrations of up to 1,200 nanograms per litre,” said PhD student Kyra St. Pierre, a Vanier Scholar who co-led the study with fellow graduate students Scott Zolkos and Sarah Shakil.
