Human mercury pollution found at the deepest ocean

For many decades, humans have been putting mercury into the ocean, contaminating big fish like tuna and swordfish. But we haven’t fully realized how deep human-produced mercury could move down the ocean until now – and now scientist have found mercury pollution at the deepest parts of the ocean.

Ocean to Table Mercury: a Rising Risk

For fish eaters, mercury consumption is an ever-present worry but often pushed to the backs of our minds. But the risk of mercury poisoning is only increasing as human activity introduce more mercury into the ocean and atmosphere. In their recent paper, Lavoie and his colleagues estimate how much mercury is reaching our plates through […]

What’s in the Hair of a Polar Bear?

The accumulation of toxic methylmercury is a serious threat to wildlife all over the world – especially top predators in polar regions, like polar bears. Young polar bears are often the most vulnerable to detrimental effects of pollutants. To learn more about levels of mercury in polar bear cubs and their mothers, scientists measured total […]

Top predators reveal the extent of mercury pollution in Canadian waters

Common loons, walleye, northern pike, and yellow perch play integral roles in ecosystem dynamics and environmental policy decisions. In this research project, they act as useful indicators to determine dangerously toxic levels of methylmercury in Canada. Samantha DeCuolloSamantha works as a laboratory technician in the Menden-Deuer laboratory at the Graduate School of Oceanography (GSO). She […]
