Mercury (Hg) is a highly potent neurotoxin which is naturally present in the environment. A vast amount of the global Hg is stored in Arctic permafrost soils, immobilized by complexation with organic matter (OM). With an increasingly warmer climate, 37-81% of the near surface permafrost in the North...
