A recent survey of Arctic permafrost has revealed that the northern tundra holds the world's largest reserve of mercury, with its size estimated to be in the tens of millions of gallons. Ordinarily, the presence of the toxic metal wouldn't be a problem, as it is locked away in the frozen soil, but researchers are concerned that as the permafrost melts due to global warming, that mercury trapped there could be released into the environment.
