"Permafrost soil contains more mercury than all the other soil on the planet, plus all the oceans, plus the atmosphere. So there's an enormous amount of mercury sitting in these frozen areas that, as they thaw, are causing imminent risks to health and the environment."
"The new study found that the minimum mercury release is actually twice as high, spanning from around 86 kilograms per square kilometer to as much as 131, which confirms the worst estimates of mercury release in thawing permafrost."
