Scientists said about the giant amounts of mercury, preserved in the permafrost

In the permafrost of the Northern hemisphere preserved a huge amount of mercury. It is reported by the American geophysical Union (AGU) citing the latest study published in the AGU journal Geophysical Research Letters.

The researchers examined core samples from the permafrost, taken from 2004 to 2012 in various locations of Alaska.

According to scientists, in the permafrost of the Northern hemisphere contains about 793 kiloton of mercury, 10 times more than was received over the last 30 years of human activity. Value is also more than twice the total mercury content in other places on the planet: the soil, the oceans and the atmosphere.

«What happens if the permafrost melts? How far will spread the mercury? This questions we have to answer,» – said the study’s lead author Paul Schuster.

Melting glaciers may release such amounts of mercury, it will affect the ecosystem of the entire planet, warned the researchers.

Scientists have noted that Alaska and other Northern regions may be in the area of methyl mercury pollution. This form of mercury is a dangerous toxin that causes neurological disease in animals.
