Arctic permafrost may now be dangerous to everyone. Josh West, a professor of Earth Sciences and Environmental Studies and co-author of the study, led a team of experts that recovered soil above the permafrost three meters below the Yukon River's surface.
In 2012, scientists from the University of Southern California succeeded in identifying high lethal doses of dangerous mercury; still, toxic chemicals threatening the safety of everyone are stored in the Arctic permafrost. Scholars have warned the world of an impressive ‘giant mercury bomb’ that may soon explode.

When they used the discovered soil with satellite data, they found that there are substantial releases of mercury when riverbanks are eroding. The environmental mercury emissions from melting permafrost are not toxic to the people at the moment leading to immediate impacts but its effects are going to be continually becoming worse as the metal accumulates in the food chain specifically through people’s customary diets of fish and game.
Quite a lot of this mercury is being redeposited by the rivers. The ability to comprehend the erosion and reburial cycles is critical to defining the scope of the mercury menace. People in these areas could suffer the consequence of exposure for decades; further, with the increasing rates of mercury discharge; the environment too is likely to take a hard blow. Plants absorb the mercury and after they die, decompose and commingle with the
