Oceans and Soil Suffer from Atmospheric Mercury Reactor

РтутьAnthropogenic mercury from burning fuel evaporates to the atmosphere and precipitates back on Earth with showers, polluting soil and water. A research led by Dr. Seth Lydon of University of Washington Bothell revealed that previous to precipitation, poisonous metal circles the globe several times. Mercury showers can take place in thousands of miles away from the pollution source.

To track the mercury sources in troposphere and stratosphere, climatologists installed a mercury detector device on an airplane and performed numerous recordings at altitudes of 19 to 23 thousand feet.

"The upper atmosphere is acting as a chemical reactor to make the mercury more able to be deposited in ecosystems," said Dr Lyman. Thus, dangerous methyl mercury might also be consumed by humans with food and drinks, since it merges with biosphere.
