mercury Pollution is made up of the deepest depression in the world.
the bottom of the Mariana trench, the deepest point in the ocean, polluted with mercury, found researchers from the University of Michigan in the United States.
the Scientists collected samples of fish and crustaceans at a depth of 7 km and 10 km in the Mariana trench near the Philippines and in the Kermadec trench in New Zealand, according to Newsweek.
it Turned out that the organisms of these animals gained significant amounts of methyl mercury — compounds, even more toxic than mercury. The neurotoxin formed by metabolism of benthic microorganisms in the release of mercury into water bodies.
Most of the mercury ends up in the oceans due human activities such as burning coal and oil or mining and production of metals. Of the mercury deposited on the earth’s surface and part enters the atmosphere and after the precipitation is in the ocean.
a Study presented at a scientific conference Goldschmidt Geochemistry showed that mercury has penetrated even to the remotest corners of the ocean. The food chain, it will be transmitted from small marine organisms to large, and then to the man.
