What pollution can do to our oceans, a scary, scary finding –

Plastic isn’t the only human pollutant infiltrating the deepest corners of the ocean.

Two separate studies presented at the Goldschmidt geochemistry conference this week found mercury in fish and crustaceans living 11,000 meters (approximately 36,000 feet) under the sea in the Mariana Trench.

“This is a surprise,” Dr. Ruoyu Sun, a scientist from Tianjin University in China who led one of the research teams, said in a Goldschmidt Conference press release published by Phys.org.

Scientists have long known that mercury, which is poisonous to both humans and animals, enters the ocean and the animals within it, concentrating in higher amounts as it works its way up the food web through a process called bioaccumulation. Swordfish, for example, contain 40 times the amount of mercury that salmon do. This means that humans who eat lots of fish are at risk from mercury poisoning, Newsweek pointed out. This can cause neurological and heart damage, and is especially dangerous for developing fetuses.
