The chemical pollution was found in animals 6 miles below sea level.
Recent studies have revealed that crustaceans that live 10 kilometers (6 miles) below sea level are carrying high levels of harmful industrial chemicals from human-caused pollution. Though there have been many missions to the deepest parts of the oceans in the past, most of the Mariana and Kermadec trenches, where these polluted creatures were found, have never been visited by any humans, or even machines. In contrast to the expected excitement of exploring parts of the ocean’s deepest trenches that many would expect, researchers were thoroughly shocked by what they found.
Dr. Alan Jamieson from the University of Aberdeen conducted his research by collecting amphipod crustaceans from 7,227-10,250 meters (4.5-6.4 miles) deep into the ocean, with the use of traps that were set by deep-sea landers. Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were found in every sample tested, across three different species…
