High levels of pollutants found in the deepest parts of the ocean

FIS –

“Extraordinary” high levels of toxic pollution have been discovered in the most remote and inaccessible place on the planet – the 10km deep Mariana trench in the Pacific Ocean.

By using a robotic submarine, scientist could capture small crustaceans that live in the pitch-black waters of the trench, which were contaminated with 50 times more toxic chemicals than crabs that survive in heavily polluted rivers in China.

“Pollutants were there in every single sample, regardless of depth, regardless of species,” lead author Alan Jamieson, of Newcastle University in the UK, said.

The team of researchers verified that tiny crustaceans, such as yellowish Hirondellea gigas living in darkness about 10,000 meters down in the Pacific Ocean, were found to be polluted by PCBs, used in electric transformers or paints, and PBDE chemicals used as flame retardants, Reuters reported.
