14th February 2017: Pollutants get everywhere

A recent study published in nature has identified highly toxic man-made chemicals present in organisms in the most remote place on the planet, 10kms deep in the Marina Trench in the Pacific Ocean. Polychlorinated biphenyls (PCBs) and polybrominated diphenyl esters (PBDEs) were produced from 1930s to 1970s were the two persistent organic pollutants (POPs) that were investigated in the study. POPs are highly harmful to lifeforms, they accumulate in tissue and do not readily breakdown. PCBs and PBDEs were found in crustaceans in the Marina Trench at levels 50x more concentrated than found in crabs surviving in heavily polluted rivers in China.
