Studying amphipods, small crustaceans that include more than 7,000 species, in the Mariana Trench and the Kermadec Trench (both in the Pacific Ocean), the team led by Jamieson found extremely high levels of Persistent Organic Compounds (POPs). ) in the fatty tissue of crustaceans.

"We have identified extraordinary levels of POPs in endemic amphipods from two of the deepest ocean trenches on the planet," they say in the report.

“The levels of pollutants are considerably higher than the levels documented in the regions closest to mass industrialization, indicating a bioaccumulation of anthropogenic pollution”, the study continues which concludes assuming that “these pollutants are present in the oceans of all the world and fill the ocean depths ”.

Now scientists are preparing to analyze the consequences that this can have on the biodiversity of the area and how it can affect the oceanic ecosystem.
