A group of researchers at the University of Newcastle (UK) has removed from the depths of the ocean in several regions of the world sea creatures - amphipods with the aim of studying them.
As a result of examination of the digestive tracts of 90 animals, the presence of plastic was recorded in 72% of them. Moreover, as the depth increased, the amount of plastic increased.
In a depression in the New Hebrides archipelago, plastic was found in 50% of amphipods, and in the Challenger Abyss (the deepest point in the world's oceans), at a depth of 10, 800 meters, 100% of marine animals were "infected" with plastic.
The analysis showed that the plastic microparticles consisted of semi-synthetic and cellulose fibers used in the manufacture of clothing. Scientists also found nylon, polyethylene, polyamide and unknown polyvinyls, very similar to polyvinyl alcohol or polyvinyl chloride.
Researchers note with alarm that at the bottom of the world's oceans, even in the deepest places, there are less and less places free of plastic waste. Moreover, if they are partially carried out of the rivers by the current into the open sea, then they have nowhere to go from the deep ocean depressions.
According to a study published in 2017, in the period from 1950 to 2015, 8.3 billion tons of plastic were produced in the world, of which 6.3 billion tons went to waste, that is, ended up in a landfill or in the nature around us.
