Microplastics found in the stomach of deep sea creatures – study UK Nevs


Plastics were found in the stomachs of the deepest marine organisms known to exist, according to a scientific study.

Located in Roial Société Open Science paper "shows that microplastic contaminants occur in the deepest parts of the ocean".

Researchers at the University of Newcastle have discovered the presence of inserted microplastics into the hoses of beings called Lisianassoidea amphipods.

The organisms were located in six deep oceans around the Pacific coast, including Japan and Peru-Chile, at depths of 7,000 to 22,866 meters.

This is a strong indicator that oceans probably do not have areas that are not contaminated with plastic contamination in some form.

More than 72% of the tested creatures contain at least one microparticle, a study showed.

Plastic pollution has a detrimental impact on world marine organisms, and it is estimated that 322 million tonnes of plastics are produced annually.

More than five trillion plastic pieces weighing over 250,000 tons currently float on the surface of the sea.

While most of the plastics present in the oceans float on the surface, studies such as this show that degradation and fragmentation of plastics sink into deep deep sea habitats.

"Microplastics are particularly worrying in marine environments because they can be similar or smaller in size so that prey or particles selected for swallowing by marine organisms can be", the study was written.

"The size of microplasty makes them bio-available, which makes it easy to enter the food chain at different trophic levels and bioaccumulation."

The study indicated that the extent of the harmful effects of plastic pollution on marine life is not fully understood, although it is known to negatively affect about 700 species of marine species, mainly through swallowing.

Despite living in remote habitats, the research team discovered plastic and synthetic fibers, including nylon, polyethylene and polyvinyl alcohol in most of the amphipods examined.

Since many deep-sea organisms, including amphipods, have evolved to ensure nutritional success in rare cases, the likelihood of new foreign bodies being taken is high.

Microplasty that eat small types of prey can have implications for the entire food chain because amphipods are fish foods and crabs consumed by predators, including birds and humans.

"This study lists the deepest record of microplastic swallowing, indicating that anthropogenic residues are biodegradable organisms at some of the deepest locations in the oceans," researchers wrote.
