Summary

There is contamination by micro plastics in the oceans, this can affect animals in the sea which is contaminated to depths of 7000 to 10890 m the most contaminated parts of the ocean are being found in the deepest of these examined several animals and 72 percent of them had at least some of this contamination of anthropogenic waste in them several studies confirmed that there is ingestion of micro plastics in the deep ocean.

They have done other studies that indicate that 322 million tons of plastic are produced per year and on the surface have been found more than 5 trillion plastic weighing more than 250,000 have only removed 4.8 and 12.7 million tons from the sea in 2010.

Pollutants

The pollutants of the ocean are man-made microfibres and fragments, including microplastics, which were found in the hindguts of amphipods from six of the deepest parts of the Earth's oceans. Plastic has been present at hadal depths for the last couple of decades.

Sources

An estimated 322 million tons of plastic are produced annually, with more than 5 trillion plastic pieces weighing over 250 000 tons currently floating on the surface.

Impacts

Over 72% of individuals examined (65 of 90) contained at least one microparticle. The number of microparticles ingested per individual across all trenches ranged from 1 to 8. The mean and standard error of microparticles varied per trench, from 0.9 ± 0.4 (New Hebrides Trench) to 3.3 ± 0.7 (Mariana Trench).

Non-Point Source Pollution

The sources in the ocean are Non-Point Sources because their origins are widely dispersed through the ocean with diverse origins.

Persistent

Ubiquitous microplastic pollution is within the deep sea, and does it extend to full ocean depth?

The majority of plastic present in the oceans can be observed floating on the surface [9]. The degradation and fragmentation of plastics will ultimately result in sinking to the underlying deep-sea habitats, where opportunities for dispersal become ever more limited

Acute

ornellacani — 2023-11-08 00:26:53 UTC

We can determine that the pollution in the oceans can be stablished as Acute because the health effects caused on sea animals are serious and notable and are caused in a short period of time.
