Every year, mankind additionally adds additional to the main volume of plastic pollution of the world's oceans, thus creating an even greater problem of plastic pollution than was previously mentioned. Today, a talented team of environmental experts from the University of Manchester has released their new study on how microplastics – which in this context pose the main threat to marine and oceanic ecosystems – can accumulate not only on the surface of the water, forming a kind of islands, but also gather in rather considerable heaps in the deep layers of the ocean, further complicating the ecological situation.
The experts took the Mediterranean Sea as the basis of the comparison model, where they compiled their map of plastic pollution – they found that microplastic tends to collect in those parts of the deep layers of water that are formed by underwater currents that, along with garbage, also carry oxygenated water and various kinds important trace elements to maintain a normal marine ecosystem.
Moreover, the researchers noted that it is the underwater heaps of microplastics that have a more pronounced threat, since they are formed unevenly and almost always randomly, which not only complicates the ability to predict the place of their subsequent appearance, but also directly eliminate from under water. Moreover, according to the researchers, most of this microplastic is made up of various fabric materials that previously served as the basis for clothing, shoes and other similar products, which are often thoughtlessly thrown away by people.
In addition, microplastic has another feature, namely the ability to accumulate in the regions most active from the point of view of the underwater ecosystem, thus posing a great threat for a much longer time. It remains only to wait for the next stage of the study, when specialists must identify the real indicators of the current microplastic pollution in the Mediterranean Sea.
