Hydrosphere pollution with plastic waste - from human for humans

Yavor Chenkov

Abstract

In this survey we considered the problem of pollution of the oceans with plastic waste, which is almost everywhere. Nowadays there are no specific data on the type and weight of floating plastics, especially in some remote oceanic regions of the Southern Hemisphere. According to some studies using different oceanographic models of floating debris, scientists detected more than 5 trillion macro plastic pieces with a total weight of over 268,000 tons. Data for micro plastic particles are variable due to the complexity circle they participate in. Some of them are postponed in coastal areas, another part is absorbed by marine creatures through biological cycle of substances, and sometimes one of these species are becoming a delicacy at our table... therefore the problem of plastic in the seas and oceans acquire health aspect, which requires interdisciplinary collaboration involving various specialists (marine biologists, oceanographers, healthcare workers, chemists, environmentalists NGOs, etc.)

Various studies and expeditions of many NGOs worldwide, (including the Black Sea) indicate that reaching the tourist season the influx of tourists increase the amount of plastic waste ,discharged into the sea. In temperate latitudes, (because of presence of 4 seasons) it is important for environmental organizations to plan their cleaning campaigns timely. But this is insufficient policy against ever-increasing amounts of plastic waste. Nowadays the scientists are developing various biodegradable materials that replace plastic, but even that is not enough. Recently, Japanese scientists discovered bacteria able to absorb and degrade polyethylene terephthalate (PET).This sheds new light on the ways to deal with plastic pollution of the oceans and seas.
