Marine Plastic Debris Pollution in the Western Sector of the Russian Arctic
AI summary Read the abstract
This Russian article reviews the accumulation of plastic waste and microplastics in the Arctic Ocean and the Barents Sea, noting that microplastics have been found not only in Arctic waters but also in sea ice, sediments, and Arctic organisms. The fragile Arctic ecosystem is particularly vulnerable to plastic pollution that arrives via ocean currents from populated regions.
The article discusses the pollution of marine environment with plastic waste, in particular, the accumulation of microplastics in the oceans, which is one of the most serious environmental problems both in the world and in the Russian Arctic. Alongside with other world oceans, the Arctic Ocean and the Barents Sea have become places of plastic accumulation, causing great harm to the fragile ecosystem of the Arctic region. Researchers have found microplastics not only in Arctic waters, but also in the ice of the Arctic seas. Plastic debris is carried by ocean currents from more densely populated areas of the planet. Local sources, such as fishing and other commercial activities, as well as waste water, are one more reason. Microplastics adversely affect living organisms in the ocean. In particular, plastic can cause physical harm and disrupt body formation of marine animals, as well as cause death by suffocation or ingestion of plastic. At the same time, plastics can accumulate persistent organic pollutants on their surface, which can poison marine animals, damaging the entire food chain.

This Russian-language study measured microplastic contamination in the Barents and Kara Seas in 2019, two Arctic ocean regions experiencing rapid environmental change. The findings document plastic pollution in these remote polar waters, which serve as important ecosystems for fish, marine mammals, and seabirds.
The problem of Microplastic Accumulation in the Arctic Ocean
AI summary Read the abstract
This review highlights the emerging threat of microplastic accumulation in the rapidly warming Arctic Ocean, documenting MP presence in seawater, sediments, sea ice, and marine organisms and identifying the Arctic as a convergence zone for plastic pollution transported by ocean currents.
Plastic pollution in the Arctic
AI summary Read the abstract
This review describes how plastic pollution, including microplastics, has spread throughout the Arctic despite its remoteness, carried by ocean currents, rivers, and wind from lower latitudes. Plastics accumulate in Arctic ice, water, soil, and wildlife, and even if all plastic production stopped today, existing plastic would continue fragmenting into microplastics for decades. The contamination of this sensitive ecosystem is concerning because Arctic food webs, including fish consumed by humans, are already affected.
