ClearPlastic pollution in the Arctic
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.
The problem of Microplastic Accumulation in the Arctic Ocean
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.
Investigating the sources, transfer, and fate of microplastics in the Arctic marine environment
This review synthesizes current knowledge on microplastic sources, transport pathways, and fate in Arctic marine environments, examining how MPs present in sea ice, water columns, and marine biota reflect both local and long-range transport from lower latitudes.
Estimation of plastic waste accumulation in the Arctic
Researchers analyzed sources, spatial distribution patterns, and mass transfer dynamics of plastic and microplastic pollution in the Arctic, proposing plastic waste management approaches and a community-based monitoring program to track microplastic accumulation across Arctic regions.
Microplastics in Arctic polar waters: the first reported values of particles in surface and sub-surface samples
Researchers reported some of the first measured values for microplastic particles in Arctic polar waters, finding contamination even in these remote high-latitude waters and raising questions about long-range transport mechanisms.
Microplastic pellets in Arctic marine sediments: a common source or a common process?
Researchers examined microplastic pellet contamination in Arctic marine sediments to understand whether their presence reflects common sources or shared degradation processes. The study found that microplastics are accumulating on the Arctic seafloor, contributing to growing evidence that plastic pollution reaches even the most remote ocean environments.
The Microplastics Occurrence and Toxic Effects in Marine Environment
This review examines the occurrence routes and toxic effects of microplastics in marine environments, documenting contamination even in previously pristine areas such as Arctic and Antarctic oceans and highlighting the broad ecological impacts on marine ecosystems.
Microplastic pollution in the Arctic Ocean: Assessing ingestion and potential health effects in Calanus and Neocalanus copepods
This review assessed the extent of microplastic ingestion by Arctic marine organisms and evaluated the potential risks to both wildlife and human consumers of Arctic seafood. The authors found evidence of microplastic ingestion across multiple species and called for more research on long-term ecological impacts in polar environments.
Microplastics in Surface Waters of the Russian Arctic Seas: Distribution, Concentration, Identification, and Eco-Risks for Fish
Microplastics were detected across surface waters of the Russian Arctic seas, with concentrations and polymer types varying by region and season. The findings document that even high-latitude Arctic waters are not spared from microplastic contamination, likely transported by ocean currents and rivers.
Abundance and distribution of microplastics in the surface sediments from the northern Bering and Chukchi Seas
This study documented the first records of microplastic contamination in surface sediments from the northern Bering and Chukchi Seas, including waters near Arctic Alaska, finding widespread but variable particle abundances. The findings confirm that even high-latitude Arctic seafloor sediments receive microplastic input, likely transported by ocean currents from distant sources.
Horizontal distribution of surface microplastic concentrations and water-column microplastic inventories in the Chukchi Sea, western Arctic Ocean
Researchers mapped the horizontal distribution of microplastics in the Chukchi Sea of the western Arctic Ocean, providing the first water-column microplastic inventory for this region and revealing significant contamination even in remote polar waters experiencing rapid sea-ice loss.
Microplastics Distribution within Western Arctic Seawater and Sea Ice
Researchers investigated microplastic distribution in seawater and sea ice of the western Canadian Arctic, including the previously unstudied Canadian Arctic Archipelago and Tallurutiup Imanga National Marine Conservation Area. The study found microplastic contamination throughout the region while highlighting gaps in existing Arctic microplastic data.
Plastic pollution in the marine environment
This review provides a comprehensive overview of plastic pollution in coastal and marine environments, covering everything from how plastics enter the ocean to their effects on marine life. Researchers compiled global data showing microplastic concentrations ranging widely across different water bodies and sediments, with marine organisms accumulating significant amounts. The study underscores that plastic pollution causes ecological damage through entanglement, ingestion toxicity, and the transport of invasive species.
Plastic Pollution in Oceans: a Review
This review examines plastic pollution in the world's oceans, covering sources, distribution pathways, ecological impacts, and the current state of scientific understanding of marine plastic contamination.
Marine Microplastics in Polar Region—a Spitsbergen Case Study
Researchers detected both primary and secondary microplastics in waters around Svalbard (Spitsbergen) in the Arctic during a 2017 expedition. The findings confirm that microplastic pollution has reached even remote polar regions, raising concerns about contamination of Arctic ecosystems.
Investigation of microplastic pollution in Arctic fjord water: a case study of Rijpfjorden, Northern Svalbard
Researchers investigated microplastic contamination in the remote Rijpfjorden fjord in Northern Svalbard, sampling both surface water and the water column down to 200 m, and found widespread microplastic presence even in this Arctic environment far from major pollution sources.
Remote, but Not Isolated—Microplastics in the Sub-surface Waters of the Canadian Arctic Archipelago
Microplastics were found in subsurface waters throughout the remote Canadian Arctic Archipelago, indicating that plastic pollution has reached even the most isolated polar regions. Increasing Arctic shipping routes may be introducing additional local sources of plastic contamination to these pristine environments.
