ClearFirst evidence of microplastic occurrence in the marine and freshwater environments in a remote polar region of the Kola Peninsula and a correlation with human presence
Researchers documented the first evidence of microplastic contamination — both fibers and fragments — in the marine waters of the Barents Sea and remote freshwater lakes of the Kola Peninsula, with levels correlating to the degree of local human activity.
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.
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.
Study of microplastic pollution in the seas of the Russian Arctic and the Far East
This study investigated microplastic pollution in seas of the Russian Arctic and Far East, regions that have received less scientific attention. Despite their remoteness, microplastics were detected, raising concern about contamination of pristine polar 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.
Unveiling microplastics pollution in Alaskan waters and snow
Microplastic occurrence was investigated in water bodies and snow samples from Alaska, a region where the extent and distribution of microplastics in terrestrial freshwater and drinking water sources had been unknown. The study provides baseline data on microplastic contamination in this Arctic and sub-Arctic region.
The occurrence and sources of microplastics to Arctic and sub-Arctic beaches: human influence on local microplastic hotspots
Researchers characterized microplastic occurrence and sources at Arctic and sub-Arctic beaches, finding that proximity to human settlements creates local hotspots, while more remote beaches receive microplastics primarily through long-range oceanic transport.
Occurrence and sources of microplastics on Arctic beaches: Svalbard
Researchers sampled four beach sites near Longyearbyen, Svalbard, to assess microplastic contamination in the Arctic. They found microplastics at all sites, with higher concentrations closer to human settlements and wastewater discharge points. The study suggests that even remote Arctic beaches are receiving microplastic pollution, primarily from local sources rather than long-range ocean transport.
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.
Microplastic Pollution in the Surface Waters from Plain and Mountainous Lakes in Siberia, Russia
Researchers conducted the first analysis of microplastic pollution in six lakes across southern Siberia, including both mountainous and plain environments. Microplastics were detected in all lakes studied, even those in protected areas with no permanent population nearby. The findings indicate that microplastic contamination has reached remote freshwater environments in Siberia, highlighting the widespread nature of this pollution.
Presence of nanoplastics in rural and remote surface waters
Researchers detected nanoplastics in surface waters at two contrasting sites—remote Siberian Arctic tundra and Swedish forests—confirming that nanoplastic contamination extends to rural and remote freshwater environments far from urban pollution sources.
Occurrence and Distribution of Microplastics in Soils and Intertidal Sediments at Fildes Bay, Maritime Antarctica
Researchers found microplastic contamination in soils and intertidal sediments at Fildes Bay in Maritime Antarctica, with higher concentrations near research stations, demonstrating that even remote polar environments are affected by microplastic pollution.
Microplastics quantification in surface waters of the Barents, Kara and White Seas
This study measured microplastic concentrations in the surface waters of the White, Barents, and Kara Seas in the Arctic, finding particularly high levels off the coast of Novaya Zemlya. The detection of microplastics in these remote Arctic waters confirms that ocean currents carry plastic pollution to polar regions far from the original sources.
Microplastic contamination of marine environment of the Barents and Kara seas in 2019
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.
Microplastic pollution in the surface sediment of Kongsfjorden, Svalbard, Arctic
Researchers investigated microplastic pollution in surface sediments of Kongsfjorden, Svalbard, documenting MP presence in this remote Arctic fjord and contributing to understanding of microplastic distribution in polar sediment compartments.
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.
Spatiotemporal trends in microplastic pollution of surface waters of the Eurasian Arctic
Researchers conducted the most extensive survey to date of floating microplastics in the Eurasian Arctic Ocean, collecting 200 surface water samples across four Arctic seas over four years using standardized methods. The study provides a crucial baseline for tracking whether microplastic contamination in this remote and climate-sensitive ocean region is increasing over time, which matters because Arctic ecosystems are already under severe stress and microplastics can further harm the marine food web from plankton to Arctic wildlife.
Characteristics and quantification of small microplastics (<100 µm) in seasonal svalbard snow on glaciers and lands
Researchers found tiny microplastic particles (smaller than 100 micrometers) in snow samples from Arctic glaciers and tundra in Svalbard, Norway. The amounts were lower on remote glaciers and higher near the research settlement, showing that these particles travel long distances through the air but also come from nearby human activity. This highlights how microplastic pollution reaches even the most isolated places on Earth.
Microplastics in polar regions: An early warning to the world's pristine ecosystem
This review summarized evidence for microplastic contamination in Arctic and Antarctic environments — including water, sea ice, sediment, and biota — characterizing polar regions as sinks for globally transported plastic particles and calling for improved monitoring to track long-term trends.
