Climate change influence on the levels and trends of persistent organic pollutants (POPs) and chemicals of emerging Arctic concern (CEACs) in the Arctic physical environment – a review
This review examined how climate change is reshaping the movement and distribution of persistent organic pollutants and emerging contaminants across Arctic environments, including air, ice, permafrost, and water. Researchers found that melting permafrost, retreating sea ice, and changing precipitation patterns are releasing stored contaminants and altering how chemicals circulate through the Arctic. The study identifies microplastics as an emerging Arctic contamination concern that needs more research attention.

This review assesses how climate change influences the fate of persistent organic pollutants in the Arctic, finding growing evidence that warming, ice loss, and permafrost thaw are remobilizing legacy contaminants and altering their distribution in Arctic ecosystems.
The influence of global climate change on accumulation and toxicity of persistent organic pollutants and chemicals of emerging concern in Arctic food webs
This review examined how climate change affects the accumulation and toxicity of persistent organic pollutants in Arctic food webs. Researchers found that warming temperatures, melting permafrost, and shifting species ranges are changing how contaminants move through and concentrate in Arctic ecosystems. The study suggests that climate change and chemical pollution together may create compounding stress on Arctic wildlife populations.
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.
Thawing Permafrost Releases Industrial Contaminants into Arctic Communities
As permafrost thaws due to climate change, long-trapped industrial pollutants are being released into Arctic communities, threatening traditional foods and drinking water for Indigenous peoples. These contaminants, from both local and distant sources, are now entering the environment in new ways. The situation highlights how climate change can worsen pollution exposure and create new health risks for vulnerable communities.
Chemicals of Emerging Arctic Concern in north-western Spitsbergen snow: Distribution and sources
Researchers analyzed snowpack in north-western Spitsbergen, in the Arctic, for chemicals commonly found in personal care products such as fragrances, UV filters, and BPA. They detected these emerging contaminants across multiple sampling sites and seasons, suggesting long-range atmospheric transport from populated areas. The findings indicate that even remote Arctic environments are being contaminated by everyday consumer product chemicals.
State of knowledge on current exposure, fate and potential health effects of contaminants in polar bears from the circumpolar Arctic
Researchers reviewed decades of data on chemical contamination in polar bears and found that legacy pollutants like PCBs, chlordanes, and PFOS — many of which enter food chains via plastics and industrial runoff — remain the primary chemical threats, disrupting thyroid hormones, immune function, and lipid metabolism. While banned pollutant levels are slowly declining, newer fluorinated compounds (PFCAs) are rising in some populations, underscoring how industrial chemicals continue to accumulate in Arctic apex predators.
Arctic warming interrupts the Transpolar Drift and affects long-range transport of sea ice and ice-rafted matter
This study found that accelerating Arctic warming is disrupting the Transpolar Drift, reducing long-range sea ice transport and altering how ice-associated matter -- including pollutants -- is redistributed across the Arctic Ocean.
Canadian high arctic ice core records of organophosphate flame retardants and plasticizers
Researchers detected 19 organophosphate ester flame retardants and plasticizers in ice cores from remote Canadian high Arctic icefields, constructing a multi-decadal record from the 1970s to 2016 that documents long-range atmospheric transport of these chemicals to pristine polar regions.
Cryosphere as a temporal sink and source of microplastics in the Arctic region
This review examined the Arctic cryosphere as both a sink and source of microplastics, showing that sea ice, snow, and permafrost store significant quantities of microplastics that are increasingly released into the environment as climate warming accelerates.
Global warming releases microplastic legacy frozen in Arctic Sea ice
Researchers demonstrated that Arctic sea ice stores a legacy microplastic burden accumulated over decades, and that accelerating sea ice melt from global warming will increasingly release these stored plastics back into the ocean.
Combined threats of climate change and contaminant exposure through the lens of bioenergetics
Researchers reviewed how chemical contaminant exposure combines with climate change to affect animal energy budgets, with a focus on Arctic wildlife exposed to pollutants like persistent organic chemicals and microplastics. They found that both stressors independently increase the energy organisms need to survive, and when combined, the effects can be additive or even multiplicative. The study suggests that animals already stressed by warming temperatures may be especially vulnerable to the additional burden of environmental contaminants.
Plastics as a carrier of chemical additives to the Arctic: possibilities for strategic monitoring across the circumpolar North
Researchers reviewed evidence of plastic chemical additive transport to the Arctic via plastic pollution, identifying monitoring gaps and recommending strategic surveillance frameworks to track additive fate and accumulation across circumpolar environments and food webs.
Organic chemicals of Arctic concern in Russian coastal seas
This review synthesized monitoring data on persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in Russian Arctic coastal seas. The authors found that legacy POPs remain detectable throughout the region and that their bioaccumulation in food webs continues to pose risks to Arctic wildlife and Indigenous communities.
Transport of persistent organic pollutants: Another effect of microplastic pollution?
This review examines how microplastics act as vectors for persistent organic pollutants (POPs) in aquatic environments, covering the physical and chemical factors governing pollutant adsorption and desorption. The authors discuss how interactions between microplastics and POPs vary with polymer type, particle properties, and environmental conditions, and when these interactions may result in toxic effects on aquatic organisms.
Accumulation of Plastic Debris and Associated Contaminants in Aquatic Food Webs
Researchers built a food web model simulating microplastic and chemical contaminant transfer through an Arctic marine food chain from zooplankton to polar bears. The model found that while microplastics themselves do not biomagnify substantially through trophic levels, they can alter the bioaccumulation patterns of hydrophobic organic chemicals depending on the chemical properties and organism physiology.
Emerging pollutants of water supplies and the effect of climate change
This review examined emerging contaminants in water supplies including pharmaceuticals, pesticides, and heavy metals, with a focus on how climate change alters their mobilization, persistence, and treatment removal efficiency. The authors highlighted that current water treatment systems were not designed to handle many of these pollutants.
Climate change and the water quality threats posed by the emerging contaminants per- and polyfluoroalkyl substances (PFAS) and microplastics
This review examined how climate change amplifies the risks posed by PFAS and microplastics in freshwater and marine environments, including enhanced mobilization, altered transport, and increased human exposure pathways. The authors found that both contaminant classes are released at higher rates under warming scenarios and that microplastic breakdown generates greenhouse gases that further accelerate climate change.
Addressing the importance of microplastic particles as vectors for long-range transport of chemical contaminants: perspective in relation to prioritizing research and regulatory actions
This perspective examined the role of microplastic particles as vectors for long-range environmental transport of persistent organic pollutants (POPs), concluding that while microplastics can adsorb and carry chemical contaminants, their relative contribution to POP transport compared to other pathways requires further investigation before regulatory prioritization.
Arctic sea ice is an important temporal sink and means of transport for microplastic
This study showed that Arctic sea ice acts as a significant temporary reservoir for microplastics, trapping particles that are then released when ice melts, making sea ice both a sink and a transport mechanism for microplastic pollution.
