Plastic pollution is a contaminant of global concern, as it present even in remote ecosystems – like the Arctic. Arctic seabirds are vulnerable to ingesting plastic pollution, and these ingested particles shed form microplastics via guano. This suggests that seabird guano may act vector for movement into around northern ecosystems. While contaminant-laden deposition patterns create clear concentration gradient chemicals colonies, this has not yet been investigated with pollution. Here we...
Plastic pollution has been reported to affect Arctic mammals and birds. There are strengths limitations monitoring litter microplastics using One strength is the direct use of these data understand potential impacts on biodiversity as well effects human health, if selected species consumed. Monitoring programs must be practically designed with all purposes in mind, a spectrum approaches will required. Spatial temporal trends plastic can built information obtained from studies northern...
The Arctic Monitoring and Assessment Programme has published a plan guidelines for the monitoring of litter microplastics (MP) in Arctic. Here, we look beyond suggestions immediate discuss challenges, opportunities, future strategies long-term MP Challenges are related to environmental conditions, lack harmonization standardization measurements, coordinated harmonized data storage. Furthermore, major knowledge gaps exist with regard benchmark levels, transport, sources, effects, which should...
Abstract Since first being introduced for public use in the 1960s, plastic has become one of most pervasive and ubiquitous forms pollution globally. The potential fate effects on birds is a rapidly growing area research, but knowledge terrestrial freshwater species limited. Birds prey have been particularly understudied, with no published data ingestion raptors Canada to date, very few studies To assess raptors, we analysed contents upper gastrointestinal tracts from total 234 individuals...

Recent studies have identified the presence of microplastics and other anthropogenic microparticles in Arctic marine environments, but very little is known about sub-Arctic freshwater systems. Given importance systems to health northern communities, their large input water Ocean, circumpolar rivers lakes should be considered within context region. Sample collections for this study were conducted July August 2021 via a collaborative community-based approach. Thirty surface samples collected...
As plastic pollution continues to persist at a global level, the Arctic has drawn increased research interest as possible sink for marine pollutants. Plastic and microplastics are highly durable can be transported across vast distances. To date, only handful of studies have directly assessed in mammals. In Canada, it is still unclear whether they show concrete propensity microplastic retention ingestion. Atlantic walruses ( Odobenus rosmarus (Linnaeus, 1758)) economically culturally...
The purpose of the guidelines is to review existing knowledge and provide guidance for designing an Arctic monitoring program that will track litter MP. topics litter, plastic pollution, MP are addressed in many fora, including several Council working groups: Monitoring Assessment Programme (AMAP; https://www.amap.no/documents/doc/amap-assessment-2016-chemicals-of-emerging-arctic-concern/1624), Protection Marine Environment (PAME, 2019), Conservation Flora Fauna (CAFF). development its...
