Microlitter in arctic marine benthic food chains and potential effects on sediment dwelling fauna
Marine litter pollution affects oceans globally and has today also made its way to the pristine arctic environment adding to local marine litter pollution sources. Marine litter pollution is recognized as a serious threat to the marine environment at all levels, from the UN to regional (EU, OSPAR, H...

Marine litter pollution affects oceans globally and has today also made its way to the pristine arctic environment adding to local marine litter pollution sources. Marine litter pollution is recognized as a serious threat to the marine environment at all levels, from the UN to regional (EU, OSPAR, HELCOM) and national authorities. The risk posed by microlitter to marine biota is related to their documented ubiquity and long residence time in marine ecosystems. Risks are also mediated by intrinsic toxicity of added chemicals and potential adsorbance of other pollutants. When released into the marine environment, a major part of microlitter likely accumulate in beach sand and marine sediments either immediately or after acquiring a biofilm.
