Microlitter in arctic marine benthic food chains and potential effects on sediment dwelling fauna

By: Granberg, Maria,Winberg von Friesen, Lisa,Ask, Amalie,Collard, France

Available online: https://pub.norden.org/temanord2020-528/# This report provides both field and impact data on microlitter pollution in the arctic marine environment of Svalbard and Greenland. Microlitter concentrations and characteristics were determined in marine sediments and biota in relation to local sources. Higher concentrations and diversities were found closer to human settlements and sites where lost/dumped fishing gear accumulated. Thus, local microlitter sources were found to be present in the Arctic. The experimental studies on effects of microlitter on feeding rate, microplastic ingestion, respiration and locomotion activity in an arctic amphipod, confirmed previous studies showing effects only at very high concentrations, not yet relevant in the arctic environment. The relatively low field concentrations of microlitter found in this study should be regarded as a ‘window of opportunity’ to act to at least reduce local pollution.

Contaminants in northern fulmars (Fulmarus glacialis) exposed to plastic

By: Ask, Amalie,Anker-Nilssen, Tycho,Herzke, Dorte,Trevail, Alice,Franeker, Jan A. van,Gabrielsen, Geir Wing

Northern fulmars are seabirds which feed exclusively at sea, and as such, they are useful indicators of ocean health. Marine plastic pollution is an ever-increasing and global issue that affects the northern fulmar as they are frequently found to have ingested plastic. In this report we investigate whether the amount of ingested plastic affects the concentration of certain plastic-adsorbed toxicants in their tissues. Marine plastic pollution is a field of utmost importance. It is our hope that this continues to be an area which receives increased attention in order to elucidate the potential harmful effects plastics have on the northern fulmar and ocean health, in general.

Plastic characterization in northern fulmars (Fulmarus glacialis)

By: Ask, Amalie,Cusa, Marine,Danielsen, Jóhannis,Wing Gabrielsen, Geir

Available online: https://pub.norden.org/temanord2020-537/# Northern fulmars are pelagic seabirds known to ingest plastic, but so far most of the knowledge is on the physical characteristics of the plastic. However, plastic is a catch-all for many different types of polymers and we wanted to investigate what kinds of polymers the northern fulmars are ingesting. We did this by Fourier-transform infrared spectroscopy and found that both northern fulmars from the Faroe Islands and north-east Greenland had ingested mostly plastic made of polyethylene, followed by polypropylene and polystyrene. There were differences in the physical type of plastic ingested; fulmars from the Faroe Islands had ingested significantly more pellets compared to fulmars from NE Greenland. Thus, the physical, not polymer, composition of plastics appears to be most relevant in assessing regional differences of ingested plastic by fulmars.
