Plastic pollution is omnipresent in the marine environment, including much of the Arctic. Northern fulmars (Fulmarus glacialis) are particularly vulnerable to ingesting plastics floating on the water's surface, and are an international biomonitor of this contaminant. We sampled plastic ≥1 mm in size from the stomachs of fulmars collected by Inuit hunters in Arctic Canada, as well as beached fulmars from Sable Island, Nova Scotia. The frequency of occurrence (FO) of plastic in Arctic fulmars was 62 % (100 % in Nova Scotia), and mean mass of ingested plastic was 0.027 g, with just two birds from the Arctic (3.4 %) exceeding 0.1 g while all the birds from Sable Island (n = 3) exceeded 0.1 g. This FO was lower than data from previous collections in the Arctic and North Atlantic. Additional monitoring is required to determine whether this reduced FO represents a single year anomaly, or the start of a declining trend.

Ultraviolet (UV) absorbents and industrial antioxidants are two groups of plastic-derived contaminants of emerging environmental concern. However, their distribution and fate are poorly understood in Arctic wildlife. In the present study, 16 UV absorbents (10 benzotriazole UV stabilizers (BZT-UVs) and 6 organic UV filters (UVFs)) and 7 industrial antioxidants (6 aromatic secondary amines (Ar-SAs) and 2,6-di-tert-butylphenol (26DTBP)) were analyzed in the livers of thick-billed murre (Uria lomvia; n = 28), northern fulmar (Fulmarus glacialis; n = 4), black guillemot (Cepphus grylle; n = 11), polar bear (Ursus maritimus; n = 18), beluga whale (Delphinapterus leucas; n = 10), landlocked (n = 25) and sea-run (n = 10) Arctic char (Salvelinus alpinus) from the Canadian Arctic collected between 2017 and 2021.

Seabirds ingest contaminants linked to their prey's tissues, but also adsorbed to ingested plastic debris. To explore relationships between ingested plastics and trace elements concentrations, we analyzed 25 essential non-essential trace elements in liver tissue in relation to plastic content in the gastrointestinal tract in adults of four species of Arctic seabirds with different propensity to ingest plastic. Linear Discriminant Analysis (LDA) provided a clear separation between species based on element concentrations, but not among individuals with and without plastics.

Plastic pollution threatens many organisms around the world. In particular, the northern fulmar, Fulmarus glacialis, is known to ingest high quantities of plastics. Since data are sparse in the Eurasian Arctic, we investigated plastic burdens in the stomachs of fulmar fledglings from Kongsfjorden, Svalbard.
