      Tulatz, Felix; Gabrielsen, Geir Wing; Bourgeon, Sophie; Herzke, Dorte; Krapp, Rupert; Langset, Magdalene; Neumann, Svenja; Lippold, Anna; Collard, France (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-22)
      Procellariiform seabirds like northern fulmars (Fulmarus glacialis) are prone to ingest and accumulate floating plastic pieces. In the North Sea region, there is a long tradition to use beached fulmars as biomonitors for marine plastic pollution. Monitoring data revealed consistently lower plastic burdens in adult fulmars compared to younger age classes. Those findings were hypothesized to partly ...
    • Occurrence of emerging brominated flame retardants and organophosphate esters in marine wildlife from the Norwegian Arctic 

      Lippold, Anna; Harju, Mikael; Aars, Jon; Blévin, Pierre; Bytingsvik, Jenny; Gabrielsen, Geir W.; Kovacs, Kit M.; Lyche, Jan Ludwig; Lydersen, Christian; Rikardsen, Audun H.; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-10)
      To understand the exposure and potential sources of emerging brominated flame retardants (EBFR) and organophosphate esters (OPEs) in marine wildlife from the Norwegian Arctic, we investigated concentrations of EBFRs in 157 tissue samples from nine species of marine vertebrates and OPEs in 34 samples from three whale species. The samples, collected from a wide range of species with contrasting ...

      Dietz, Rune; Letcher, Robert J.; Aars, Jon; Andersen, Magnus; Boltunov, Andrei; Born, Erik W.; Ciesielski, Tomasz Maciej; Das, Krishna; Dastnai, Sam; Derocher, Andrew E.; Desforges, Jean-Pierre; Eulaers, Igor; Ferguson, Steve; Hallanger, Ingeborg G.; Heide-Jørgensen, Mads P.; Heimbürger-Boavida, Lars-Eric; Hoekstra, Paul F.; Jenssen, Bjørn Munro; Kohler, Stephen Gustav; Larsen, Martin M.; Lindstrøm, Ulf Ove; Lippold, Anna; Morris, Adam; Nabe-Nielsen, Jacob; Nielsen, Nynne H.; Peacock, Elizabeth E.; Rigét, Frank F.; Rosing-Asvid, Aqqalu; Routti, Heli Anna Irmeli; Siebert, Ursula; Stenson, Garry; Stern, Gary; Strand, Jakob; Søndergaard, Jens; Treu, Gabriele; Víkingsson, Gisli A.; Wang, Feiyue; Welker, Jeffrey M.; Wilson, Simon J.; Sonne, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-16)
      There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) in Arctic biota in 2010 and 2018. Here, we provide an update on the state of the knowledge of health risk associated with Hg concentrations in Arctic marine and terrestrial mammal ...
    • Spatial variation in mercury concentrations in polar bear (Ursus maritimus) hair from the Norwegian and Russian Arctic 

      Lippold, Anna; Boltunov, Andrei; Aars, Jon; Andersen, Magnus; Blanchet, Marie-Anne; Dietz, Rune; Eulaers, Igor; Morshina, Tamara N.; Sevastyanov, Vyacheslav S.; Welker, Jeffrey M.; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)
      We examined spatial variation in total mercury (THg) concentrations in 100 hair samples collected between 2008 and 2016 from 87 polar bears (Ursus maritimus) from the Norwegian (Svalbard Archipelago, western Barents Sea) and Russian Arctic (Kara Sea, Laptev Sea, and Chukchi Sea). We used latitude and longitude of home range centroid for the Norwegian bears and capture position for the Russian bears ...
    • Temporal trends of persistent organic pollutants in Barents Sea polar bears (Ursus maritimus) in relation to changes in feeding habits and body condition 

      Lippold, Anna; Bourgeon, Sophie; Aars, Jon; Andersen, Magnus; Polder, Anuschka; Lyche, Jan Ludvig; Bytingsvik, Jenny; Jenssen, Bjørn Munro; Derocher, Andrew E.; Welker, Jeffrey Martin; Routti, Heli (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-14)
      Temporal trends of persistent organic pollutants (POPs: PCBs, OH-PCBs, <i>p,p′</i>-DDE, HCB, β-HCH, oxychlordane, BDE-47, and 153) in relation to changes in feeding habits and body condition in adult female polar bears (<i>Ursus maritimus</i>) from the Barents Sea subpopulation were examined over 20 years (1997–2017). All 306 samples were collected in the spring (April). Both stable isotope values ...
    • Temporal trends of persistent organic pollutants in Svalbard polar bears (Ursus maritimus) in relation to climate-associated changes in feeding habits 

      Lippold, Anna (Master thesis; Mastergradsoppgave, 2018-05-15)
      Persistent organic pollutants (POPs) reach the Arctic ecosystems from lower latitudes mostly via air and ocean currents. They biomagnify through Arctic food webs and reach considerably high concentrations in top predators such as polar bears (Ursus maritimus). Although many of these compounds have been banned or restricted for decades, concentrations of polychlorinated byphenyls (PCBs), organochlorine ...
