      Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to organohalogen compounds (OHCs) in Arctic biota, there has been a considerable number of new Arctic ...

    • Diet and metabolic state are the main factors determining concentrations of perfluoroalkyl substances in female polar bears from Svalbard 

      Tartu, Sabrina; Bourgeon, Sophie; Aars, Jon; Andersen, Magnus; Lone, Karen; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Welker, Jeffrey Martin; Routti, Heli Anna Irmeli (Journal article; Peer reviewed, 2017)
      Perfluoroalkyl substances (PFASs) have been detected in organisms worldwide, including Polar Regions. The polar bear (Ursus maritimus), the top predator of Arctic marine ecosystems, accumulates high concentrations of PFASs, ...

    • Exposure to oxychlordane is associated with shorter telomeres in arctic breeding kittiwakes 

      Blévin, Pierre; Angelier, Frédéric; Tartu, Sabrina; Ruault, Stéphanie; Bustamante, Paco; Herzke, Dorte; Moe, Børge; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2016)
      Telomeres are DNA-protein complexes located at the end of chromosomes, which play an important role in maintaining the genomic integrity. Telomeres shorten at each cell division and previous studies have shown that telomere ...

    • Mercury exposure, stress and prolactin secretion in an Arctic seabird: an experimental study 

      Tartu, Sabrina; Bustamante, Paco; Angelier, Frédéric; Lendvai, Adam Z.; Moe, Børge; Blévin, Pierre; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Peer reviewed; Journal article, 2016)
      Life-history theory predicts that long-lived organisms should reduce parental effort under inclement environmental conditions in order to favour long-term survival. Seabirds are long-lived top predators often exposed to ...

    • Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears 

      Tartu, Sabrina; Lille-Langøy, Roger; Størseth, Trond Røvik; Bourgeon, Sophie; Brunsvik, Anders; Goksøyr, Anders; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Routti, Heli (Journal article; Peer reviewed, 2017)
      There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ...
