    • Is Glacial Meltwater a Secondary Source of Legacy Contaminants to Arctic Coastal Food Webs? 

      Mcgovern, Maeve; Warner, Nicholas Alexander; Borgå, Katrine; Evenset, Anita; Carlsson, Pernilla Marianne; Skogsberg, Stina Linnea Emelie; Søreide, Janne; Ruus, Anders; Christensen, Guttorm; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-26)
      Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal food webs. Here, we present concentrations of selected POPs in zooplankton (spatially and seasonally), as well as zoobenthos and sculpin (spatially) from Isfjorden, Svalbard. ...

    • Screening new PFAS compounds 2018 

      Hanssen, Linda; Herzke, Dorte; Nikiforov, Vladimir; Moe, Børge; Nygård, Torgeir; van Dijk, Jiska Joanneke; Gabrielsen, Geir W.; Fuglei, Eva; Yeung, Leo; Vogelsang, Christian; Carlsson, Pernilla Marianne (Research report; Forskningsrapport, 2019)
      This screening project has focused on the occurrence of conventional andemerging PFASs in terrestrial and marine environments, including the Arctic. Conventional PFASs were found to be wide-spread in the environment and for the first time in Norway reported in wolf, a top predator from the terrestrial environment.Otters living in close proximity to human settlements and preying on the marine food ...

    • Selective processes for bioaccumulative up-take of persistent organic pollutants (POPs) in Arctic food webs 

      Carlsson, Pernilla Marianne (Doctoral thesis; Doktorgradsavhandling, 2013-11-21)
      The overall aim of the present study was to elucidate selective environmental up-take processes in Arctic food webs that lead to the bioaccumulation of persistent organic pollutants (POP) in food items consumed by Arctic indigenous people. In addition, this study aimed to increase the scientific understanding of the principles behind climate change related influences on transport processes of ...

    • Terrestrial inputs govern spatial distribution of polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) in an Arctic fjord system (Isfjorden, Svalbard) 

      Johansen, Sverre; Poste, Amanda; Allan, Ian; Evenset, Anita; Carlsson, Pernilla Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-17)
      <p>Considerable amounts of previously deposited persistent organic pollutants (POPs) are stored in the Arctic cryosphere. Transport of freshwater and terrestrial material to the Arctic Ocean is increasing due to ongoing climate change and the impact this has on POPs in marine receiving systems is unknown This study has investigated how secondary sources of POPs from land influence the occurrence and ...
