    • Effects of the sea lice bath treatment pharmaceuticals hydrogen peroxide, azamethiphos and deltamethrin on egg-carrying shrimp (Pandalus borealis) 

      Frantzen, Marianne; Bytingsvik, Jenny; Tassara, Luca; Reinardy, Helena C.; Refseth, Gro Harlaug; Watts, Ellie J.; Evenset, Anita (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-16)
      This study investigated effects of sea lice pharmaceuticals on egg-bearing deep-water shrimp (Pandalus borealis). Both mortality and sub-lethal effects (behavior, embryo development, and reproductive output) were studied for each of three pharmaceuticals alone and in different sequential combinations. The most severe effect was observed for deltamethrin where 2 h exposure to 330 times diluted treatment ...

    • Expression of DNA repair genes in arctic char (Salvelinus alpinus) from Bjørnøya in the Norwegian Arctic 

      Inderberg, Helene; Neerland, Eirik D.; Mcpartland, Molly; Sparstad, Torfinn; Bytingsvik, Jenny; Nikiforov, Vladimir A; Evenset, Anita; Krøkje, Åse (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-08)
      High levels of organochlorines (OCs) have been measured in arctic char (<i>Salvelinus alpinus</i>) from Lake Ellasjøen on Bjørnøya, Norway (74.30°N, 19.0°E). In a nearby lake, Laksvatn, the OC-levels in arctic char were low. A previous study has shown that char from Ellasjøen had significantly higher levels of DNA double strand breaks (DSBs) than char from Lake Laksvatn. Even though there is increasing ...

    • Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton 

      Carrasco, Nathalie; Mcgovern, Maeve; Evenset, Anita; Søreide, Janne E.; Arts, Michael T.; Jonsson, Sofi; Poste, Amanda Elizabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation ...

    • 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 ...
