    • Impacts of a warming climate on concentrations of organochlorines in a fasting high arctic marine bird: Direct vs. indirect effects? 

      Bustnes, Jan Ove; Bårdsen, Bård-Jørgen; Moe, Børge; Herzke, Dorte; Ballesteros, Manuel; Fenstad, Anette; Borgå, Katrine; Krogseth, Ingjerd Sunde; Eulaers, Igor; Skogeng, Lovise Pedersen; Gabrielsen, Geir Wing; Hanssen, Sveinn Are (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-30)
      The present study examined how climate changes may impact the concentrations of lipophilic organochlorines (OCs) in the blood of fasting High Arctic common eiders (Somateria mollissima) during incubation. Polychlorinated biphenyls (PCBs), 1-dichloro-2,2-bis (p-chlorophenyl) ethylene (p,p′-DDE), hexachlorobenzene (HCB) and four chlordane compounds (oxychlordane, trans-chlordane and trans- and ...

    • Modelling PCB-153 in northern ecosystems across time, space, and species using the nested exposure model 

      Krogseth, Ingjerd Sunde; Breivik, Knut; Frantzen, Sylvia; Nilsen, Bente Merete; Eckhardt, Sabine; Nøst, Therese Haugdahl; Wania, Frank (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      There is concern over possible effects on ecosystems and humans from exposure to persistent organic pollutants (POPs) and chemicals with similar properties. The main objective of this study was to develop, evaluate, and apply the Nested Exposure Model (NEM) designed to simulate the link between global emissions and resulting ecosystem exposure while accounting for variation in time and space. NEM, ...

    • Reducing sampling artifacts in active air sampling methodology for remote monitoring and atmospheric fate assessment of cyclic volatile methylsiloxanes 

      Warner, Nicholas Alexander; Nikiforov, Vladimir; Krogseth, Ingjerd Sunde; Bjørneby, Stine Marie; Kierkegaard, Amelie; Bohlin-Nizzetto, Pernilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-04)
      Active sampling methodology for atmospheric monitoring of cyclic volatile methylsiloxanes (cVMS) was improved to reduce sampling artifacts. A new sorbent, ABN Express (ABN), was evaluated for storage stability and measurement accuracy. Storage stability of cVMS on ABN showed less than 1% degradation of the individual <sup>13</sup>C-labelled octamethylcyclotetrasiloxane (<sup>13</sup>C<sub>4</sub>-D4), ...

    • Spatial distribution of Dechlorane Plus and dechlorane related compounds in European background air 

      Skogeng, Lovise Pedersen; Halvorsen, Helene Lunder; Breivik, Knut; Eckhardt, Sabine; Herzke, Dorte; Moeckel, Claudia; Krogseth, Ingjerd Sunde (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-10)
      The highly chlorinated chemical Dechlorane Plus (DP) was introduced as a replacement flame retardant for Mirex, which is banned through the Stockholm Convention (SC) for its toxicity (T), environmental persistence (P), potential for bioaccumulation (B) and long-range environmental transport potential (LRETP). Currently, Dechlorane Plus is under consideration for listing under the Stockholm Convention ...
