    • Priority substances and emerging contaminants in selected Norwegian rivers – The River Monitoring Programme 2018 

      Allan, Ian; Jenssen, Marthe Torunn Solhaug; Braaten, Hans Fredrik Veiteberg (Research report; Forskningsrapport, 2019)
      Riverine inputs and direct discharges to Norwegian coastal waters in 2018 have been estimated in accordance with the OSPAR Commission’s principles. This report focuses on EU Water Framework Directive priority substances as well as river basin-specific pollutants (trace metals and organic pollutants) that were monitored with bottle sampling in water and biota sampling (fish). Levels observed were ...

    • 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)
