    • The impact of climate sensitive factors on the exposure to organohalogenated contaminants in an aquatic bird exploiting both marine and freshwater habitats 

      Bustnes, Jan Ove; Bårdsen, Bård-Jørgen; Herzke, Dorte; Bangjord, Georg; Bollinger, Eric; Bourgeon, Sophie; Schulz, Ralf; Fritsch, Clémentine; Eulaers, Igor (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-27)
      To assess how climate-sensitive factors may affect the exposure to organochlorines (OCs) and perfluoroalkyl substances (PFASs), we monitored concentrations in eggs of the common goldeneye (<i>Bucephala clangula</i>) over two decades (1999–2019) in central Norway. The goldeneye alternates between marine and freshwater habitats and is sensitive to climate variation, especially due to alterations in ...

    • Long-term monitoring of exposure to toxic and essential metals and metalloids in the tawny owl (Strix aluco): Temporal trends and influence of spatial patterns 

      Devalloir, Quentin; Fritsch, Clementine; Bangjord, Georg; Bårdsen, Bård-Jørgen; Bourgeon, Sophie; Eulaers, Igor; Bustnes, Jan Ove (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-10)
      As a result of regulatory decisions, atmospheric deposition of most toxic metals and metalloids (MEs) has decreased in Europe over the past few decades. However, little is known about how this reduction translates into exposure at higher trophic levels in the terrestrial environment where temporal trends may be spatially heterogeneous due to local current or legacy sources of emissions (e.g., industry) ...

    • Temporal Trends of Organochlorine and Perfluorinated Contaminants in a Terrestrial Raptor in Northern Europe Over 34 years (1986–2019) 

      Bustnes, Jan Ove; Bårdsen, Bård-Jørgen; Herzke, Dorte; Bangjord, Georg; Bourgeon, Sophie; Fritsch, Clémentine; Eulaers, Igor (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-21)
      Fourteen legacy organochlorine (OC) contaminants and 12 perfluoroalkyl substances (PFASs) were measured in eggs of tawny owls (Strix alueco) in central Norway (1986–2019). We expected OCs to have reached stable equilibrium levels due to bans, and that recent phase-out of some PFASs would have slowed the increase of these compounds. ∑OC comprised on average approximately 92% of the measured compounds, ...
