      Lohmann, Rainer; Cousins, Ian T.; DeWitt, Jamie; Glüge, Juliane; Goldenman, Gretta; Herzke, Dorte; Lindstrom, Andrew B.; Miller, Mark F.; Ng, Carla A.; Patton, Sharyle; Scheringer, Martin; Trier, Xenia; Wang, Zhanyun (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-12)
      Fluoropolymers are a group of polymers within the class of per- and polyfluoroalkyl substances (PFAS). The objective of this analysis is to evaluate the evidence regarding the environmental and human health impacts of fluoropolymers throughout their life cycle(s). Production of some fluoropolymers is intimately linked to the use and emissions of legacy and novel PFAS as polymer processing aids. There ...

    • Can plastic related chemicals be indicators of plastic ingestion in an Arctic seabird? 

      Collard, France; Tulatz, Felix; Harju, Mikael; Herzke, Dorte; Bourgeon, Sophie; Gabrielsen, Geir Wing (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-22)
      For decades, the northern fulmar (Fulmarus glacialis) has been found to ingest and accumulate high loads of plastic due to its feeding ecology and digestive tract morphology. Plastic ingestion can lead to both physical and toxicological effects as ingested plastics can be a pathway for hazardous chemicals into seabirds' tissues. Many of these contaminants are ubiquitous in the environment and the ...

    • Car tire crumb rubber: Does leaching produce a toxic chemical cocktail in coastal marine systems? 

      Halsband, Claudia; Sørensen, Lisbet; Booth, Andy; Herzke, Dorte (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-23)
      Crumb rubber granulate (CRG) produced from end of life tires (ELTs) is commonly applied to synthetic turf pitches (STPs), playgrounds, safety surfaces and walkways. In addition to fillers, stabilizers, cross-linking agents and secondary components (e.g., pigments, oils, resins), ELTs contain a range of other organic compound and heavy metal additives. While previous environmental impact studies on ...

    • Editorial: Environmental impacts and risks of car tire and styrene-butadiene rubber: microplastic pollution and contaminant transport 

      Halsband, Claudia; Sørensen, Lisbet; Khan, Farhan R.; Herzke, Dorte; Wagner, Stephan (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-04)
      Every year, almost 2 billion new vehicle tires are produced world-wide. At the same time >1 billion tires reach their end of life. During use, tire wear particles (TWPs) form through abrasion of the rubber material, and in contact with the road surface composites of both materials form tire and road wear particles (TRWPs). These emissions represent a large fraction of total microplastic pollution, ...

Our study aimed to investigate the occurrence of plastics in ...

    • The high persistence of PFAS is sufficient for their management as a chemical class 

      Cousins, Ian T.; Dewitt, Jamie C.; Glüge, Juliane; Goldenman, Gretta; Herzke, Dorte; Lohmann, Rainer; Ng, Carla A.; Scheringer, Martin; Wang, Zhanyun (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-29)
      Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic organic substances with diverse structures, properties, uses, bioaccumulation potentials and toxicities. Despite this high diversity, all PFAS are alike in that they contain perfluoroalkyl moieties that are extremely resistant to environmental and metabolic degradation. The vast majority of PFAS are therefore either non-degradable ...

    • 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 ...

      Glüge, Juliane; London, Rachel; Cousins, Ian T.; Dewitt, Jamie; Goldenman, Gretta; Herzke, Dorte; Lohmann, Rainer; Miller, Mark; Ng, Carla A.; Patton, Sharyle; Trier, Xenia; Wang, Zhanyun; Scheringer, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-05)
      Per- and polyfluoroalkyl substances (PFAS) are a class of substances for which there are widespread concerns about their extreme persistence in combination with toxic effects. It has been argued that PFAS should only be employed in those uses that are necessary for health or safety or are critical for the functioning of society and where no alternatives are available (“essential-use concept”). ...

    • Ingestion of car tire crumb rubber and uptake of associated chemicals by lumpfish (Cyclopterus lumpus) 

      Hägg, Fanny; Herzke, Dorte; Nikiforov, Vladimir; Booth, Andy; Sperre, Kristine Hopland; Sørensen, Lisbet; Egeness, Mari Jystad; Halsband, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      Car tire rubber constitutes one of the largest fractions of microplastics emissions to the environment. The two main emission sources are tire wear particles (TWPs) formed through abrasion during driving and runoff of crumb rubber (CR) granulate produced from end-of-life tires that is used as infill on artificial sports fields. Both tire wear particles and crumb rubber contain a complex mixture ...

    • Legacy perfluoroalkyl acids and their oxidizable precursors in plasma samples of Norwegian women 

      Miranda Fernandes Coelho, Ana Carolina; Cioni, Lara; Van Dreunen, Wendy; Berg, Vivian; Rylander, Karin Charlotta Maria; Urbarova, Ilona Halva; Herzke, Dorte; Sandanger, Torkjel M (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-12)
      Humans are exposed to perfluoroalkyl acids (PFAA) mainly through direct pathways, such as diet and drinking water, but indirect exposure also occurs when PFAA precursors break down to form legacy PFAA. Exposure to PFAA precursors raises particular concern, as neither the exposure nor the precursors themselves have been well described. In the present study, we aimed to assess the indirect contribution ...
