Bioaccumulation of Fluorotelomer Sulfonates and Perfluoroalkyl Acids in Marine Organisms Living in Aqueous Film-Forming Foam Impacted Waters
Langberg, Håkon Austad; Breedveld, Gijs D.; Grønning, Hege Mentzoni; Kvennås, Marianne; Jenssen, Bjørn Munro; Hale, Sarah (Journal article; Peer reviewed, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ... -
Combined Effects of Perfluorooctane sulfonic acid (PFOS) and dissolved Carbon dioxide (CO2) on acute steroidogenic responses in the brain of Atlantic cod (Gadus morhua)
Langberg, Håkon Austad (Master thesis, 2014)Climate changes are often regarded as a concern for the future, but effects are already seen. Increased levels of atmospheric CO2 have resulted in increased levels of dissolved CO2 and a decreased pH in the ocean surface. ... -
Fate and transport of forever chemicals in the aquatic environment: Partitioning and biotransformation of mixtures of Per- and Polyfluoroalkyl Substances (PFAS) from different point sources and resulting concentrations in biota
Langberg, Håkon Austad (Doctoral theses at NTNU;2021:89, Doctoral thesis, 2021)Fate and transport of forever chemicals in the aquatic environment Per- and polyfluorinated alkyl substances (PFAS) are anthropogenic organic pollutants, defined as aliphatic substances that contain at least one ... -
The fate of poly- and perfluoroalkyl substances in a marine food web influenced by land-based sources in the Norwegian Arctic
Aasim, Ali M; Langberg, Håkon Austad; Hale, Sarah; Kallenborn, Roland; Mortensen, Åse-Karen; Hartz, William F; Ciesielski, Tomasz Maciej; McDonought, Carrie A.; Jenssen, Bjørn Munro; Breedveld, Gijs D. (Peer reviewed; Journal article, 2021)Although poly- and perfluorinated alkyl substances (PFAS) are ubiquitous in the Arctic, their sources and fate in Arctic marine environments remain unclear. Herein, abiotic media (water, snow, and sediment) and biotic media ... -
Fluorinated Precursor Compounds in Sediments as a Source of Perfluorinated Alkyl Acids (PFAA) to Biota
Langberg, Håkon Austad; Breedveld, Gijs D.; Slinde, Gøril Aasen; Grønning, Hege Mentzoni; Høisæter, Åse; Jartun, Morten; Rundberget, Thomas; Jenssen, Bjørn Munro; Hale, Sarah (Peer reviewed; Journal article, 2020)The environmental behavior of perfluorinated alkyl acids (PFAA) and their precursors was investigated in lake Tyrifjorden, downstream a factory producing paper products coated with per- and polyfluorinated alkyl substances ... -
Legacy and emerging per- and polyfluorinated alkyl substances (PFASs) in sediment and edible fish from the Eastern Red Sea
Ali, Aasim M; Sanden, Monica; Higgins, Christopher; Hale, Sarah; Alarif, Walied; Al-Lihaibi, Sultan; Ræder, Erik Magnus; Langberg, Håkon Austad; Kallenborn, Roland (Journal article; Peer reviewed, 2021) -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
Langberg, Håkon Austad; Arp, Hans Peter; Breedveld, Gijs D.; Slinde, Gøril Aasen; Høisæter, Åse; Grønning, Hege Mentzoni; Jartun, Morten; Rundberget, Thomas; Jenssen, Bjørn Munro; Hale, Sarah (Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ...
