A review of PFAS fingerprints in fish from Norwegian freshwater bodies subject to different source inputs
Langberg, Håkon Austad; Hale, Sarah; Breedveld, Gijs D.; Jenssen, Bjørn Munro; Jartun, Morten (Peer reviewed; Journal article, 2022)The extensive use of per- and polyfluorinated alkyl substances (PFAS) has resulted in many environmental point and diffuse sources. Identifying the source responsible for a pollution hot spot is vital for assessing remediation ... -
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 (Peer reviewed; Journal article, 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 ... -

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 ... -
Recycling of paper, cardboard and its PFAS in Norway
Langberg, Håkon Austad; Arp, Hans Peter Heinrich; Varela, Gabriela Castro; Asimakopoulos, Alexandros; Knutsen, Heidi (Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) have been used in paper products since the 1960s. PFAS emissions during the life cycle of these products have been substantial sources of these substances to the environment. Here, ... -

Using Passive Samplers to Track per and Polyfluoroalkyl Substances (PFAS) Emissions From the Paper Industry: Laboratory Calibration and Field Verification
Hale, Sarah E.; Canivet, Baptiste; Rundberget, Thomas; Langberg, Håkon Austad; Allan, Ian J. (Peer reviewed; Journal article, 2021)Per and polyfluoroalkyl substances (PFAS) are becoming more stringently regulated and as such, a more diverse suite of environmental monitoring methods is needed. In this work a polar organic chemical integrative sampler ...
