Occurrence and tissue distribution of 33 legacy and novel per- and polyfluoroalkyl substances (PFASs) in Baikal seals (Phoca sibirica)
(Journal article; Peer reviewed, 2023)Per- and polyfluoroalkyl substances (PFASs) are bioaccumulative and associated with adverse effects in both wildlife and humans. The occurrence of 33 PFASs was assessed in the plasma, liver, blubber, and brain of 18 Baikal ... -
Occurrence of benzothiazole and benzotriazole in tunnel wash water
(Master thesis, 2023)De fleste av de 1200 tunnelene i Norge brukes daglig. All trafikk slipper ut forurensninger, enten direkte som biprodukter av drivstoff, eller indirekte som slitasje fra dekk. De fleste av disse forurensningene forblir ... -
Occurrence of Bisphenols and Benzophenone UV Filters in White-Tailed Eagles (Haliaeetus albicilla) from Smøla, Norway
(Journal article; Peer reviewed, 2021)There is a growing concern about the occurrence of bisphenols and benzophenone UV filters in natural ecosystems, while data are limited regarding their actual occurrence in wildlife species, especially in raptors. In this ... -
