Ho, Quang Tri; Bank, Michael; Mahjour Azad, Atabak; Nilsen, Bente Merete; Frantzen, Sylvia; Boitsov, Stepan; Måge, Amund; Kögel, Tanja; Sanden, Monica; Frøyland, Livar; Hannisdal, Rita; Hove, Helge Torbjørn; Lundebye, Anne-Katrine; Nøstbakken, Ole Jakob; Madsen, Lise (Journal article; Peer reviewed, 2021)Marine fish from the North East Atlantic Ocean (NEAO) are nutrient rich and considered a valuable economic resource. However, marine fish are also a major dietary source of several contaminants, including persistent organic ... -
Effects of geography and species variation on selenium and mercury molar ratios in Northeast Atlantic marine fish communities
Azad, Atabak Mahjour; Frantzen, Sylvia; Bank, Michael; Nilsen, Bente Merete; Duinker, Arne; Madsen, Lise; Måge, Amund (Peer reviewed; Journal article, 2019-11-01)Methylmercury (MeHg) is a potent neurotoxin that bioaccumulates in seafood. Co-occurrence of selenium (Se) may affect the bioavailability and toxicity of MeHg in organisms. Here we report the concentrations of total mercury ... -
Mercury bioaccumulation pathways in tusk (Brosme brosme) from Sognefjord, Norway: Insights from C and N isotopes
Mahjour Azad, Atabak; Frantzen, Sylvia; Bank, Michael; Madsen, Lise; Måge, Amund (Journal article; Peer reviewed, 2020-11)Seafood is the main source of methylmercury (MeHg) exposure for humans and elevated total mercury (Hg) concentrations have been reported in marine fish from Norwegian fjords compared with offshore areas. Hg in tusk fillets ... -
Rapid temporal decline of mercury in Greenland halibut (Reinhardtius hippoglossoides)
Bank, Michael; Frantzen, Sylvia; Duinker, Arne; Amouroux, David; Tessier, Emmanuel; Nedreaas, Kjell; Måge, Amund; Nilsen, Bente Merete (Journal article; Peer reviewed, 2021)Mercury (Hg) pollution in the ocean is an issue of global concern, however bioaccumulation regimes of this ubiquitous pollutant in marine apex predators have important knowledge gaps. Our fish length and stable isotope ...
