Bioaccumulation of mercury and transcriptional responses in tusk (Brosme brosme), a deep-water fish from a Norwegian fjord
Olsvik, Pål Asgeir; Mahjour Azad, Atabak; Yadetie, Fekadu (Peer reviewed; Journal article, 2021)High concentrations of mercury (Hg) have been documented in deep-water fish species from some Norwegian fjords. In this study, tusk (Brosme brosme) was sampled from four locations in the innermost parts of Sognefjorden in ... -
Co-occurrence of contaminants in marine fish from the North East Atlantic Ocean: Implications for human risk assessment
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 (Peer reviewed; Journal article, 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 ... -
Congener-specific accumulation of persistent organic pollutants in marine fish from the Northeast Atlantic Ocean
Ho, Quang Tri; Frantzen, Sylvia; Nilsen, Bente Merete; Nøstbakken, Ole Jakob; Mahjour Azad, Atabak; Duinker, Arne; Madsen, Lise; Bank, Michael (Peer reviewed; Journal article, 2023)Bioaccumulation of persistent organic pollutants (POPs) in marine fish may pose a health risk to human consumers. Using data from ∼8400 individuals of 15 fish species collected in the North-East Atlantic Ocean (NEAO), we ... -
Differences in nutrient and undesirable substance concentrations in Maurolicus muelleri across the Bay of Biscay, Norwegian fjords, and the North Sea
Zhu, Yiou; Mahjour Azad, Atabak; Kjellevold, Marian; Bald, Carlos; Iñarra, Bruno; Alvarez, Paula; Boyra, Guillermo; Berntssen, Marc HG; Madsen, Lise; Wiech, Martin (Peer reviewed; Journal article, 2023)We are having pressing issues of global food insecurity and malnutrition. Mesopelagic communities in the North Atlantic have been estimated to have high biomasses of organisms. Some of these low-trophic organisms are known ... -
Effects of geography and species variation on selenium and mercury molar ratios in Northeast Atlantic marine fish communities
Mahjour Azad, Atabak; Frantzen, Sylvia; Bank, Michael; Nilsen, Bente Merete; Duinker, Arne; Madsen, Lise; Måge, Amund (Journal article; Peer reviewed, 2019)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 (Peer reviewed; Journal article, 2020)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 ... -
Metabolic effects of diet containing blue mussel (Mytilus edulis) and blue mussel-fed salmon in a mouse model of obesity
