Cadmium in brown crab Cancer pagurus. Effects of location, season, cooking and multiple physiological factors and consequences for food safety
Wiech, Martin; Frantzen, Sylvia; Duinker, Arne; Rasinger, Josef Daniel; Måge, Amund (Journal article; Peer reviewed, 2020)Brown crab Cancer pagurus is appreciated as seafood in several European countries. However, cadmium levels in crabs can be elevated and their consumption may pose a hazard for human health. To assess if cadmium poses a ... -
Cadmium in the shore crab Carcinus maenas along the Norwegian coast: geographical and seasonal variation and correlation to physiological parameters
Knutsen, Heidi; Wiech, Martin; Duinker, Arne; Måge, Amund (Peer reviewed; Journal article, 2018-04)Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67° N, compared to regions further south along the Norwegian ... -
Effects of cooking and freezing practices on the distribution of cadmium in different tissues of the brown crab (Cancer pagurus)
Wiech, Martin; Vik, Eirin; Duinker, Arne; Frantzen, Sylvia; Bakke, Snorre; Måge, Amund (Peer reviewed; Journal article, 2017-05)Increased cadmium concentrations in claw meat were demonstrated after cooking and freezing practices of whole brown crabs. This was investigated in crabs from two different locations along the Norwegian coast, one with ... -
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 ... -
Spatial distribution of mercury in seawater, sediment, and seafood from the Hardangerfjord ecosystem, Norway
Azad, Atabak Mahjour; Frantzen, Sylvia; Bank, Michael; Johnsen, Ingrid Askeland; Tessier, Emmanuel; Amouroux, David; Madsen, Lise; Måge, Amund (Peer reviewed; Journal article, 2019-06-01)Hardangerfjord is one of the longest fjords in the world and has historical mercury (Hg) contamination from a zinc plant in its inner sector. In order to investigate the extent of Hg transferred to abiotic and biotic ... -
Tracing simultaneous cadmium accumulation from different uptake routes in brown crab Cancer pagurus by the use of stable isotopes
Wiech, Martin; Amlund, Heidi; Jensen, Karl Andreas; Aldenberg, Tom; Duinker, Arne; Måge, Amund (Peer reviewed; Journal article, 2018-05-24)High concentrations of cadmium in brown crab are an issue of food safety, and large variations between different areas have been found. To investigate the relative importance of dietary and aqueous uptake regarding the ...
