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 in fish from the North East Atlantic: sources, bioaccumulation dynamics and co-occurrence with selenium

Azad, Atabak Mahjour (Doctoral thesis, 2019-09-26)

Mercury (Hg) is a global neurotoxin distributed at trace levels in the earth’s crust. Although Hg input from anthropogenic sources has been reduced in North America and Europe, in some other parts of the world the emission ...
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 ...
