Environmental Contaminants and Biochemical Responses in Flatfish from the Hvaler Archpelago in Norway

Concentrations of selected PAHs, PCBs, heavy metals, dioxins and furans, and organochlorine pesticides were determined in muscle and liver of three flatfish species sampled in the Hvaler archipelago, Norway. Only low levels of polychlorinated dibenzodioxins/polychlorinated dibenzodifurans, cadmium,...

Description
Summary:Concentrations of selected PAHs, PCBs, heavy metals, dioxins and furans, and organochlorine pesticides were determined in muscle and liver of three flatfish species sampled in the Hvaler archipelago, Norway. Only low levels of polychlorinated dibenzodioxins/polychlorinated dibenzodifurans, cadmium, and lead were detected. PCB levels were higher in fish from inner sites of the archipelago than in those from a reference site. The pollution gradient toward the Glomma estuary was correlated with increased cytochrome P450 1A1 activity in liver fractions. The results reflect different regional pollution histories and indicate the utility of biochemical effect indices in monitoring studies.
