Mercury and selenium in harbor porpoise ( Phocoena phocoena) in norwegian waters
Abstract Concentrations of mercury and selenium have been determined in liver and kidney of 92 harbor porpoises ( Phocoena phocoena ) caught along the Norwegian coast. The hepatic and renal mercury concentrations ranged from 0.26 to 9.9 and 0.15 to 3.5 μg g −1 , respectively, whereas the correspondi...
