Fluctuating concentrations of organochlorine pollutants during a breeding season in two Antarctic seabirds: Adelie penguin and southern fulmar
Abstract During the reproductive cycle significant fluctuations of concentrations of organochlorine pollutants were detected in blood and uropygial oil from Adélie penguins ( Pygoscelis adeliae ) and southern fulmars ( Fulmarus glacialoides ) from Hop Island, Antarctica. In the Adélie penguin, conce...
