Transfer rates and pattern of polychlorinated biphenyl isomers and congeners and p p' dde from mother to egg in adelie penguin pygoscelis adeliae


, : Transfer rates and pattern of polychlorinated biphenyl isomers and congeners and p p' dde from mother to egg in adelie penguin pygoscelis adeliae. Chemosphere 15(3): 343-352

Mother to egg transfer of PCB isomers and congeners and p,p'-DDE was examined in Adelie Penguin (Pygoscelis adeliae) from Antarctica. Transfer rate to a clutch of two eggs was estimated to be small, accounting to about 4.0% for both PCBs and p,p'-DDE to the burden in mother. No significant difference was found in the concentration ratios of individual PCB isomers and congeners between mother and egg, which apparently differed from those between mother and fetus of striped dolphin previously reported.
