摘要: The whole-body burdens and concentrations of ZDDT (the sum p,p,′-DDE p,p′-DDT) PCBs in the Weddell seal, Leptonychotes weddelli, caught near Syowa Station, Antarctica, were determined by detailed biometric measurements their organs tissues analyses them. concentration levels seals much lower than those various species marine mammals from other oceans. low may be attributable to these chemicals food sea water under antarctic fast ice. However, ratio between organisms ice was higher ocean ecosystems.
