Lipophilicity of PCBs and fatty acids determines their mobilisation from blubber of weaned northern elephant seal pups.
Polychlorinated biphenyls (PCBs) exhibit lipophilic properties that lead to their bioaccumulation in adipose tissue. Following PCB exposition, northern elephant seals (Mirounga angustirostris) concentrate high amounts of these pollutants in their large adipose tissue stores. During lipolytic periods...
