Inter-species differences in polychlorinated biphenyl patterns from five sympatric species of odontocetes: can PCBs be used as tracers of feeding ecology?
Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common dolphin (Delphinus delphis), long-finned pilot whale (Globicephala melas), harbour po...
