The relationship between polychlorinated biphenyls in blubber and levels of nematode infestations in harbour porpoises,Phocoena phocoena

Post-mortem examinations of harbour porpoises, Phocoena phocoena , regularly reveal heavy parasitic worm burdens. These same post-mortem records show varying levels of polychlorinated biphenyls (PCBs) accumulating in the blubber of porpoises. Although a number of papers have documented geospatial and temporal changes of PCBs and their detrimental effects on marine mammal health, as yet none have examined their role in determining nematode...
