Polychlorinated biphenyls, dioxins, and furans in weaned, free-ranging northern elephant seal pups from central California, USA
The aim of this study was tomeasure persistent organic pollutants in northern elephant seals(NES], Mirounga angustirotris ). We obtained blubber biopsy samples from six healthy, newly weaned NES pups from Año Nuevo, California (USA). Contaminant levels were lower than those of other pinnipeds studie...
