Dead newborn harbor seals were collected from Smith Island in the Strait of Juan de Fuca and from Gertrude Island in southern Puget Sound. A variety of chemical contaminants were measured in different kinds of tissue from seven harbor seal pups from each location. In addition to measurements of chemical concentrations, various tissues were also evaluated microscopically for histopathological abnormalities. Finally, two methods for determining the concentrations of PCBs and DDE in blubber tissues were compared. Concentrations of PCBs, lead and silver were significantly higher in the seals from Gertrude Island than those from Smith Island. However, the concentrations of PCBs in seal pups from both locations have declined significantly since testing began in 1972.
