Abstract | The brief report summarizes the concentrations of PCB's in oyster tissue (Crassostrea virginica) observed from April 1969 to June 1976 at three locations in the Escambia Bay estuary, following elimination of an accidental leak of Aroclor 1254 from an industrial site. Data showed that PCB's in oyster tissues decreased after the leak was eliminated, but a steady-state concentration was reached. No Aroclor 1254 was detectable in water at stations sampled, but sediments were found to contain relatively low amounts (>0.31 ppm) in 1970 and 1971. The study demonstrates the persistence of PCB's long after point-source discharges are eliminated. |
