A long‐time‐scale, large‐space‐scale model of fate and bioaccumulation of PCB homologues in striped bass is constructed for the Hudson River estuary Of the total of 270 Mg (595,000 lb) of PCB discharged to the estuary proper from approximately 1947 through 1987, an estimated 66% volatilized, 6% went to sediment storage, and the remainder was lost by dredging and boundary transport. The striped‐bass model indicated that more than 90% of the fish PCB concentration is due to food‐chain effects. The upstream load from above Troy, New York, is estimated to be contributing about 20% to the current striped‐bass PCB concentrations.
