PESTAB. The distribution of DDT and polychlorinated biphenyl residues near 5 major municipal outfall systems in Southern California and a coastal and an island site were studied using Dover sole, Microstomus pacificus, as a bioindicator. The seven sites studied were Oxnard, Santa Monica, Palos Verdes, Orange County (north of Newport Beach), Dana Point, San Diego (Point Loma), and Santa Catalina Island. Even though major input of DDT and polychlorinated biphenyls had decreased during the years 1971 to 1975, fish collected in 1974-1975 showed no decline in muscle tissue concentrations of the two compounds. Decreases in the upper limits of DDT concentrations were noted at Palos Verdes and Santa Monica, the two most contaminated areas. Orange County and Dana Point showed increases in the upper limit of total DDT levels, indicating migration of the fish may have taken place. Changes in total polychlorinated biphenyls were similar to those for total DDT. Fish from Palos Verdes showed high chlorinated hydrocarbon liver-to- muscle tissue burden ratios when compared with fish from other areas.
