Green sunfish (Lepomis cyanellus Raf.) were placed in jars of aged tap water to which was added one of three PCBs (2,2',5-trichlorobiphenyl, 2,2',5,5'-tetrachlorobiphenyl, or 2,2','-pentachlorobiphenyl), DDT, or DDE at dose levels of 1 or 3 ppb. The tissues of the fish were analyzed for residues using thin-layer chromatography. DDT, DDE, and the pentachlorobiphenyl had similar uptake curves in regard to retention of the compounds after they were added to the environment. The retention of the tetrachlorobiphenyl was somewhat less; a few days after the peak concentration was reached in the tissues, the levels began to drop. With the trichlorobiphenyl, the tissue concentration dropped sharply after reaching a peak; this indicates that the green sunfish is able to transform the trichlorobiphenyl into polar species.
