Abstract

Triphenyltin hydroxide (TPTH) appears to be relatively stable in soil. Only minor partitioning into water occurred because of the insolubility of TPTH in water and its adsorption to soil. Residues in the water were also relatively stable. The concentration. of TPTH in the tissues of crayfish exposed to 1.0 ppm of TPTH in the soil was 0.1 ppm or 10% that of the environment. Crayfish exposed to 0.01 ppm of TPTH in the soil had 0.005 ppm TPTH in their tissues or 50% that of the environment. Greater than 80% of the residue in the muscle tissue appeared to be bound, and the extractable residue was essentially all TPTH. Similar binding was observed in visceral tissues and the extractable residue was 83% TP'IH, 9% diphenyltin dichloride, 4% bis-triphenlytin oxide, and 4% unknown. Following 28 days of exposure, the residue was persistent in the crayfish through a 24-day elimination period.
