Excretion of bis(tri‐n‐butyltin)oxide and triphenyltin chloride from CARP

Abstract
Excretion of bis(tri‐n‐butyltin)oxide ((Bu3Sn)2O) and triphenyltin chloride (Ph3SnCl) from carp was studied in clean water for 3 days after bioconcentration of these compounds in the test tank for 7 days. The concentrations of (Bu3Sn)2O and Ph3SnCl in muscle decreased, but those in viscera (liver, kidney and gallbladder) did not change during the 3 days excretion experiment. The excretion rate constants were 0.40 day‐1 for (Bu3Sn)2O and 0.50 day‐1 for Ph3SnCl assuming their processes to be first‐order kinetics.
