description: This paper summarizes recent work on the metabolism of tributyltin (TBT) by marine animals and how this metabolism may relate to some of the observed effects. Fish and crustaceans have an active cytochrome P-450 dependent mono-oxygenase system which oxidizes TBT to a series of hydroxylated derivatives. These hydroxylated derivatives are conjugated to sulfate or carbohydrate by phase 2 enzyme systems which facilitates the rapid elimination of TBT from the animal. Mollusks have low cytochrome P-450 content and mixed function oxygenase activity which results in TBT accumulation because of the low TBT metabolism rate. Some of the TBT effects observed for mollusks include imposex in stenoglossan gastropods, oyster shell thickening, reduced growth rates in mussels and breakdown of sexual differentiation, oogenesis and egg production in Ostrea edulis .
