Tri-n-butyltin and its degradation products were measured inseawater samples between July 1994and August 1995 at a marina that is located at a sequestered site of anenclosed harbor, AburatsuboBay, in Yokosuka, Japan. Dibutyltins, hydroxylated and oxocompounds of tributyltins anddibutyltins, carboxylated derivatives, and monobutyltin were observedin the summer months (fromJuly to September) and only formed, if at all, in small quantities inthe other seasons. Theirstructures were identified by comparison with synthesized authenticstandards using GC/MIP/AEDand four GC columns. The degradation products in the seawater inthe summers between 1992and 1995 and those in the oysters collected in the same area in thesummer of 1992 showed verysimilar patterns. This result suggests that the degradation oftri-n-butyltin compounds may beattributable to microorganism flourishing in summer.Keywords: Tributyltin; seawater; degradation; chemical species; seasonalvariation; organotincompounds
