概要 Tri-n-butyltin and its degradation products were measured in seawater samples between July 1994 and August 1995 at a marina that is located at a sequestered site of an enclosed harbor, Aburatsubo Bay, in Yokosuka, Japan. Dibutyltins, hydroxylated and oxo compounds of tributyltins and dibutyltins, carboxylated derivatives, and monobutyltin were observed in the summer months (from July to September) and only formed, if at all, in small quantities in the other seasons. Their structures were identified by comparison with synthesized authentic standards using GC/MIP/AED and four GC columns. The degradation products in the seawater in the summers between 1992 and 1995 and those in the oysters collected in the same area in the summer of 1992 showed very similar patterns. This result suggests that the degradation of tri-n-butyltin compounds may be attributable to microorganism flourishing in summer.
