Organotin Compounds in the Three Gorges Reservoir Region of the Yangtze River
Tributyltins (TBT) are known endocrine disrupting chemicals (EDCs). It was reported that TBT at concentrations of more than 7 ng Sn/l would induce juvenile Buccium undatum to develop a penis and a vas deferens, i.e. imposex (Ten Hallers-Tjabbes et al. 2003). TBT in aquatic systems were also reported to be related to various symptoms such as thickening of shell and failure of spat in oyster (Alzieu et al.19986), impotence of neogastropods (Gibbs et al. 1991a), reduction of dogwhelk population (Gibbs et al. 1991b), and immunological dysfunction in fish (Suzuki et al. 1992).
