环境系统中有机锡化合物的分布和归宿

Distribution and Fate of Organotin Compounds in Environmental System

有机锡化合物是目前已知内分泌干扰物质中惟一的金属化合物,也是人为引入水环境中的最毒的化学物质之一,它对多种生物都有不同程度的毒害作用。由于有机锡化合物的广泛使用,大量有毒的有机锡化合物已通过各种途径进入环境生态系统中,从而对生态系统造成破坏。因此,研究有机锡化合物在自然环境系统中的迁移转化和分布,对了解这些污染物对生态系统的影响非常重要。总结了环境系统中有机锡化合物的迁移转化行为,包括生物甲基化、吸附、生物富集和降解等;概述了各种环境系统如水环境、沉积物、土壤、生物体中有机锡化合物的分布情况;简单介绍了人体对有机锡化合物的暴露情况。

Transferring of organotin compounds in environ-mental system has been summarized, and their distributions in different environmental systems such as water environment, sediments, soils and organisms were also reviewed. Finally, the routes of human exposed to organotin compounds and its pollution status were simply introduced.
