摘要

首次对重庆市饮用水水厂中有机化合物的赋存状态和去向进行了调查。水样采用固相微萃取(SPME)法提取，气相色谱(GC)质谱(MS)法测定。结果表明:重庆市饮用水水厂存在有机锡污染，以MBT为主，最高水平为120.78ngSn/l;有时发现DBT、MPT和DPT。偶见少量内分泌干扰物TPT (2.77 ngSn/l)，未见TBT。常规的水处理工艺不能有效去除有机锡。

Occurrence of organotins in drinking water treatment in Chongqing

The occurrence and fate of organotins compounds in drinking water plant in Chongqing of southern China was investigated for the first time. Water samples were extracted by solid phase micro-extraction (SPME) and measured by gas chromatograph (GC) with mass spectrum (MS). Results showed the presence of organotin pollution in drinking water plant in Chongqing and most of organotins was MBT with the highest level of 120.78ngSn/l. Sometimes DBT, MPT and DPT were found. Little endocrine disruptors of TPT (2.77 ngSn/l) was also found occasionally, but TBT was not found. Conventional water treatment process could not removed organotins effectively.
