摘　　要：有机锡类化合物对环境生态和人类有很强内分泌毒性。其主要来源包括有机锡产品的生产和消耗、生物和化学甲基化效应。当前饮用水日益受到有机锡污染的严重威胁,主要原因有水源水的有机锡污染、PVC管材稳定剂的渗出和管网生物甲基化作用。通过分析提出解决饮用水有机锡问题应从3方面考虑,一是采用紫外光解或化学氧化处理受污染水源水,破坏水中有机锡化合物并消除其毒性;二是加强PVC管材质量要求,尽量采用低毒管材;三是定期更换给水管段以减少管网中生物甲基化导致的二次污染。Organotins are harmful to environmental zoology and human because of the endocrine toxicity. The production and consumption of organotins, biological and chemical methylation are the main sources in water. There are severe threatens of being polluted by organotins in face of potable water, and the source water pollution, the bleeding of PVC stabilizer agents and biological methylation in the pipe network system are leading reasons. The solvent of organotins problem in potable water is consisted by three aspects： First,UV or chemical oxidation could decompose organotins and eliminate their toxicity when treating micro-pulluted water. Second,the strict quality standard of PVC pipe must be guaranteed. Periodically replacement of pipes could efficiently reduce the secondary pollution caused by biological methylation.
