Organotin problem in potable water and its countermeasures
饮用水的有机锡问题及对策

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.
