摘    要:残留在自来水中的内分泌干扰物质的来源主要包括水源污染,配水管网及这些化合物质在氯消毒过程中的副产物,水源中检出频率较高的是壬基苯酚,双酚A、4-t-辛基苯酚、邻苯二甲酸乙基已基酯及来自人畜的雌酮,配水管网中的物质主要是作为塑料添加剂的壬基苯酚,双酚A等,在氯消毒过程中,双酚A及NP可以分解产生多种副产物,用酵母Two-hybrid法对这些副产物的内分泌干扰作用进行了研究,表明双酚A的副产物具有雌激素协同作用,而NP的副产物则具有雌激素拮抗作用,检测出我国某河流及自来水的内分泌干扰活性。

关 键 词:自来水  内分泌干扰物质  壬基酚  双酚A  水源

Abstract:Endocrine disrupting compounds in tap water mainly stem from the pollution of raw water for water supply, concrete tank and lining of still pipe in water supply system, and chlorination process. Main endocrine disrupting compounds detected in raw water are of nonylphenol, bisphenol A and di(2-ethylhexyl) phthalate. In addition, bisphenol A and nonylphenol are main compounds released from the lacquer coatings of concrete tank and lining of still pipe in water supply system. Several byproducts of bisphenol A and nonylphenol were found in chlorination. The results based on the yeast two-hybrid system show that while the byproducts of bisphenol A elicited th estrogenious agonist, that of nonylphenol elicited estrogenious antagonist. A tap water and it's raw water also elicited endocrine disrupting activity.
Keywords:Tap water  Endocrine Disrupting compounds  nonylphenol  bisphenol A  yeast two-hybrid
