我国饮用水水源内分泌干扰物的污染现状分析

Current Status of Endocrine Disrupting Chemicals Pollution in Drinking Water Source of China

我国作为饮用水水源的天然水体和部分饮用水水源地已受到内分泌干扰物的严重影响。文章分别从重金属类和有机类污染两个方面分析了我国饮用水源内分泌干扰物的污染现状,针对我国开展内分泌干扰物研究中存在的问题给出了建议对策并做出了展望。目前,我国七大水系以及华北、东南沿海地区的部分饮用水水源地都不同程度的受到了阿特拉津等有机氯农药污染为主,南方内分泌干扰物以多氯联苯(PCBs)、双酚(A)、邻苯二甲酸酯类、壬基苯酚等有机化工原料检出率最高。作为我国居民主要饮用水源的地下水,关于其内分泌干扰物的研究资料较少,还需引起高度重视。

Some water bodies and drinking water sources have been seriously affected by endocrine disrupting chemicals （EDCs）. Current status of endocrine disrupting chemicals both from organic and inorganic aspects was analyzed. According to the problems existing in the research of endocrine disrupting chemicals, several suggestions and prospects in the field were also proposed. The reported studies showed that 7 main river systems as well as some drinking water sources in northern and southeastern part of China have been polluted to certain extent. The pollution of organic endocrine disrupting chemicals is showing regional features, with organic chlorine pesticides such as hexachlorocyclohexane, DDT, chlordane and atrazine as the predominant pollutants in northern China, while in the southern part, PCBs, bisphenol-a, phthalate acid esters and nonyl phenol detected at the highest rate. More attentions should be paid to drinking water sources polluted by EDCs since there is no enough data on the issue.
