北京工业废水和城市污水环境激素污染状况调查

利用固相萃取前处理技术和高效液相色谱、气相色谱方法，分析研究北京地区重点污染源排水(包括工业废水和城市污水)中主要环境激素(邻苯二甲酸酯、有机氯农药、有机氮农药、有机磷农药、菊酯类农药、烷基酚和双酚A)的残留状况. 调查分析了分布在北京市10个区县的污水处理厂、化工行业、冶金焦化行业、医院及其洗涤中心、印钞行业、食品加工行业和制药行业等7类22个单位排水中的8种邻苯二甲酸酯，17种有机氯农药，7种有机氮和有机磷农药，4种菊酯类农药，4种烷基酚及双酚A共40种环境激素类物质的质量浓度. 并着重分析了污水处理厂进、出水中的环境激素的浓度水平. 结果表明，北京地区工业废水和城市污水中广泛存在着环境激素污染，但其质量浓度并未超过现行排放标准. 

Investigation on Status of Environmental Hormone Pollution in the Industrial Wastewater and Urban Sewage in Beijing

The residual levels of main environmental hormones e.g. PAEs, OCPs, ONPs, OPPs, Alkylphenol and Bisphenol-A in the industrial wastewater and urban sewage from main polluting sources in Beijing were investigated, using solid phase extraction (SPE) and high performance liquid chromatography (HPLC) and gas chromatography (GC). The residual levels of 40 environmental hormones, including 8 kinds of PAEs, 17 kinds of OCPs, 7 kinds of ONPs and OPPs, 4 kinds of tyrethrin pesticides, 4 kinds of Alkylphenol and Bisphenol-A in the wastewater from 22 majorsources of 7 classes, i.e. urban sewage plants, hospitals with their washing centers, and chemical, metallurgical and coking, banknote printing, food processing and pharmaceutical industries in 10 districts and counties were surveyed and analyzed. The residues of the environmental hormones in influent and effluent of the sewage treatment plants in Beijing were focused. The results indicated that there were widely environmental hormones pollution in almost all the industrial wastewater and urban sewage, but they do not exceed the existing discharge standards.
