摘　　要：采用气相色谱质谱联用（GC －MS）、电感耦合等离子体质谱（ICP －MS）等方法对5个污水处理厂再生水中的162种微量有毒有害污染物进行了评价。在各种污染物中，酚类、酞酸酯、类固醇激素和金属类物质被检出。酚类物质的质量浓度为0．01～148 ng／L ，符合地表水环境质量标准，但三氯生、双酚 A 仍存在一定的生态风险；酞酸酯类物质的质量浓度为0．1～0．45μg／L ，符合地表水环境质量标准；类固醇激素的质量浓度为0．5～30 ng／L ，具有内分泌干扰效应，需优先控制；金属类物质的质量浓度为1～27μg／L ，满足污水排放标准和地表水环境质量标准。GC -MSICP - OEC ,ICP -MS ,alkaline digestion and colorimetric method are adopted to measure the trace toxic contaminants in reclaimed water .The qualitative analysis shows that phenol ,phthalate ,steroid and metal are the major toxic contaminants in reclaimed water which need to be controlled prior .From the result of quantitative analysis ,part of the phenol has been detected and the concentration is 0 .01 ~ 148 ng/L ,which accords with the GHZBI ,but there still exist some ecological risks in triclosan and bisphenol - A .Part of the phthalate ,which has been classified as precedence - con-trolled pollutant by America and China ,has been detected and the concentration is 0 .1 ~ 0 .45 μg/L .The concentration of the steroid is 0 .5 ~ 30 ng/L and it has endocrine disrupting effects that need to be controlled prior .Part of the metal has been detected and the concentration is 1 ~ 27 μg/L ,which meets the requirements of sewage discharge standard and GHZBI .
