The estrogenic potentials of leachate samples collected at Laogang Sanitary Landfill in Shanghai, China were measured together with the associated dissolved organic matter (DOM) in leachate samples. Over 99% of the DOM in fresh leachate was removed upon 3-7 years of landfill, leaving only DOM with strong fluorescent activity. Anoxic or aerobic treatment of landfill leachate can further degrade DOM of MW<300 Da and transform those with fluorescent activity of MW>10(5) Da to those of 2000-10(5) Da. Neither landfilling nor storage in anoxic pond effectively removed estrogenic potential of leachate. Fractionation test revealed that residual organic matters of MW 3000-14000 Da and of <600 Da with high UV254 contributed most of the estrogenic activities in leachate. Aerobic SBR treatment considerably reduced the estrogenic potential of these organic matters in leachate.
对在中国上海老港卫生填埋场采集的渗滤液样品的雌激素潜力及其相关的溶解有机物（DOM）进行了测定。新鲜渗滤液中超过99%的DOM在填埋3至7年后被去除，仅留下具有强荧光活性的DOM。对垃圾渗滤液进行缺氧或好氧处理可进一步降解分子量小于300 Da的DOM，并将分子量大于10⁵ Da的具有荧光活性的DOM转化为2000至10⁵ Da的DOM。填埋和在缺氧池中储存均不能有效去除渗滤液的雌激素潜力。分级试验表明，分子量为3000至14000 Da以及小于600 Da且具有高UV254的残留有机物对渗滤液中的大部分雌激素活性起了主要作用。好氧SBR处理大大降低了渗滤液中这些有机物的雌激素潜力。
