摘　　要：采用重组基因酵母法检测了北京市16个污水处理厂污泥的雌激素、雄激素和孕激素效应.结果表明,各污水厂污泥中均可检测到雌激素受体诱导效应,范围在0.587～6.76ngEEQ·g-(1dw)之间.各水厂污泥均未检测出雄激素诱导效应和孕激素诱导效应,大部分污水厂污泥样品表现出较明显的雄激素抑制效应和较强的孕激素抑制效应.与国外相比,北京市污水厂污泥中的雌激素活性值相对较低.堆肥处理不能有效去除雌激素类物质和孕激素抑制物质,但对雄激素抑制物质的去除明显.This study tested for estrogenic effect,androgenic effect and progestogenic effect of sewage sludge from sixteen sewage treatment plants in Beijing using a recombinant yeast bioassay.Estrogenic activity can be detected for all the sewage sludge,with rang from 0.587 to 6.76ngEEQ·g-1（dw）of estradiol equivalent.None of samples showed androgenic activity and progestogenic activity.However,major part of samples showed obviously inhibitory effect for androgen,and strong inhibitory effect for progestogen.In general,the estrogenic activity in the sludge in Beijing was lower than those reported elsewhere.The composting process could not remove efficiently estrogen-like chemicals or progestogenic inhibitors,but could remove efficiently androgenic inhibitor from sewage sludge.
