In this article, we choose four typical phenols 2,4-Dichlorophenol, pentachloropheno,4-nonylphenol,bisphenol and four steroids types environmental hormones estrone,ethinyl estradiol,estradiol,estriol as the objects of my study.We use solid phase extraction and gas chromatograph-mass spectrometer to determination,and recearch deposit and assign rules of phenol-alcohols environmental hormones in the middle of Weihe river,and through the combined with ultrafiltration-nanofiltration to receach its separation efficiency,main conclusions as follows. In the different time,we analyzed and detected phenol-alcohols environmental hormones in the middle of Weihe river,the results show that pullution of phenol-alcohols substances is quite serious,consistency of 2,4-Dichlorophenol is 0.009～3.899μg/L, pentachloropheno is 0.003 ～ 55.481μg/L, 4-nonylphenol is 0.004 ～ 2.227μg/L, bisphenol is 0.055～128.122μg/L, in alcoholic substances,consistency of estrone 0.027～ 6.679μg/L, ethinyl estradiol is 0.010～11.409μg/L, estradiol is 0.015～18.546μg/L, estriol is 0.034～18.674μg/L. In these results, the consistency of PCP,BPA and E2 is beyond the national environmental quality standards for surface water, and the consistency of rest hormone substances are also beyond the investigation results of surface water concentrations abroad.As the seasons change,changes in water content of phenolic alcohols
