The report describes the use of solid-phase extraction(SPE)and LC/MS/MS to investigate the occurrence and distribution of 4 estrogens(estrone,17 β-estradiol,estriol,and 17 α-ethynylestradiol)and 3 anti-inflammatorie...The report describes the use of solid-phase extraction(SPE)and LC/MS/MS to investigate the occurrence and distribution of 4 estrogens(estrone,17 β-estradiol,estriol,and 17 α-ethynylestradiol)and 3 anti-inflammatories(ibuprofen,ketoprofen and naproxen)in the Zhangweinanyun River System(China).Relatively higher concentrations were observed for estrone,17 α-ethynylestradiol,and ketoprofen in the Wei Canal than in the Wei River and in the Zhangweixin River.The study suggested that there is a potential ecological risk of male fish feminization from estrogens in the Zhangweinanyun River System.展开更多
