What is Occurrence and risk assessment of steroid estrogens in environmental water samples: A five-year worldwide perspective about?

The ubiquitous occurrence of steroid estrogens (SEs) in the aquatic environment has raised global concern for their potential environmental impacts. This paper extensively compiled and reviewed the available occurrence data of SEs, namely estrone (E1), 17a-estradiol (17a-E2), 17b-estradiol (17b-E2), estriol (E3), and 17a-ethinyl estradiol (EE2), based on 145 published articles in different regions all over the world including 51 countries and regions during January 2015eMarch 2020. The data regarding SEs concentrations and estimated 17b-estradiol equivalency (EEQ) values are then compared and analyzed in different environmental matrices, including natural water body, drinking and tap water, and wastewater treatment plants (WWTPs) effluent. The detection frequencies of E1, 17b-E2, and E3 between the ranges of 53%e83% in natural water and WWTPs effluent, and the concentration of SEs varied considerably in different countries and regions. The applicability for EEQ estimation via multiplying relative effect potency (REP i ) by chemical analytical data, as well as correlation between EEQ bio and EEQ cal was also discussed. The risk quotient (RQ) values were on the descending order of EE
