Abstract：
The risk quotient (RQ) related to Estrone (E1), 17β-E2 (E2), Estriol (E3) and 17α-ethynylestradiol (EE2) in sediment of water resources in China was calculated using Monte Carlo Simulation (MCS) method. Fifty-four papers with 64 data-reports included in our study. The rank order of steroid hormones in sediment based on log-normal distribution in MCS was E1 (3.75 ng/g dw) > E3 (1.53 ng/g dw) > EE2 (1.38 ng/g dw) > E2 (1.17 ng/g dw). According to results, concentration of steroid hormones including E1, E2 and E3 in sediment of Erhai lake, northern Taihu lake and Dianchi river was higher than other locations. The rank order of steroid hormones based on percentage high risk (RQ > 1) was EE2 (87.00%) > E1 (70.00%) > E2 (62.99%) > E3 (11.11%). Hence, contamination control plans for steroid hormones in sediment of water resources in China should be conducted continuously.
摘要：
与Estrone(E1)相关的风险商(RQ)，17β-E2(E2),利用蒙特卡罗模拟(MCS)方法计算了中国水资源沉积物中的雌三醇(E3)和17α-乙炔基雌二醇(EE2)。我们的研究包括54篇论文和64份数据报告。根据MCS中对数正态分布，沉积物中类固醇激素的排列顺序为E1（3.75ng/gdw）>E3（1.53ng/gdw）>EE2（1.38ng/gdw）>E2（1.17ng/gdw）。根据结果,洱海沉积物中类固醇激素E1，E2和E3的浓度，太湖北部和滇池高于其他地区。根据高危百分比（RQ>1），类固醇激素的等级顺序为EE2（87.00％）>E1（70.00％）>E2（62.99％）>E3（11.11％）。因此，中国水资源沉积物中类固醇激素的污染控制计划应持续进行。
