Release of domestic sewage leads to accumulation of xenoestrogens in holding waters, especially in closed or semi-enclosed waters such as lakes. In the study, the occurrence, distribution, estrogenic activity and risk of eight xenoestreogens were evaluated in Lake Donghu, China. Nonylphenol (NP), octylphenol (OP), and bisphenol A (BPA) were identified as the main xenoestrogens ranging from tens of ngL(-1) (in the surface water) or ng g(-1)dw (in the suspended particles and sediment) to tens of μgL(-1) or μg g(-1)dw. The sum of 17β-estradiol equivalents (∑EEQs) ranged from 0.32 to 45.02 ngL(-1) in the surface water, 0.53 to 71.86 ng g(-1)dw in the suspended particles, and 0.09 to 24.73 ng g(-1)dw in the sediment. Diethylstilbestrol (DES) was determined as the main contributor to ∑EEQs followed by NP. The risk assessment showed a higher risk in the surface water than in the suspended particles and sediment in such domestic sewage-holding lake.
生活污水的排放会导致蓄水中的外源性雌激素累积，尤其是在湖泊等封闭或半封闭水域。本研究评估了中国东湖中 8 种外源性雌激素的发生、分布、雌激素活性及其风险。壬基酚（NP）、辛基酚（OP）和双酚 A（BPA）被鉴定为主要的外源性雌激素，其浓度范围从数十纳克/升（表层水中）或纳克/克干重（悬浮颗粒物和沉积物中）到数十微克/升或微克/克干重。表层水中的 17β-雌二醇当量（∑EEQs）的范围为 0.32 至 45.02 纳克/升，悬浮颗粒物中的范围为 0.53 至 71.86 纳克/克干重，沉积物中的范围为 0.09 至 24.73 纳克/克干重。己烯雌酚（DES）是∑EEQs 的主要贡献者，其次是 NP。风险评估显示，在这种生活污水蓄水中，表层水的风险高于悬浮颗粒物和沉积物。
