| 中文摘要 |
| 采用固相萃取-超高效液相色谱串联质谱法（SPE-UPLC-MS/MS）分析了无锡-常州地区地下水中4类（性激素、孕激素、糖皮质激素和酚类激素）22种典型内分泌干扰物（EDCs）的赋存特征.结果表明，共有20种EDCs被检出，以双酚A（BPA）、雌酮（E1）、雌二醇（E2）和炔雌醇（EE2）为主，检出率均在90%以上，其次是雌三醇（E3）和甲基泼尼松龙（Meprednl），检出率分别为67.7%和48.4%.BPA平均浓度最高，为4.95 ng·L-1，其次是甲基泼尼松龙、雌二醇、泼尼松龙（Prednl）、丙酸睾酮（TES-pro）和醋酸甲地孕酮（MA），平均浓度分别为2.84、0.71、0.64、0.58和0.53 ng·L-1.各点位总浓度范围在0.38~147.35 ng·L-1之间，高浓度点主要集中在常州市新北区、溧阳市和钟楼区.结合主成分分析（PCA）和采样点周边污染源对潜在来源进行解析，结果表明地下水中EDCs主要来源于生活污水、养殖和工业废水，其次为医疗废水.非致癌健康风险评价结果表明，研究区地下水中EDCs非致癌风险整体处于较低水平，饮水途径引起的风险水平大于皮肤暴露，EE2的非致癌风险最高，应作为重点监控对象. |
| 英文摘要 |
| The concentrations of 22 endocrine disrupting chemicals, including 4 categories of sex hormones, progesterones, glucocorticoids, and phenolic hormones, in groundwater of Wuxi-Changzhou were analyzed using solid-phase extraction and ultra-performance liquid chromatography tandem mass spectrometry. The results indicated that 20 EDCs were detected, among which bisphenol A (BPA), estrone (E1), estradiol (E2), and 17α-ethinyl estradiol (EE2) were the main components with detection ratios greater than 90%, followed by estriol (E3) and methyl-prednisolonel (Meprednl), which had detection rates 67.7% and 48.4%, respectively. The average concentration of BPA was the highest (4.95 ng·L-1), followed by that of Meprednl, E2, prednisolone (Prednl), testosterone propionate (TES-pro), and megestrol-acetate (MA; 2.84, 0.71, 0.64, 0.58, and 0.53 ng·L-1, respectively). The total concentration in each site ranged from 0.38 to 147.35 ng·L-1. The sites with higher concentration were mainly distributed in the Xinbei District, Liyang City, and the Zhonglou District of Changzhou City. The potential sources were analyzed by a principal component analysis (PCA) combining the point sources near sample sites. The results showed that domestic sewage, aquaculture, and industrial wastewater were the main sources, following by medical wastewater. A non-carcinogenic risk assessment showed a low risk of EDCs in the groundwater of the study area, and the risk of drinking water was greater than that of skin exposure. EE2 had the highest non-carcinogenic risk and is suggested to be monitored in priority. |
