| 为了探究畜禽养殖场周边河流中雌激素类物质的污染特征，利用固相萃取-高效液相色谱-串联质谱（SPE-HPLC-MS/MS）方法，对上海市三个典型畜禽养殖场（猪场、鸡场、奶牛场）周边河流上下游地表水中雌激素的种类和含量进行测定。结果显示，天然雌激素E1（雌酮）、E2（雌二醇）和E3（雌三醇）在各个采样点均被检出，浓度范围分别为21.66~73.40、8.75~55.96、4.56~23.90 ng·L-1；人工合成雌激素EE2（乙炔基雌二醇）的检出率为99.44%，浓度范围是ND~19.42 ng·L-1，DES（己烯雌酚）的检出率为27.78%，浓度范围是ND~3.23 ng·L-1。采用EEQ（雌二醇当量）评价各水体中雌激素类物质的总体雌激素活性，结果显示，所有采样点EEQ的浓度范围为54.15~194.61 ng·L-1，在三个养殖场周边河流中，EE2对EEQ的贡献率均为最高。综合分析表明，三个典型畜禽场周边河流均受到不同程度的雌激素污染，且猪场和奶牛场周边河流中雌激素活性较高。典型猪场和典型奶牛场是E2的主要排放源，典型猪场是E1的主要排放源，而典型鸡场对周边河流产生的雌激素污染较小。 |

| In order to investigate the pollution characteristics of estrogenic substances in the rivers around livestock and poultry farms, The types and content of estrogen in the upstream and downstream surface water of river around three typical livestock and poultry farms(swine farm, chicken farm, dairy farms) in Shanghai were measured by solid phase extraction-high performance liquid chromatography-tandem mass spectrometry(SPE-HPLC-MS/MS). The results showed that the natural estrogens E1(Estrone), E2(17β-estradiol) and E3(Estriol) were detected in all sites. Concentrations ranged from 21.66 to 73.40 ng·L-1 for E1, from 8.75 to 55.96 ng·L-1 for E2, and from 4.56 to 23.90 ng·L-1 for E3. The rate of detection of EE2(17β-ethinylestradiol) was 99.44% and the concentrations ranged from not detected(ND) to 19.42 ng·L-1. The rate of detection of DES(Diethylstilbestrol) was 27.78% and the concentrations ranged from ND to 3.23 ng·L-1. The estrogenic activity was evaluated by using EEQ(estradiol equivalent quotient). The concentrations of EEQ ranged from 54.15 to 194.61 ng·L-1 in the studied rivers, of which the contribution rate of EE2 was the highest. In conclusion, our results showed that the rivers around the three typical livestock and poultry farms were subject to different levels of estrogen pollution, and the estrogen activity was higher in the rivers around the swine farm and dairy farm than chicken farm. The typical swine farm was a main source of E1 and E2, and the typical dairy farm was a main source of E2, while typical chicken farm produced less estrogenic contamination to the surrounding river. |
