| 摘要: |
| 【目的】探明典型养殖区和重点养殖场对土壤和地下水抗生素、激素赋存种类及累积状况影响。【方法】采用高效液相色谱-三重四极杆质谱仪检测样品中的抗生素和激素，研究畜禽养殖对H县土壤和地下水中抗生素、激素赋存特征的影响。【结果】①磺胺类抗生素（SAs）在土壤中的检出率大于地下水。土壤、地下水中普遍检出激素，除醋酸甲地孕酮外，其他激素均有不同程度检出，且土壤中激素的检出率大于地下水；②土壤中检测出4种抗生素，分别为磺胺噻唑、磺胺间甲氧嘧啶、磺胺氯哒嗪、磺胺喹恶琳，其中磺胺间甲氧嘧啶和磺胺喹恶琳为主要检出抗生素，而在地下水中磺胺间甲氧嘧啶的累积质量浓度最高；③0~20 cm土层KTY04采样点激素质量分数高于60~80 cm土层土壤。而养殖区地下水中肾上腺皮质激素、睾酮、去甲睾酮为主要检出激素，其中JSY03采样点激素累积质量浓度最高达到325.0 ng/L。【结论】H县集中养殖区土壤中磺胺类抗生素检出值普遍较高，而在地下水中则较低。地下水中雌激素的检出值较高，而在土壤中处于中等水平。故畜禽养殖增加了养殖区周边土壤和地下水的风险，需要进一步确定磺胺类抗生素和雌激素的来源及其可能对生态系统造成的影响。 |

| Abstract: |
| 【Objective】The presence of undigested antibiotics used in livestock farming poses significant environmental concerns, as their disposal into water and soil can lead to contamination of the food chain. This paper presents the analysis of the distribution and concentration of these antibiotics in both soil and groundwater.【Method】Soil and groundwater samples were collected from an intensive livestock farming area in H county. Antibiotics and hormones in these samples were analysed using the high-performance liquid chromatography-triple quadrupole mass spectrometry.【Result】 ① On average, there was more sulfonamide (SAs) in soil than in groundwater. All but megestrone acetate hormones were found in soil and groundwater, although there were more in soil than in groundwater. ② Sulfamethiazole, sulfonamide intermethacil, sulfonamide and sulfoamine were found in soil. In the groundwater, the concentrations of sulfonamide intermethacil and sulfamquinoxine were higher than the concentration of other antibiotics. ③ The concentration of hormone KTY04 was higher in the 0-20 cm soil layer than in the 60-80 cm layer. In the studied area, adrenocorticoid, testosterone, and notestosterone were the dominant hormones, with their mass concentration reaching 325 ng/L.【Conclusion】Our study found higher mass concentrations of sulfonamides in soil than in groundwater, except estrogen whose concentration was high in groundwater and moderate in soil. The presence of antibiotics and hormones from livestock farming could lead to increased contamination of both soil and groundwater, particularly sulfonamides and estrogens. Continuous monitoring is needed to assess their potential impacts on ecosystems. |
