The concentration and distribution characteristics of 27 antibiotics, including 8 sulfonamides, 9 quinolones, 4 tetracyclines, 4 macrolides, and 2 nitroimidazoles, in the surface water, groundwater, and wastewater of the Jinjiang River basin in Jiangxi province were determined using solid-phase extraction combined with ultra-performance liquid chromatography-tandem triple quadrupole mass spectrometry. The results showed that there was antibiotic pollution in the waters of the Jinjiang River basin. A total of 20 antibiotics were detected in the surface water, with a concentration range of 32.3-280 ng·L. There were 15 types of antibiotics detected in the groundwater, and the concentration range was 28.4-55.8 ng·L. Twenty-one types of antibiotics were detected in the wastewater, with a concentration range of 231-8.71×10 ng·L. A comparison with the concentrations of eight common antibiotics in rivers and lakes in China and abroad showed that the pollution level in the Jinjiang River basin was at a medium level. By comparing the concentrations of sulfamethoxazole in groundwater from domestic and international samples, the groundwater pollution in the Jinjiang River basin was clearly in the middle and lower range. A comparison of the concentrations of the three antibiotics in the aquaculture wastewater from domestic and abroad samples indicated that the pollution level of sulfadiazine in the aquaculture wastewater from the Jinjiang River basin was relatively high. The ecological risk assessment results showed that there were nine medium- and high-risk antibiotics, which were clarithromycin, erythromycin, ciprofloxacin, sulfathiazole, roxithromycin, tetracycline, ofloxacin, enrofloxacin, and sulfamethoxazole; the rest were low-risk or no-risk antibiotics.
采用固相萃取结合超高效液相色谱 - 串联三重四极杆质谱法，测定了江西省锦江河流域地表水、地下水和废水中27种抗生素的浓度及分布特征，其中包括8种磺胺类、9种喹诺酮类、4种四环素类、4种大环内酯类和2种硝基咪唑类。结果表明，锦江河域水体存在抗生素污染。地表水中共检测出20种抗生素，浓度范围为32.3 - 280 ng·L。地下水中检测出15种抗生素，浓度范围为28.4 - 55.8 ng·L。废水中检测出21种抗生素，浓度范围为231 - 8.71×10 ng·L。与国内外河流湖泊中8种常见抗生素的浓度比较表明，锦江河域的污染水平处于中等水平。通过比较国内外样本中地下水中磺胺甲恶唑的浓度，锦江河域的地下水污染明显处于中低范围。比较国内外样本中养殖废水中三种抗生素的浓度表明，锦江河域养殖废水中磺胺嘧啶的污染水平相对较高。生态风险评估结果表明，有9种抗生素具有中高风险，分别为克拉霉素、红霉素、环丙沙星、磺胺噻唑、罗红霉素、四环素、氧氟沙星、恩诺沙星和磺胺甲恶唑；其余为低风险或无风险抗生素。
