The concentrations of 17 antibiotics in the surface water and groundwater of a typical river in the Huixian Wetland were measured, and the ecological and health risks of these antibiotics to surface water and groundwater were assessed. The three types of antibiotics measured included quinolones, tetracyclines, and sulphonamides. The results showed that the mean values of the three antibiotics in surface water were sulfonamides > quinolones > tetracyclines and in groundwater were sulfonamides > tetracyclines > quinolones, and the antibiotic residues were associated with aquaculture and livestock breeding in the wetland, which indicated that antibiotics had a very high rate of use in the Huixian Wetland. The results of the ecological risk evaluation showed that the potential risk of five antibiotics, namely ofloxacin, sulfadiazine, sulfamethoxazole, enrofloxacin, and doxycycline, was high. The results of the health risk evaluation indicated that most of the residual antibiotics were of a medium and low risk to humans.
测定了辉县湿地某典型河流地表水和地下水中17种抗生素的浓度，并评估了这些抗生素对地表水和地下水的生态及健康风险。所测的三类抗生素包括喹诺酮类、四环素类和磺胺类。结果表明，地表水中这三类抗生素的均值为磺胺类＞喹诺酮类＞四环素类，地下水中为磺胺类＞四环素类＞喹诺酮类，且抗生素残留与湿地中的水产养殖和家畜养殖有关，这表明辉县湿地抗生素的使用量非常高。生态风险评估结果显示，氧氟沙星、磺胺嘧啶、磺胺甲恶唑、恩诺沙星和强力霉素这五种抗生素的潜在风险较高。健康风险评估结果表明，大多数残留抗生素对人类的风险为中低等。
