The concentrations and distributions of five sulfonamide, three tetracycline, and two macrolide antibiotics in leachates from three landfill sites in northern Zhejiang Province, China, were determined by solid-phase extraction and ultra-high performance liquid chromatography mass spectrometry. Most of the antibiotics were detected in the leachate samples. The concentrations and distributions of the antibiotics in leachates of different ages were very different. The total sulfonamide, tetracycline, and macrolide concentrations in the leachates ranged from not detected to 1.57 × 103, not detected to 5.19 × 103, and 7.30 to 5.42 × 102 ng/L, respectively. The total concentrations of detectable antibiotics were higher in fresh leachates than aged and middle-aged leachates. Higher TC-group concentrations were found in the leachates than have been found in previously published studies of landfill leachates in China. The results improve our understanding of and ability to manage antibiotic residues in landfills.
采用固相萃取和超高效液相色谱-串联质谱法测定了中国浙江省北部 3 个垃圾填埋场渗滤液中 5 种磺胺类、3 种四环素类和 2 种大环内酯类抗生素的浓度和分布。大多数抗生素都在渗滤液样品中被检测到。不同年龄渗滤液中抗生素的浓度和分布差异很大。渗滤液中磺胺类、四环素类和大环内酯类抗生素的总浓度范围分别为未检出至 1.57×103ng/L、未检出至 5.19×103ng/L 和 7.30 至 5.42×102ng/L。新鲜渗滤液中可检测到的抗生素总浓度高于老化和中龄渗滤液。与中国先前报道的填埋场渗滤液中抗生素浓度相比，TC 组的浓度更高。该研究结果提高了我们对填埋场中抗生素残留的认识和管理能力。
