摘要:
抗生素抗性基因是一种新型的环境污染物,为探究抗生素抗性基因在垃圾填埋场的污染特征,采集了上海老港垃圾填埋场中固体垃圾和渗滤液样品,采用实时荧光定量PCR技术检测了磺胺类抗生素抗性基因(sul1、sul2)、四环素类抗性基因(tetM、tetQ)、氨基糖苷类抗性基因(strB、aadA1)、大环内酯类抗生素抗性基因(ermB、mefA)、多重抗性基因(mexF)及I类整合子(intl1)等6类目标基因的丰度。结果显示,6类目标基因均在固体垃圾和渗滤液中检测到,丰度分别介于102-106、103-107 /ng ,且多重抗性基因、氨基糖苷类及磺胺类抗生素抗性基因检出丰度较高,说明垃圾填埋场是抗生素抗性基因潜在的储存库。在填埋场固体垃圾中,部分目标基因在1.5 m深处的丰度高于0.5 m深处;在渗滤液中,目标基因丰度和呈现老龄渗滤液大于新鲜渗滤液,部分目标基因在秋季的丰度大于春季,研究表明目标基因的丰度在垃圾填埋场中存在时空差异。(图8 表2 参41)
Abstract:
Antibiotic resistance genes (ARGs) are known as emerging environmental contaminants and pose a threat to public health. T o study the pollution characteristics of the ARGs in landfills, solid waste and leachate were collected from the Shanghai Laogang landfills. The Real-time Quantitative PCR was used to measure the abundance of 6 types target genes, including the sulfonamide antibiotic resistance genes (sul1, sul2), tetracycline resistance genes (tetM, tetQ), aminoglycoside resistance genes (strB, aadA1), macrolide antibiotic resistance genes (ermB, mefA), multiplex resistance gene (mexF) and class I integron gene ( intl1). The obtained results showed that 6 types of the target genes were obtained in both solid waste and leachate. The detection abundances of the target genes in solid waste and leachate were ranged from 102 to 106 /ng and 103 to 10 7 /ng, respectively. Moreover, the abundance of the multi-resistance genes, aminoglycosides, and sulfonamide antibiotic resistance genes were higher abundance than others . The abundances of some target genes in solid waste at the depth of 1.5 m were higher than that in the depth of 0.5 m, and the total quantity of target genes in the mature leachate was higher than that in the fresh leachate. Besides, the contribution of so me target genes in autumn was greater than that in spring. The results demonstrated that the municipal solid waste landfill was a potential reservoir of ARGs, what’s more, the abundance of target genes had spatial-temporal differences.
