再生水利用对环境中抗生素抗性基因影响的研究进展

基于再生水利用对抗生素抗性基因的迁移转化规律及机制研究的大量文献,对当前再生水利用对环境中抗生素抗性基因影响的研究进行了较为系统的总结与分析,并对再生水利用过程中影响抗生素抗性基因传播扩散的再生水系统、环境污染物和环境因子等因素进行了简要分析。同时,在分析目前研究进展的基础上展望了今后的研究重点:灌溉技术、灌溉制度对土壤和作物体内抗生素抗性基因的影响;长期利用再生水对地下水中微生物群落结构和抗生素抗性基因的影响;抗生素抗性基因在再生水-土壤-作物系统中的迁移转化。

Occurrence of Antibiotic Resistance Genes in Environment with the Application of Reclaimed Water:A Review

The fate of heavy metal,antibiotics,bacterial community and so on in soil with reclaimed water irriga-tion had been investigated,however,the effect of reclaimed water irrigation on the fate of antibiotics resistance genes (ARGs)was remain unknown.Through the literature review,the occurrence of ARGs in environment with the application of reclaimed water and the factors that affecting the behavior of ARGs during the process of re-claimed water irrigation were illustrated.To better interpret the fate of ARGs,future research should focus on:the occurrence of ARGs in soil and crop with various irrigation technique and irrigation system,long-time monitor-ing the fate of ARGs and bacterial community in groundwater under reuse of reclaimed water,and the transforma-tion of ARGs in reclaimed water-soil-crop system.
