摘要

       抗生素及其抗性基因(ARGs)是环境中普遍存在的新兴污染物,其环境水平和分布特征等相关研究方兴未艾.本文在总结大量文献的基础上,着重阐述了我国环境多介质中抗生素及其ARGs分布特征的最新研究进展,介绍了抗生素的存在状况与环境水平,讨论了抗生素的浓度水平时空分布差异及其对水生环境的风险,进一步通过介绍ARGs在环境中的污染水平,评述了抗生素ARGs污染物分布特征、水平转移及相应的微生物群落结构变化,最后对这两类新兴污染物的环境分布研究进行了展望,并针对我国现状提出了今后的研究重点.

       Antibiotics and their resistance genes (ARGs) are emerging pollutants that are ubiquitous in the environment, and related research on their environmental levels and distribution characteristics is in the ascendant. Based on a large amount of literature, this article focuses on the antibiotics and their The latest research progress on the distribution characteristics of ARGs introduces the existence of antibiotics and environmental levels, discusses the differences in the spatial and temporal distribution of antibiotics concentration levels and their risks to the aquatic environment, and further reviews the pollution levels of ARGs in the environment and reviews the antibiotic ARGs The distribution characteristics of pollutants, horizontal transfer and corresponding changes in the structure of microbial communities.Finally, the research on the environmental distribution of these two types of emerging pollutants is prospected, and future research focuses are put forward based on the current situation in my country.
