抗生素抗性基因在水环境中的分布、传播扩散与去除研究进展

近年来，由于抗生素的滥用而造成的抗性基因污染问题越来越严重，抗性基因在环境中的危害也逐渐受到人们的重视.本文针对抗生素抗性基因这一“新型污染物”，综述了抗性基因在水体环境中的来源与污染情况；分析了抗性基因在环境中的传播途径与生态风险.此外，还重点讨论了污泥消化、人工湿地、消毒以及深度处理等不同水处理工艺对抗生素抗性基因的去除效果，指出不同去除技术的改进方向.并针对目前的污染状况，对今后的研究重点进行了展望.

Distribution,dissemination and removal of antibiotic resistant genes (ARGs) in the aquatic environment.

In recent years, the intensive use of antibiotics induces the development of antibiotic resistant genes (ARGs), which is an increasingly critical problem affecting human health, and the potential toxic effects of the ARGs have drawn great attention all over the world. This review gave an overview of the occurrence, potential sources, fate and ecological risks of ARGs in the environment. What’s more, the removal of ARGs by different treatment processes such as sludge digestion, constructed wetland, disinfection and advanced treatments were assessed, and the improving directions of different treatment processes were also pointed out. Additionally, the highlights in need for further research were proposed based on the current pollution status.
