摘　　要：大环内酯类抗生素(MLs)作为一类新型有机污染物,广泛存在于水环境中,表现为“假持久性”,并且能够导致环境菌群抗药性产生.本文总结大量文献,分析了我国环境水体中MLs的存在状况与浓度水平,并对该类抗生素浓度水平的时空分布差异进行了讨论,同时总结了水环境中MLs光化学行为的最新研究进展,介绍了其光解动力学以及水环境因子对光解的影响,阐述了光降解路径与机理,最后对该类抗生素的环境存在特征及光化学转化研究进行了展望.Macrolide antibiotics(MLs),as a new type of organic pollutants,are existing widely in the environment and show pseudo-persistent,which could induce bacterial resistance in the environment.Based on a large number of peer-reviewed literatures,this review analyzed the occurrence and levels of MLs in the aquatic environment of China,as well as the seasonal and spatial distribution.Furthermore,the current research progress on the aqueous photochemical behavior of MLs was explored.The photodegradation kinetics and effects of aqueous environmental factors were discussed.The corresponding photodegradation pathways and mechanisms for typical MLs were summarized.Finally,the research prospects about the environmental occurrence and photochemical transformation of MLs were proposed.
