Antibiotics in water environment not only induce resistance genes and drug-resistant bacteria,but also endanger the safety of ecology and threaten human life and health.Fluoroquinolones and relevanted antibiotic resistance genes(ARGs)have been widely concerned by scholars at home and abroad.Levofloxacin(ⅠVFX),one of the most widely used fluoroquinolones,is widely detected in the environment due to its low metabolic rate in life and stable chemical structure.Therefore,it is urgent to get the concentration characteristic of LVFX in the water environment,and clarifies its harm to the ecological environment,compares and analyzes the removal effects of existing technologies.Based on the existing researches,the occurrence characteristics of LVFX in water environment was summarized,and the ecological risk of LVFX from two aspects of inducing ARGs and drug-resistant bacteria and threatening the ecological safety of water was expounded.The effect and research progress of LVFX removal by physical,chemical and biological methods were reviewed,and the advantages and disadvantages of these methods were analyzed.The purpose was to provide some references for efficient degrading LVFX and inhibiting the spread of ARGs.
