摘　　要：富营养化导致的蓝藻水华暴发不仅破坏生态环境,而且影响人类正常生活,因而近年来受到了广泛关注。有效控制蓝藻水华的生长是当前亟待解决的重要问题之一,投加杀藻剂是及时控制蓝藻水华的有效方法,目前已有较多研究关注杀藻剂的发展,但鲜有研究从实际应用的角度出发全面总结常见杀藻剂的研究现状。针对铜绿微囊藻这一典型蓝藻,重点介绍了近年来备受关注的几种杀藻剂,主要从杀藻效果、作用机理、对微囊藻毒素的影响以及实际应用潜力等方面进行了综述,以期为实际水体中控制蓝藻水华的杀藻剂选择提供指导。此外,指出了应关注化感物质超过环境本底水平时的风险和非化感物质长期作用的风险,并综合考虑使用效果和安全性,提出了生态友好的杀藻剂应具备的特点以及采用缓释和联用等策略改善现有杀藻剂缺陷的思路。The cyanobacteria blooms caused by eutrophication has received widespread attention in recent years,which endanger the environment,destroy ecological environment and affect the normal life of human beings.The control of cyanobacterial blooms is one of the important issues to be solved at present.The chemical method of adding algaecide is very effective for timely control of cyanobacteria blooms.However,few studies have comprehensively summarized the practical application of common algaecides despite the attention given to their development.Some algaecides which have received much attention in recent years for the typical species of cyanobacteria were focused on.For Microcystis aeruginosa,a typical cyanobacteria,the algicidal effect,the working mechanism,the effect on the microcystin(MC),and the practical applications of these algaecides were reviewed.It was hoped to provide guidance for the selection of algaecides.Moreover,the potential risks of excessive background concentrations of allelopathic substances and long-term use of nonallelopathic substances have also been noted.Considering the algicidal effect and safety,the characteristics of the ecologically friendly algaecide were summarized.Additionally,strategies such as slow release and combined use were proposed to address current algaecide limitations.
