摘　　要：砷是自然界普遍存在的一种元素,因其具有毒性和"三致"效应已成为环境优先污染物之一。在查阅国内外大量文献资料的基础上,系统地阐述了水中砷的存在形式、毒性以及植物修复的概念、主要类型及其应用。从砷的超富集植物、水生植物和其他植物3个方面总结了不同植物对水体中砷的修复效率、影响因素及存在的缺陷。最后提出了水体中砷植物修复的主要研究方向,包括具有砷累积效应的水生植物的筛选、水中其他离子与植物生长和植物修复的相互作用以及与其他修复技术结合使用、砷超富集植物后处置与资源化利用等。Arsenic,a ubiquitous element in nature,has become one of priority environmental pollutants because of its toxicity and possible cause for carcinogenesis,teratogenesis and mutagenesis.On the basis of comprehensive review of domestic and international literature,the form and toxicity of arsenic in water,the concept of phytoremediation,the main types and their applications were systematically summarized in this paper.Then arsenic remediation efficiency,impact factors and defects of different plants were also described about As-hyperaccumulator,aquatic plants and other plants.The research directions of phytoremediation of arsenic in water were addressed in terms of the following aspects ： the finding of new As-hyperaccumulator of aquatic plants,relations between other ions in water and plant growth,combination with other remediation techniques,and disposition resource utilization of As-hyperaccumulator.
