摘要

探讨砷在水生植物无根萍中的微区分布及与其它元素分布的相互关系

将有助深入认识水生植物对砷的富集和解毒机制

为用水生植物对含砷水体进行生物修复奠定理论基础。本研究用同步辐射X射线荧光成像技术（microfocused synchrotronbased X-ray fluorescence

μXRF）分析无根萍Wolffia globosa中As及其它7种元素的分布特点。结果表明As与K、Mn和Zn的分布规律类似

与Cu、Fe、Ni和Ca的分布无明显相似性。

Abstract

Distribution of arsenic and the relationship with other elements in aquatic macrophytes Wolffia globosa is helpful in understanding mechanisms of arsenic accumulation and detoxification

which will be important for arsenic phytofiltration in contaminated water by aquatic macrophytes.In this paper

we study the distribution features of As and seven more elements in rootless duckweed Wolffia globosa by means of μXRF.The results indicated that the distribution of As was similar to that of K

Mn and Zn while differs from that of Cu

Ni and Ca.
