土壤砷污染及其植物修复的研究进展与展望

Progress and Prospect on Arsenic Contamination of Soil and Its Phytoremediation

砷是一种广泛存在于自然界的类金属元素,砷及其化合物具有剧毒、致癌、致畸和致突变特性。土壤砷污染已成为严重的环境和公共健康问题之一,并日益受到人们的密切关注。本文介绍了土壤砷污染的概况、来源及其危害,同时探讨了土壤砷污染的植物修复的研究现状,文中最后对今后土壤砷污染植物修复研究方向进行了展望。

Arsenic（As） is a metalloid element widely distributed in the environment,and it has such chemical properties as high toxicity,carcinogenesis,teratogenesis and mutagenesis.Arsenic contamination of soils has become one of the serious environmental and public health issues,which has attracted more and more attention of the people.This paper reviews recent progress in research on the source and hazard of As which has made soil contaminated,and its phytoremediation.Finally,the phytoremediation technology for future research on arsenic is also prospected.
