我国农田中砷污染现状及微生物修复机理的研究与展望

Status Quo of Arsenic Contamination in Chinese Farmlands and Remediation Mechanism of Microorganism

综述了我国农田中砷的累积现状,并简要阐述了目前砷污染土壤修复或调控的常用技术手段。在此基础上,重点介绍了微生物对环境中砷的作用能力以及相关机理的研究进展,并对今后研究的重点问题进行了展望。

The status quo of arsenic(As) accumulation in Chinese farmlands was reviewed.The currently adopted technologies and methods for remediating or regulating As contaminated farmlands were introduced briefly,and the advances in role and mechanism of microorganism in remediating As contaminated farmland were introduced emphasizely.Moreover,the key problems in future researches were prospected.
