Abstract:

Arsenic hazard is severe serious to environment and human health. In recent years, arsenic is paid high concern as a toxic metallic element. This paper summarized the latest research results at home and abroad, deemed that there existed an obvious tendency of arsenic accumulation in arable land in China. The paper also analyzed the natural and anthropogenic sources of arsenic. Meanwhile, this paper systemetically introduced the related control measures adopted at present including the physics, chemistry, biology, and agronomy methods, from the angle of removing arsenic from arable land and reducing its effectiveness. Furthermore, this paper prospected the future research direction and hotspots.

Key words: soil, arsenic, regulate and control, microorganism, chemistry, agronomy

摘要：

砷是一种对环境乃至人体健康危害非常严重且近年来备受关注的有毒类金属元素。通过总结近年国内外相关研究结果，认为我国农田中存在较明显的砷累积趋势，并对农田中砷的自然和人为来源进行了分析。同时，从农田中砷的移除和降低砷有效性的角度，就目前采用的物理、化学、生物和农艺等相关调控措施进行了系统介绍，并对今后的相关研究方向及热点进行了展望。
