中文摘要：

稻米重金属超标已成为我国当今社会关注的焦点。引起稻米重金属超标的因素很多,随着研究的深入,近年来大气沉降与稻米重金属累积的关系也逐渐得到了关注。本文就大气沉降的概念、大气沉降重金属来源及其危害作了简要的概述,并重点综述了大气沉降与作物重金属累积之间的关系,分析了有色金属矿区稻米重金属超标与大气沉降之间的关联,并对该领域的研究前景进行展望。

英文摘要：

The high level of heavy metal in rice has became the focus of our society. There are many factors that bring about high accumulation of heavy metal in rice. The research on the relationship between atmospheric deposition and the accumulation of heavy metals in rice has gradually called attention. A brief summary was made of the concept, sources and hazard of atmospheric dustfall deposition, and the relationships between atmospheric deposition and accumulation of heavy metals in crops were reviewed, based on which relation between the high heavy metal content in rice and the atmospheric dustfall in the non-ferrous metal mining area was analyzed. Future prospects for research in this field were also made.
