摘要
锑(Sb)是一种典型的有毒有害重金属元素。由于自然过程和人为活动的影响,锑及其化合物广泛分布于大气、土壤、水体等表生环境中,锑的环境污染日益严重。Sb不是植物必需元素,但能够被植物体及农作物吸收。Sb对人体和动物体产生慢性毒性及潜在致癌性。本文主要通过分析Sb的主要矿物、锑及其化合物在表生环境中的分布与迁移特性,来阐述人体可能的锑暴露途径及由此产生的环境危害效应。
Antimony is a typical heavy element with high toxicity. Antimony and its compounds occur widely in the supergene environment （atmosphere, soil, water） induced by natural processes and human activities, and lead to increasing contamination of antimony. Antimony is not a necessary element for plants, but it can be uptaken by plants and crops. Antimony is chronically toxic and carcinogenic to human beings and animals. This paper briefly reviews the group of antimony minerals, the distribution and migration of antimony in supergene environment, and also documents the exposure way to antimony and the environmental risk caused by antimony.
