环境中锑的分布、存在形态及毒性和生物有效性

Distribution, Speciation,Toxicity and Bioavailability of Antimony in the Environment

由于自然过程及人类活动的影响 ,锑及其化合物在环境中普遍存在 ,环境中锑的污染也日益严重。近年来 ,国外对锑污染的研究日益重视。锑不是植物必需的 ,但能够被植物根系吸收。已有证据表明锑对生物及人体产生毒性。本文主要对环境中锑的分布和存在形态 。

Antimony and its compounds are widely used in various manufacturing and semiconducting industries. It presents in the environment as a result of natural process and human activities. The contamination of antimony in the environment is increasingly severe. in recent years, interest in the relative research has grown in abroad. Antimony is non essential to plants, but can be readily taken up by roots from soils in soluble forms. Furthermore, research was carried out and proved the toxicity of some of its compounds to biota and human being. In this article, the authors mainly reviewed some researches on the distribution, speciation, toxicological behavior and availability of antimony to flora and biota in the soil and water.
