摘要
锑作为一种具有潜在毒性和致癌性的元素越来越被人们所重视。由于矿物的开采和冶炼、化石燃料的燃烧等人为原因,大量的锑及其化合物进入到大气、水和土壤中,进而进入动植物及人体中。土壤中的锑迁移能力较弱,水中溶解态的锑迁移能力较强,而大气中的锑可以进行全球传播。植物对锑具有一定的富集能力;锑对动植物和人体均有毒副作用,职业暴露是人体锑中毒的主要原因。本文对锑在各环境介质中的存在,锑在环境介质间的迁移和转化,以及锑的生物效应的研究进展进行了概述。
As a potential toxic and cancerogcnic element, antimony has attracted more and more attention. Antimony and its compounds are present widely in atmosphere, water, soil, plants and animals as a result of human aetivities such as ore mining and smelting, burning fossil fuel, etc. Antimony can cause global environmental contamination by its transport with air, But it is difficult for antimony in soil because of intent adsorption by clay minerals. Dissolved antimony in water can be transported far and wide. Plants can enrich antimony. Research revealed that antimony has toxicity and side effect to plants, animals and hu- man beings. Occupation exposure was the main reason for human poisoning. This paper reviews the progress in research on the presence, transport and transformation of antimony in environmental media, and its bioeffect in the environment.
