摘　　要：铊是一种典型的分散、剧毒元素,相较于Cd、Cu、Pb、Hg等常见的重金属元素,铊表现出更高的毒性,但由于其在地壳中丰度低,现有研究及标准制定过程中对其关注较少。伴随着含铊矿石的开采与利用,大量铊被释放到地表环境中,造成严重的土壤和水体铊污染,铊污染防治工作形势严峻。通过整理近年来国内外研究报道和相关规范标准,针对土壤中铊的评价标准、污染现状、迁移转化行为、生态毒性和修复技术等进行了综述,并基于现阶段研究存在的不足,提出了今后的研究方向。Thallium is a typical dispersed and highly toxic element.Compared with common heavy metal ele-ments,such as Cd,Cu,Pb,and Hg,thallium shows higher toxicity.However,due to its low abundance in the crust,there is relatively little attention paid to thallium in the research and related standard.With the exploitation and utilization of thallium-bearing ores,a large amount of thallium is released into the surface environment,causing serious thallium pollution.The thallium pollution prevention and control work is grim.This paper summarizes the evaluation criteria,pollution situation,migration,transformation beha-vior,toxicity and remediation techniques of thallium in soil by reviewing the domestic and foreign research reports and related standards in recent years.Based on the shortcomings of the present research,this paper puts forward some suggestions for the future research.
