摘要
铊(Tl)是典型的剧毒重金属元素,在自然环境介质中含量很低。随着含Tl矿床、煤、石油等资源的开发利用,区域性Tl污染和中毒事件时有发生,对公众健康已经构成了严重威胁。本文就Tl污染来源、Tl的分布和运移、Tl对生态环境的危害、水土Tl污染防治等研究的进展进行了介绍,并初步提出了环境Tl污染研究方向。
Thallium is a typical heavy metal element of acute toxicity and quite low in concentration in the background environment. With the exploration and utilization of Tl-containing mineral deposits, coal, oil and so on, Tl regional pollution and poisoning accidents occurred from time to time, posing a serious threat to public health. An introduction was presented to advancements in the study on thallium pollution, origin, distribution and migration of thallium, its harm to the ecosystem, and countermeasures. A new direction for the research on Tl-pollution was also put forward.
