铊是一种稀有分散元素.近年来随着含铊矿产资源的开发,使较多的铊元素进入环境并在环境当中富集.铊是一种高毒性的物质,通过食物链进入生物圈,对生物体和人体健康产生毒害作用、由于铊对环境造成的影响具有明显的滞后作用,其潜在的危害和威胁远比近期影响严重得多,所以它将成为未来环境中的“化学定时炸弹”.
Thallium is a rare but widely dispersed element. In recent years, with the exploitation of mineral resource containing thallium, a large number of element thallium flowes into and concentrates in the environment. Thallium is highly toxic and can easily flow into the biosphere through food chain. Consequently, it has terrible deleterious to the living organisms and the human body health. Because of the influence of thallium on the environment has the obvious lag, its latent harm and threat is much more serious than the performance influence, therefore it will become "chemistry-timing-bomb" in the future environment.
