Thallium salts have also been used in the treatment of skin diseases, but the high rate of toxicity compared to the therapeutic benefits limited its medicinal applications. Manganese nodules, found on the ocean floor, contain thallium. However, it is usually recovered from flue-dust residues from zinc and lead smelters and as a by-product of cadmium production. How People Are Exposed to Thallium. DESCRIPTION: Thallium was discovered by Sir William Crookes in 1861. Thallium isn't found freely in nature, and it has kind of a bad reputation as a toxic element. Thallium, the substance which has poisoned ex-KGB agent Alexander Litvinenko in London, is a highly-toxic heavy metal. Consequently, stomachaches will appear and the nervous system will be damaged. In the past, thallium was used in rodent killers and hair removal products. The Government is also proposing, however, that thallium and its compounds may be entering the environment at levels that are harmful to the environment. Presently our sources of thallium rely on naturally occurring deposits. Thallium-bearing minerals include crooksite, lorandite and thalcusite which occur as minute inclusions in sphalerite. Small amounts of thallium are used to make certain medical agents and electronics. Since 1984, the United States has not produced it. Thallium is a member of the aluminum family, Group 13 (IIIA) on the periodic table. Thallium is chiefly obtained as a by-product of zinc and lead processing.
