Thallium - Wikipedia

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame ...

Thallium shows high levels (13–1100 μg/l) in deep groundwater within the Tl-mineralized area, decreasing with distance away from the mineralized area to background levels (<0.005 μg/l). The occurrence of Tl in the water system is dictated by Tl mineralization, water–rock interactions, and hydrogeological conditions.
