Jul 18, 2021 Thallium, a chemical element with the symbol TI, has an atomic number 81 on the periodic table. Thallium sulfate was once used as an ant and rat poison.[1][2][3] The occupational limit for thallium exposure is 0.1 mg/m^3 to the skin for eight hours a day. Levels of 15 mg/m^3 are considered immediately dangerous to one's health.
