Thallium is more toxic to humans than mercury, cadmium, lead, copper or zinc. Its chemical behavior resembles the heavy metal lead and the alkali metals (K, Rb, Cs). It occurs almost exclusively in natural waters as monovalent thallium (Tl+1). The solubility of thallous compounds (e.g., thallous hydroxide) is relatively high so that Tl+1 is readily transported through aqueous …
