Lithium and water: reaction mechanisms, environmental impact and health effects

Seawater contains approximately 0.17 ppm lithium. Rivers generally contain only 3 ppb, whereas mineral water contains 0.05-1 mg lithium per liter. Large amounts of lithium were found in holy water from Karlsbad, Marienbad and Vichy. In solution it is only found as Li⁺ (aq).
