Water pollution containing lead compounds derived from lead ores in the mining industry was first mentioned by architect Vitruvius, in 20 B.C., when he gave out a warning of its health effects. In Rome lead was often released as a by-product of silver mining. Lead white, an alkalic lead carbonate (2PbCO 3. Pb(OH) 2), is a white pigment. It is no longer applied because of its extreme toxicity,Air Quality - Lead - Environment,The natural concentration of lead in the air is less than 0.1 microgram per cubic metre.
