Lead is a hidden and permanent toxic metal. Because of its free machining characteristic, lead has an extensive usage area. The major part of its usage area is batteries.

Increasing population, rapid industrialization and urbanization has increased lead exposure and remarked its toxic effects on environment and human health. The most sensitive groups about lead exposure are infants, pregnants and workers who work for jobs that have extreme lead contact. While 40 mg/dl of Pb level in blood for adults requires treatment; this level is lower for children and pregnants. However toxic effects of lead depend on individual’s age, dosage of exposure and frequency; personal genetic differences are also important. In societies due to lead’s cognitive and behavioral effects, mostly children’s exposure is overstressed. 75% of lead is accumulated in bones, the rest of it is dangerously spread to soft tissues.
