Recently,
studies about effects of metals and heavy metal compounds -which are
pollutants- on all biological systems have become more important. 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. Besides paints, ammunitions, radioprotective shields, jewellery,
fish poles and cable coating are other usage areas. 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. Half life of lead in bones is approximately
20-30 years. It has been proved that lead accumulated in body causes several
neurological insults, lower academic success, behavioral disorders, hearing
disorders and mental deficiency. And also Lead exposure has caused birth weight,
reduction of the gestation period, the short stature in children furthermore
delayed sexual maturation in girls.

In this
compilation exposure of lead which is an important toxic substance in pollution
and effects on infants and children health will be mentioned.
