Indicator Profile of Childhood Lead Testing Coverage

Why Is This Important?

Lead is a heavy metal that has been widely used in industrial processes and consumer products. When absorbed into the human body, lead can have damaging effects on the brain and nervous system, kidneys, and blood cells. Lead exposure is particularly hazardous for pre-school children because their brains and nervous systems are still rapidly developing. Serious potential effects of lead exposure on the nervous system include: learning disabilities, hyperactivity, hearing loss and mental retardation.

The primary method for lead to enter the body is through eating or breathing lead-containing substances. Major sources of lead exposure to children are: peeling or deteriorated leaded paint; lead-contaminated dust created by renovation or removal of lead-containing paint; and lead contamination brought home by adults who work in an occupation that involves lead, or who engage in a hobby where lead is used.
