Lead accumulates in the body and its effects are irreversible. If you live in an older home, your children may be at risk. All children up to age six should be tested for lead in their blood. Ask your public health department about lead testing programs for children. An estimated 57 million U.S. homes have at least some lead paint.
Older homes are at greater risk.
Prior to 1950, paint contained as much as 50 percent lead. Paint in good condition poses little risk. Paint that is peeling or on deteriorating surfaces is especially risky. Dust created from remodeling an older home can also be a source of lead. Their sensitivity is limited, though.
