In Arumville, among those young children with elevated levels of lead in their blood, few live in houses containing lead-based paint, but many live in areas where vehicular traffic is heavy
These children' s elevated blood-lead levels probably result from lead added to gasoline, since, although gasoline sold in and around Arumville has been lead-free since 1990, lead from vehicle exhaust remains in the soil for many years
If improperly carried out, the removal of lead-based paint from older houses can significantly increase the risk that children living in such houses will ingest lead dust.
