Quizplus · Accepted Answer

All of the options listed are sources of lead exposure, and each one can contribute to unsafe levels in children in different ways. Lead-based paint, particularly in older homes, can deteriorate and create lead dust, which children can ingest through normal hand-to-mouth behavior. Old water pipes made of lead can also leach lead into the water supply, resulting in ingestion through drinking water. Coal burning power plants and waste incinerators can release lead into the air, which can then settle onto soil and be ingested by children who play outside or eat produce grown in contaminated soil. Therefore, all of these options are potential sources of lead exposure for children.
