How are children primarily exposed to lead?

The primary way children are exposed to lead is through ingestion from various sources. This exposure often occurs when children encounter lead dust or lead-contaminated soil and then ingest it by putting their hands or objects in their mouths. Young children are particularly prone to lead exposure because they frequently explore their environments orally, which increases their risk of ingestion. Additionally, sources of lead ingestion can include lead-based paint that deteriorates and creates dust, lead-contaminated water from old plumbing, and even certain toys or jewelry that may contain lead.

Understanding that ingestion is the main route of exposure emphasizes the importance of public health measures aimed at reducing lead in homes, schools, and communities, as well as the necessity for screening children for lead exposure, particularly in high-risk environments.
