How do young children primarily ingest lead-based paint?

• A. Hand-to-mouth activity
• B. Inhalation only
• C. Skin contact
• D. Eating spoiled food

Answer: (A)

Young children mainly ingest lead-based paint through hand-to-mouth activity. At this age, kids frequently put their hands, toys, and other objects into their mouths, so dust or paint chips containing lead on floors, window sills, and surfaces can be transferred to the mouth. This makes ingestion the primary exposure route for lead from paint in young children. Inhalation of lead-containing dust can contribute as well, but it is generally a secondary route compared to mouthing. Skin contact with lead isn’t a significant ingestion pathway because intact skin doesn’t absorb much lead. Eating spoiled food isn’t related to how lead from paint enters the body.
