What is the most significant source of childhood lead exposure in a residence?

Answer: The scientific literature suggests that nationally lead-contaminated paint dust is the most significant source of childhood lead exposure.  Lead dust comes from deteriorating lead-based paint and lead-contaminated soil that gets tracked into your home. This dust may accumulate to unsafe levels. Common renovation activities like sanding, cutting, and demolition can also create hazardous lead dust. People, especially children, can swallow lead dust as they eat, play, and do other normal hand-to-mouth activities.
