Detailed explanation-1: -Exposure to lead can seriously harm a child’s health, including damage to the brain and nervous system, slowed growth and development, learning and behavior problems, and hearing and speech problems.
Detailed explanation-2: -Lead-based paint and lead-contaminated dust are the most common sources of lead poisoning. Paint containing lead was not banned in the United States until 1978. Homes built before 1978 have a good chance of having lead-based paint, which can chip, peel or flake.
