Prevent Children’s Exposure to Lead
The harmful effects of childhood lead exposure can be prevented. The key is to keep children from coming in contact with lead. Learn how to prevent children’s exposure to lead.
Lead in paint, soil, air, or water is invisible to the naked eye and has no smell. No safe blood lead level in children has been identified.
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
- Hearing and speech problems
There are many ways that parents can reduce children’s exposure to lead before they are harmed. Lead hazards in a child’s environment must be identified and controlled or removed safely.
Common Ways Children Can Come in Contact with Lead
Young children can be indirectly exposed to lead when they put objects containing lead dust, such as toys, trinkets, or their fingers, in their mouth as part of their normal development. Children may be exposed to lead through contact with paint chips and dust from lead paint in buildings and homes that may have landed on windowsills, the floor, toys, trinkets, or their fingers.
But their exposure is more common from swallowing house dust or soil contaminated by lead paint are the most common sources of lead exposure. Children can also be exposed to lead if they swallow chipped pieces of lead paint.
For example, old or worn lead paint peels and cracks, and tiny bits of lead dust settle on the dust and soil inside and around homes. This occurs on doors, windowsills, and wells. In addition, lead can be scattered when paint is disturbed during the following:

National Lead Poisoning Prevention Week: Lead-Free Kids for a Healthy Future
October 24-30, is National Lead Poisoning Prevention Week. This year’s theme is “Get the Facts, Get Your Home Tested and Get Your Child Tested.” Childhood lead poisoning is considered the most preventable environmental disease of young children. Approximately half a million U.S. children ages 1-5 have blood lead levels above the blood lead value at which CDC recommends public health actions be initiated.
National Lead Poisoning Prevention Week occurs every year during the last full week in October. Many states and communities offer free blood lead testing and hold education and awareness events. For more information about National Lead Poisoning Prevention Week activities in your area, please contact your state or local health department.
