Childhood Lead Exposure

Young children often place their toys, fingers, and other objects in their mouths as part of their normal development. This hand-to-mouth activity may put them in contact with lead paint or dust.

New Findings on Blood Lead Levels in Children
A new report summarizes the findings of a review of clinical interpretation and management of blood lead levels <10 µg/dL conducted by CDC's Advisory Committee on Childhood Lead Poisoning Prevention. This report provides information to help clinicians understand BLLs <10 µg/dL, identifies gaps in knowledge concerning lead levels in this range, and outlines strategies to reduce childhood exposures to lead. In addition, this report summarizes scientific data relevant to counseling, blood lead screening, and lead exposure risk assessment. See "Interpreting and Managing Blood Lead Levels <10 µg/dL in Children and Reducing Childhood Exposures to Lead: Recommendations of CDC's Advisory Committee on Childhood Lead Poisoning Prevention"

The most common sources of lead exposure for children are chips and particles of old lead paint. Although children may be directly exposed to lead from paint by swallowing paint chips, they are more commonly exposed by swallowing house dust or soil contaminated by leaded paint. This happens because lead paint chips become ground into tiny bits that become part of the dust and soil in and around homes. This usually occurs when leaded paint becomes old or worn or is subject to constant rubbing (as on doors and windowsills and wells). In addition, lead can be scattered when paint is disturbed during destruction, remodeling, paint removal, or preparation of painted surfaces for repainting.

Lead, which is invisible to the naked eye and has no smell, may be found in other sources. These sources may be the exposure source for as many as 30% of lead-poisoned children in certain areas across the United States. They include

traditional home health remedies such as azarcon and greta, which are used for upset stomach or indigestion in the Hispanic community

imported candies

imported toys and toy jewelry

imported cosmetics

pottery and ceramics

drinking water contaminated by lead leaching from lead pipes, solder, brass fixtures, or valves and

consumer products, including tea kettles and vinyl miniblinds

Additionally, a variety of work and hobby activities and products expose adults to lead. This also can result in lead exposure for their families. Activities that are associated with lead exposure include indoor firing range use, home repairs and remodeling, and pottery making. "Take-home" exposures may result when people whose jobs expose them to lead wear their work clothes home or wash them with the family laundry. It also may result when they bring scrap or waste material home from work.

Protecting Children from Lead Exposure

Lead poisoning is entirely preventable. The key is stopping children from coming into contact with lead and treating children who have been poisoned by lead. The goal is to prevent lead exposure to children before they are harmed. There are many ways parents can reduce a child's exposure to lead. The key is stopping children from coming into contact with lead. Lead hazards in a child's environment must be identified and controlled or removed safely.

Concern about Your Child's Exposure

If you have any reason to suspect that your child has been exposed to lead contact your health care provider. Your child's health care provider can help you decide whether to perform a blood test to see if your child has an elevated blood lead level. A blood lead test is the only way you can tell if your child has an elevated lead level. Most children with elevated blood lead levels have no symptoms. The health care provider can recommend treatment if your child has been exposed to lead.
