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