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. 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.
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.
