Should I be concerned about lead in household dust and soils?
Lead can be found everywhere in our environment. Most of the lead in soils comes from particles falling out of the air and from rocks that contain lead. Lead-contaminated dust and soil can cling to skin, hair,
shoes, clothing and vehicles and can be carried indoors.
Dust and soil can be a source of lead exposure for small children because they are close to the ground and because of their hand to mouth activity. It is, however, very unlikely that a child could inhale or
consume an amount significant enough to result in elevated blood levels.
