Remodeling or attempting to remove these materials from a building can actually increase your risk of exposure. If you suspect these materials are in your home, seek professional help before remodeling. If you remodel, remember that careful cleanup is important to control exposure. Major sources of asbestos are deteriorating, damaged or disturbed insulation, fireproofing or acoustical materials, and floor tiles. You won't feel any immediate symptoms from excessive asbestos exposure, but there is the long-term risk of chest and abdominal cancers and lung disease.
Smokers are at higher risk of developing asbestos-induced lung cancer.
Young children to age six are especially at risk of unknowingly ingesting lead contaminated dust or paint chips. Small amounts of lead dust, ingested regularly, can cause delayed development, reading and learning problems, lowered IQ, hyperactivity and discipline problems. Larger doses can cause high blood pressure, anemia, and kidney and reproductive disorders in kids and adults. Lead accumulates in the body and its effects are irreversible. Formaldehyde is often used as a preservative or as an adhesive in pressed wood products, such as paneling and particleboard, and furniture.
