Lead and asbestos were commonly used in home building until the late 1970s. 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 clean-up is important to control exposure. 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.
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 both 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 particle-board, and furniture. It has been linked to cancer.
