Lead, a naturally occurring metal found in the earth's crust, is toxic to humans. Until 1978, it was freely used in homes as a component of some paint, faucets, solder, pipe and pipe fittings, and roof flashing. Houses built before 1960 are very likely to contain materials with lead. Homes built between 1960 and 1978 may or may not contain lead paint or plumbing. Homes built after 1978 should not contain lead materials unless dated products were used in the construction.
Lead is a hazard when ingested or inhaled. Drinking water that has traveled through lead in pipes, breathing dust from sanding lead-based paint—these activities poison the body. Even though the amounts taken in may be minute, this toxin builds up over time, causing serious neurological conditions. Children younger than six years old are particularly vulnerable (this is why the hazards of toys containing lead paint have been in the headlines). If you have young children, it's wise to test for lead in your home. If you have concerns about lead in your plumbing, test your drinking water. Lead paint is a hazard when it is exposed as the surface coat, if it is deteriorating, or if you sand or scrape it when remodeling. |
