What are the sources of childhood lead poisoning?
The most common source of lead poisoning for children in the U.S. is lead from house paint. As lead paint ages, it can deteriorate and mix with dust in the home. On the outside of the home, lead paint can deteriorate, fall to the ground and mix with soil near the house. Lead can be found in paint in housing built before 1978. Soil near old, metal smelters can have high levels of lead. Soil near highways and heavily traveled roads can also have high lead levels.
