Lead poisoning is an illness resulting from exposure to lead. There is no known safe level of lead for humans, but children are at particular risk of harm from lead exposure. Young children are small, their brains are rapidly developing, and they are more likely to put their hands or contaminated objects in their mouths. Exposure to lead during pregnancy can also increase the risk to the unborn baby.
Exposure to lead can result in damage to the brain and nervous system, slow growth and development, learning and behavior problems, and hearing and speech problems.
