Lead is a poison. Lead is harmful even in very small amounts, and it is most dangerous for young children.
Children with lead in their bodies usually do not look or act sick. A blood lead test is the only way to know if there is lead in your child’s body.
Protecting children from exposure to lead is important to lifelong good health. No amount of lead is considered safe. Even small amounts of lead can affect IQ, ability to pay attention, and academic achievement.
