They often play close to the floor and put things in their mouths. These natural behaviors make them more likely to be exposed if there are lead hazards around them. If lead is ingested, a young child's body tends to absorb lead into the blood more readily than an adult's body. Children who have diets that are low in iron and calcium tend to absorb more lead, so good nutrition is one vital element of lead poisoning prevention. Older homes, built before 1978, with peeling paint, pose the most risk for young children.
Lead poisoning can interfere with critical stages in a young child's development.
It can affect the development of a child's brain, bones, and internal organs. Children with lead poisoning can have learning disabilities, stunted growth, behavior problems, and other developmental difficulties. Children with lead poisoning often have no symptoms. The only way to tell is to have your child tested. A child can be poisoned and show no outward signs.
