Lead Poisoning in Children
Facts about lead exposure
Here are facts that can help you keep your children safe:
Lead poisoning is a totally preventable disease.
Lead exposure can harm young children and babies—even before they are born.
Even children who seem healthy can have high levels of lead in their bodies.
Children can get lead in their bodies by breathing or swallowing lead dust, or by eating soil or paint chips with lead in them.
Removing lead-based paint improperly can increase the danger to your family.
CDC estimates show that about half a million children between the ages of 1 and 5 living in the U.S. have an elevated level of lead in their blood.
Lead is more dangerous to children than adults because:
They often put their hands and other objects in their mouths that can have lead dust on them.
Their growing bodies absorb more lead.
Their brains and nervous systems are more sensitive to the damaging effects of lead.
Children between the ages of 1 and 3 who live in low-income housing built before 1978 are especially at risk. In early 2005, the Consumer Product Safety Commission announced a new policy addressing lead in children's metal jewelry. There have been cases where children who swallowed or repeatedly sucked on jewelry items containing lead developed high blood lead levels. Since 2004, the Commission has recalled over 150 million pieces of toy jewelry that were sold in vending machines and through other outlets.
Effects of lead in the body
Lead poisoning can affect just about every system in the body yet often produces no definitive symptoms. The following are some of the most common symptoms of lead poisoning:
Damage to the brain and nervous system
Behavior and learning problems, or slowed growth
Lead is also harmful to adults, and may cause:
Problems during pregnancy
Reproductive problems in both men and women
High blood pressure
Memory and concentration problems
Muscle and joint pain
High levels of lead may also cause seizures, coma, and death. The symptoms of lead poisoning may look like other conditions or medical problems. Always talk with your child's healthcare provider for a diagnosis.
Testing children for lead exposure
If you think your home has high levels of lead, get your children tested. A simple blood test can find high levels of lead, and is important for:
Children who are 6 months to 1 year old (6 months if you live in an older home that might have lead in the paint). If your child is older than 1 year, talk to your child's healthcare provider about whether he or she needs testing.
Family members whom you think might have high levels of lead.
Your child's healthcare provider can test your child's blood levels. The tests are inexpensive or, in some cases, free. Your child's healthcare provider will explain the test results. Treatment can range from changes in your diet to medicines or a hospital stay.
