Overview

Lead is a significant environmental threat to children, particularly those under the age of six.  Children are considered lead poisoned if their blood levels are greater than 10 micrograms per deciliter, although research suggests that blood lead levels between 5 - 10 micrograms per deciliter can also be harmful to children.  Despite this, the Centers for Disease Control and Prevention have not lowered the lead poisoning threshold.  Children can be exposed to lead in soil, water, air, and even some toys, but the most common source of lead poisoning is from lead based paint found in homes built prior to 1979 when lead additives were banned from use in residential paints.  Children with elevated blood lead levels may have neurological and physiological damage and subsequently experience lowered IQs, shortened attention spans, and learning and behavioral problems.  Because children who are lead poisoned often do not exhibit any symptoms, a blood test is the only reliable way of knowing whether or not a child has been exposed to hazardous amounts of lead.  Low-income children are at an increased risk of lead poisoning because of the older housing stock in which they often reside. Those who receive Medicaid are entitled to receive lead screenings at regular intervals, but frequently do not.
