lead is an element that was once used as a pigment and drying agent in paint. An elevated level of lead in the body can cause serious damage to the brain, nervous system, kidneys and red blood cells. The degree of harm is related to the amount of exposure and the age at which a person is exposed. The Federal government estimates that lead is present in about 75 percent of all private homes in the United States built before 1978.
