Introduction Health Hazards Lead is highly toxic and affects virtually every system of the body. At high exposure levels, lead poisoning can cause coma, seizure, and death. While adults can also suffer from excessive lead exposures, the groups most at risk are fetuses, infants, and children under age of six years. At low levels lead’s neurotoxic effects have the greatest impact on children’s developing brains and nervous systems, causing reductions in IQ and attention span, reading and learning disabilities, hyperactivity, and behavioral problems.
