Research appearing in Archives of Environmental Health (May/June 1996; 51(3):214–220) suggests that there may be a connection between lead exposure and attention deficit disorders. In this study, lead levels were measured in hair samples from 277 first-grade students. These data were then correlated with behavior questionnaires completed by both parents and teachers.
The researchers found a clear relationship between higher lead levels and more negative behavioral ratings from teachers. In addition, lead levels tended to be higher in children who had been diagnosed with ADHD (Attention Deficit Hyperactivity Disorder) by a physician.
