Lead Levels and ADHD
Research appearing in Archives of Environmental Health (May/June, 1996;51(3):214-220) indicates that there may be a connection between lead leavels and ADD. Lead was measured in hair samples from 277 first graders. The data was correlated with questionnaires from parents and teachers. The researchers found a relationship between lead levels and negative ratings from teachers. They also found that lead levels tended to be high in students with doctor-diagnosed ADHD (Attention Deficit Hyperactivity Disorder).
