poisoning had long-term implications for a child's attentiveness, behavior, and academic success. In 1979, Needleman began the first large-scale study of intelligence and behavior in children with no outward signs of lead poisoning. His research showed that lead exposure is associated with an increased risk for failure to graduate from high school and for reading disabilities. His research involved testing the concentration of lead in bones of 194 juveniles, between the ages of twelve and eighteen, who had been convicted in the Allegheny County Juvenile Court, and 146 students in regular high schools in Pittsburgh, Pennsylvania who did not have behavioral problems. In 1996, findings from the research, reporting on the physical and behavioral problems caused by leaded gasoline and lead paint while linking lead exposure to anti-social behavior, were published in the Journal of the American Medical Association. The study found that delinquent children were four times more likely to have elevated concentrations of lead in their bones. According to Needleman, "Lead is a brain poison that interferes with the ability to restrain impulses. It's a life experience which gets into biology and increases a child's risk for doing bad things." After extensive scientific review, Needleman's findings were instrumental in convincing the Centers for Disease Control (CDC) to issue guidelines for the diagnosis and management of lead poisoning in children, in goading the Environmental Protection Agency (EPA) to mandate the removal of lead from gasoline, and in inducing the Consumer Product Safety Commission to ban lead from interior paints. Needleman's research also helped cause the Department of Housing and Urban Development (HUD) to remove lead from thousands of housing units across the US. Needleman designed the first forward study of lead exposure during gestation, and showed that such exposure is associated with cognitive deficits later in life. His most recent research has shown that boys with high levels of lead concentrated in their bones are more likely to develop aggressive or delinquent behavior, such as bullying, vandalism and shoplifting. Raising Children Toxic Free In their book, Raising Children Toxic Free: How to Keep Your Child Safe from Lead, Asbestos, Pesticides, and Other Environmental Hazards (1996), Needleman and Philip J. Landrigan offer advice for parents and physicians on how to evaluate and minimize toxic exposure risks, which include lead, asbestos, pesticides, and other toxins. The authors also address practical means for ensuring community compliance with existing laws. Committee of Responsibility
