Tetraethyl Lead and Crime

Mother Jones political blogger Kevin Drum discusses what may be the hidden villain behind rampant crime, lower IQs, and even the ADHD epidemic: tetraethyl lead. In his article "Criminal Element," he postulates that lead in gasoline may account for 90 percent of the fluctuations in violent crime over the last 50 years, and he shows the upside to investing in lead abatement. The article appears in the January/February issue of the magazine.
