Ban On Leaded Petrol ‘Has Cut Crime Rates Around The World’

Banning lead in petrol is responsible for declining crime rates in Britain, the United States and other countries, startling new research suggests.

The astonishing conclusion threatens to overturn current thinking on crime and punishment. And it could undermine the reputations of leading politicians, including Rudy Giuliani, the frontrunning Republican presidential candidate, who is basing much of his appeal on the reduction of crime in New York City in the 1990s, when he served as mayor.

Published in the peer-reviewed journal, Environmental Research, the study reports a "very strong association" over more than 50 years between the exposure of young children to the toxic metal and crime rates 20 years later when they are young adults.

Evidence is growing that the banning of lead should take much of the credit for reducing crime rates. The toxic metal has long been known to damage brains and to lead to criminal and aggressive behaviour.

Research at Pittsburgh University found that adolescents arrested for crime in the city had lead levels four times higher than their law-abiding contemporaries, and a study of 3,000 possible causes of criminality in 1,000 young people by Fordham University, New York, found that high lead levels were the best predictor of delinquent and violent behaviour.

Britain – one of the last to get rid of the toxic metal – is one of the latest to enjoy a decline in crime.
