Gibt es einen Zusammenhang zwischen Bleivergiftungen und Kriminalität?

sehr interessanter Artikel von George Monbiot auf guardian.co.uk:

„The curve is much the same in all the countries these papers have studied. Lead was withdrawn first from paint and then from petrol at different times in different places (beginning in the 1970s in the US in the case of petrol, and the 1990s in many parts of Europe), yet despite these different times and different circumstances, the pattern is the same: violent crime peaks around 20 years after lead pollution peaks. The crime rates in big and small cities in the US, once wildly different, have now converged, also some 20 years after the phase-out.“

Yes, lead poisoning could really be a cause of violent crime
