Lead Exposure Leads to Criminal Behaviour???

There has been a saying recently that the children who are exposed to lead early in their life are arrested later due to some criminal activities. Childhood lead exposure has been linked with anti-social behavior, lower IQ, attention deficits, hyperactivity and weak executive control functions, all of which are risk factors for future delinquent behavior (attention-deficit hyperactivity disorder, in particular, is a risk factor for adult criminal behavior). Studies have also related sales of leaded gasoline or high atmospheric lead levels with criminal behavior. Arrest rates were higher as blood lead concentrations went up. The association between high blood lead levels and violent crimes was even stronger. Any 5 micrograms per deciliter elevation in blood lead levels increased the rate of arrest for violent offenses by more than 25 percent. So it is better to avoid lead during early days.
