i was reading about the reasons why lead was taken out of petrol and one reason stated was increased lead levels was creating violence in some people.
why then, since unleaded became the norm the violence levels in britain have increased?
surely if lead was causing violence the violent crime rate would have been dropping for the last 20 years not increased to the mess we're in today.
save britain.........bring back leaded petrol!

Wikipedia is your friend:
Lead pollution from engine exhaust is dispersed into the air and into the vicinity of roads and easily inhaled. Lead is a toxic metal that accumulates and has subtle and insidious neurotoxic effects especially at low exposure levels, such as low IQ and antisocial behavior. It has particularly harmful effects on children. These concerns eventually led to the ban on TEL in automobile gasoline in many countries. Some neurologists have speculated that the lead phaseout may have caused average IQ levels to rise by several points in the United States (by reducing cumulative brain damage throughout the population, especially in the young).
As an aside, as part of their post-doctoral research, a friend of mine is looking into the effects of metals bioaccumulation in roadside species, specifically targeting metals used in catalytic convetors (platinum, palladium, rhodium etc.) as these are now shows levels of elevation in the environment. No idea on their toxicity mind.

Meh. When George Dubya Bush kicks the bucket, the average IQ rate in the US will rise by a few points. Edited by Pints on Saturday 4th September 08:26
