You lost me as soon as you started talking about leaded gasoline. First, lead wasn’t taken out of gasoline to reduce lead exposure, it was taken out because the chemical additive fouls catalytic converters that clean the unburnt by products of combustion. As a person who hates driving behind old, pre-catalytic cars because they all stink I am glad of it. The relatively clean air around cities today compared to 40 years ago is at testament to the value of taking out lead and adding catalysts.
The reduction of environmental lead was a happy by-product of that change which has had it own beneficial results. Lead is toxic to the nervous system. I work in a lead acid battery factory and we take lead exposure very seriously, monitoring every employee, even those of us us in the offices, regularly. In children the effects are pronounced at much lower levels than adults so as a parent I am very happy that particulate exhaust and road dust are not a source of lead for my children.
I stopped reading at that point. If you are going to bring up something tangential to your point, at least get your facts straight so you don’t ruin your credibility up front.
I have my facts straight, how about you?
I will accept your apology although I think you have other issues with this and you were just trying to shut me up.
