Jeff, I remember reading a paper in Scientific American eons ago about the
affects of lead on human development, and they disputed the claim of the leaded
gasoline affect on young children. As I remember, the children showing affects
of lead poisoning also had ingested lead based paint chips from older buildings
where they lived.
At any rate, leaded gas is history in the US so there is no point in reviving
the debate.
As for the affects of leaded 'petrol' on catalytics, I owned a '79 VW Rabbit
that contained a section in the service manual on how to rended the car ready
for leaded fuel operation. The manual (The car is mercifully long gone, the
manual I still own) states that the lead plugs up the pores in the honeycomb
material in the converter.
Their solution? Remove the converter from the car, and using a large hammer
strike the converter repeatly to break up the honeycomb and then after shaking
the pieces out of the converter reinstalling the empty can.
A lot of the lead substitutes in the US state on the bottle 'Safe for Catalytic
Converters', but then again - Why would you run a lead substitute in a lead free
ready car?
