Actually, 

Most wheel weights are now leadfree, that's why the cost went through
the
roof a couple of years ago.

And what about all those Dads taking their kids fishing with all those
lead
sinkers?  The Bait & Tackle shops will be raided next to remove lead
from
the shelves.

And the scuba divers will have to use rocks instead of lead ballast
weights.

And wheel balancing weights should be made lead-free too.

I remember back about 20 years ago, going to Gettysburg and watching
people try to find old bullets in the ground.  I find it interesting
that lead is stable enough to stay in topsoil for decades, yet seemingly
absorbed into the bloodstream very easily.  Yet, unless if I am
mistaken, there are little precautions for handling solid lead (based
upon what little I know of OSHA rules for soldering--we went through
that a couple of years ago and I don't remember anything bad being found
for us) required, outside of washing ones hands (and presumably not
nibbling on it).

It's all about lead dust, apparently.  I guess old lead based paint, as
it cracks (UV exposure? Last dregs of solvents outgassing, leaving it
more brittle?) is what causes the most exposure?

Yeah Richard, you wonder where peoples heads are at sometimes.

A lot of people forget where most all elevated blood lead levels in
children come from. It's from the paint in older homes built prior to
1978 when lead in paint was banned. Blood lead levels in children have
declined 89% since the ban in paint and the lead in gasoline. That being
said, there's still a lot of pre-1978 homes out there that people are
renovating and not being as careful as they should when they do that,
and a large percentage of children are still getting contaminated from
the paint even though it was banned over 30-years ago. Take care of the
paint in all the older structures and you will most likely eliminate all
elevated blood lead levels in children.
