No. But i remember a big fuss here to re-paint a lot of schools
to get rid of the lead paint. Seemed a prtty important issue. I
think lead paint is more dangerous as it flakes into tiny bits
with a high surface area that oxidise a great deal. I think the
contact with lead oxide is probably more dangerous than conact
with lead itself. Most metals are not biologically available in
their normal state, ie your body can't absorb them until they
are a oxide or sulphate or something. Like magnesium or iron
supplements, if you just ate iron dust or magnesium dust you
wouldn't absorb any. By the same logic, contact or even eating
lead probably wouldn't get into your blood unless it was lead
sulphide of something. I think that's why lead paint is the worst
type of lead for lead poisoning.

But how does that affect soldering? I often spend a few hours
a day with my face over a hot soldering iron, and who knows
more about the flux?

Isn't there a new lead-free solder? I have seen it in the EE
catalogues but never tried any.
