Jan,

Having had a child with borderline health-risk lead levels, I can
understand the concern of all involved. One easy way to check for lead,
is by checking for iron...with a quick and easy finger-stick.
Iron and Lead bind at the same sites, so if your Lead is high, the Iron
is low...
Or so it has been explained to me.

I know inhaling lead-paint dust particles can increase Lead. But I do
not believe the fumes from soldering would be the same thing. It has
been 15+ years since I took chemistry. I think the fumes, are just
condensation from the liquefying process, though. After all, the Lead is
meant to re-solidify and hold things together. It's basic chemical
composition  is not changed.

Just some not very recently educated ramblings, but may give you some
ideas on where to start a serious investigation.
