Almost all of the "smoke" is burning flux, not solder. Compared to
the amount of solder I use in my other hobby--brass musical
instrument repair--I suspect that the amount of airborne lead is
miniscule when a PCB is soldered.
Lead has quite a high (1740C) boiling point, so the vapor pressure of
lead at normal (217C) 63-37 Sn-Pb solder melting point is probably
very low.
However, I don't know about torching PCBs.
