The author of this thread will not be convinced by any of this, but I offer it for the rest of you interested in knowing the caveats of going Pb-free in your soldering work:
It's All in the Whiskers

Electroplated Tin and Tin Whiskers in Lead Free Electronics
Aging Capacitors and Tin Whiskers (Low End Mac)
I could go on, but after reading this (you did read all those articles, right?) I am sure you get the point. There are also other issues of Pb-free solder being harder to work with, but I spare you those details.
Simply put, if you turn on a fan to blow fumes from your nose while you solder, and if you then wash your hands after your solder job is done, you need not worry one bit about poisoning yourself even in a tiny way. Indeed, if there is any thing to "worry" about, it would be the potential for electrical short failures induced by Pb-free solder "tin whiskers" some years down the line. It may take 10 years for that to occur, but without any Pb to prevent them, whiskers will emerge and grow to lengths longer than you may expect.
