OK we all understand that the lead in lead solder poses very little  if any
danger to the hobby or small job shop builder.  We have all agreed that the
smoke  from the flux is not good to inhale, something the electronics
industry has been aware of for the last 25 to 30.
I have been aware if it and have taken active steps to eliminate the
problem for  the past 65 years.  Not because I am a "chrome dome" and did
months of research. but because I am an asthmatic and every time after an
enjoyable  evening spent building my latest "gee whiz" project, I would
spent the next three days to a week laid up.  My stepfather solved the
problem for under $15.00, He put a box fan  with a furnace filter on my
bench ... end of problem. No expensive fume hood needed.
I have used the same type of filter on every job where I have had to solder
or work around others soldering.
When I was employed as a quality control engineer by San Fernando electric
( At that time they produced Capacitor and Inductors) I specified the same
type of filter at every work station, with the result that lost production
due to illness dropped dramatically.
I suggest anyone worried about fumes from soldering with either lead or
lead free solder do the same, this is a simple, easy (and best of all)
cheap solution to the problem.
