Air quality alarm for soldering

higheredundead:
Does anyone have a recommendation for an air quality alarm in a soldering environment to alert people if the existing filtration or ventilation is insufficient?

what's your definition of insufficient?

higheredundead:
Sure.  Let's go with OSHA standard: 50 micrograms of lead / cubic meter.  There could be other things to measure, too, like VOCs from the flux.  But we can start with lead.

Someone:
Lead in air, that's a spectrometer based method sampling the physical dust/particulates (on a filter pad).

how many kilo dollar-pounds do you have spare?

You don't really get lead fumes from soldering. VOCs and other nasties from the flux are the real danger.
The lead poisoning comes from getting it on your fingers and then ingesting it via nail biting or not washing hands before eating.
