> Soldering does not generate metal vapor.

Seeing as a lot of solder is lead based i imagine this would be a huge safety concern if it did create lead vapor.

liquid lead has a vapor pressure (it was easy to google) but at what temperature or sustained duration it would be dangerous I don't have the background to assess. in terms of duration, heavy metal poisonings are cumulative over time.
