This argument is fallacious. It is not 100C in my house, but water is evaporating and water vapor is in the air; the air is 40% saturated with water vapor.
The vapor pressure of lead is pretty low at typical soldering temperatures, though.
- hammock 3y agoNotwithstanding the vapor pressure, there are other ways non-boiling lead can make it into the air. Lead-core candlewicks are well studied and put tons of lead into the air as the candle burns at 500C or less
