Lead solder turns into lead oxide fumes which get absorbed into your blood through your lungs. https://warwick.ac.uk/services/healthsafetywellbeing/guidance/leadpolicy/soldering https://warwick.ac.uk/services/healthsafetywellbeing/guidanc... Plumbers don't do much soldering and use very little solder when they do. And lead solder has been banned in any pipe that carries drinking water since the 80s.

I think this is unlikely to happen at typical soldering temperatures. The lead vaporization point is over 3000 degrees F. https://ehs.mit.edu/wp-content/uploads/EHS-0167.pdf https://ehs.mit.edu/wp-content/uploads/EHS-0167.pdf

  You don't need to vaporize lead to form lead oxide. > https://ehs.mit.edu/wp-content/uploads/EHS-0167.pdf https://ehs.mit.edu/wp-content/uploads/EHS-0167.pdf The first page of this link you shared mentions lead oxide: > During the soldering process in the form of lead filler metals, lead oxide fumes are formed and excessive exposure to lead oxide fumes can result in lead poisoning.

> Plumbers don't do much soldering Today no. But in the past of course they did. Every house has 1/2" and 3/4" copper pipe with sweated solder joints. At least 10's of them in each house, if not 100 or more.

> lead oxide fumes which get absorbed into your blood through your lungs Ok, but if this happens wouldn't it be easy to run a study to show a correlation between working in solder-exposure occupations and accumulated blood lead level? There are millions of workers who would have been exposed in this way (e.g. me), not just a few folks working for big-bad-AT&T.
