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.

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.
"Because of the relatively low temperatures in electronic soldering, fumes from these metal constituents themselves are not normally a concern"
Seems like a squirrely way of saying that it might be dangerous, but nobody has been inclined to check.
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.
Good suggestion. Sounds like you can add a new data point. How are your blood lead levels?
You can also use silver solder on copper.
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.
