Can anybody point to legitimate data regarding the risks associated with electronics soldering? I'm not talking about:
1) Claims made by companies selling solder fume extractors.
2) Claims full of weasel words such as "may" and "potentially".
3) Claims made without reference to actual data.
4) Claims based on deliberately exposing animals to huge amounts of fumes and then trying to infer something about the risks for humans receiving much lower levels of exposure.
5) Reports of harm resulting from eating solder. Eating solder is something different from soldering.
6) Personal anecdotes.
7) Appeals to "common sense" or regulations or "everyone knows that".
Useful data could be, for example, evidence that people who work on the assembly line soldering all day (with/without fume extraction) consistently have higher rates of some disease compared to groups of people who don't solder.
