that's not necessarily true.

As a mechanical engineer I used to work in an electronics factory. there is still a lot of soldering done by hand. not to mention that the operators of the automated soldering machines. during this soldering process there is a considerable amount of fumes, even though you're using blowers and filters, that the workers are exposed to. Lead is known to be hazardous for long exposes. So I guess keeping the manufacture-workers safety is as important as the end user's one.
