Known for decades that working around lead smelters and places where lead is vaporized (like indoor ranges) does this. Almost no electronic device sold in the western world contains more than a milligram or two of lead- and hasn't in almost 20 years (thanks to RoHS).

So what's the angle here, and why do they call out lead so often when there are so many other heavy metals in use?

Oh wait... ammunition depends on lead. Reminds me of when Obongo's EPA shut down the last primary lead smelter in the US and ammo immediately got constricted and expensive.

So do cheap, long-lived lead-acid batteries. What's the alternative? Chinese lithium batteries that have a tendency to explode in flames when ruptured and have a much more limited life span.
