Why do manufacturers put lead in EVERYTHING?!?
What i'm most annoyed about (and why i asked this) is about lead in plumbing parts. If you go to a hardware store and get a metal plumbing fitting, it should say "Lead Free*" but then when you look at the details, it would say something like "The wetted surface of this product contains less than 0.25% of lead by weight". Basically you'd probably always find it saying "less than x%". But why can't it be ZERO? Maybe it's because their metals are always contaminated and they cannot make it 100% lead free?
Also, what about metal items like tools and keys? Why do they have to put lead in the metal? Does it make it easier to manufacture or something?
