Why do manufacturers put lead in EVERYTHING?!? Answered
Why is it that apparently almost everything contains lead? Almost all metal items appear to have lead... keys, tools, plumbing fittings... Also maybe in plastic.
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?
