We all appreciate keeping things safe, but the "lead is dangerous" thing has been intentionally exaggerated by the government and the media.
Lead was used in paint for a hundred years - nothing happened.
Why did this suddenly become high priority?
Because certain children ATE THE PAINT off the wall, and somehow the parents never noticed.
Do your children do that?
Inhaling dust is much, much less important - firing ranges begin to show statistics after years of continuous exposure to fresh air-born lead particles.

The official answer: "It can't be the parent's fault. We can't be racist and say that this only happens when the parents leave child rearing to the state, so we have to pretend that it happens to everyone".
