I think we tend to have a lot less heavy metal poisoning in general than we did at different times in the past. It's only fairly recently that we realized how dangerous these metals are and started removing them from things like plumbing (that word comes from french/latin for lead), fuels, paints, even eating-wares. I think north america was using leaded gasoline up until the end of the 70s or so.

At least until the mid-late 80's. My roommate had a 71 Dodge Challenger and it was only around '89 or so that it became harder for him to find the leaded gas it needed in the NYC area.

And small engined airplanes still use leaded fuel.
