Seems to still be pretty pointless considering that roads and parking lots and garages are all to be avoided if you want to avoid exposure… just stay away from any of those

It's great for things you wouldn't expect. Like mercury in fish, or lead and BPA in plastic.

I have yet to see any of that in practice. Guessing no one is enforcing it.

There was a push to crack down on over labeling, but manufacturers have pushed back quite a bit.
