A tiny amount of lead is a tiny bit poisonous. Magnitude matters.

And time. People with a bll level 76% above baseline will wonder in ten years why they have coordination problems and trouble thinking.

That's the point -- the worst of these products don't have levels above baseline!

With an average US blood lead level of about 1 microgram per deciliter, an increase of 76% is still less than 2 micrograms per deciliter which would have an imperceptible impact on any neurological function for an individual. People with even a tenfold (1000%) increase above baseline don't show perceptible coordination problems. Not writing to have an argument. Just see a lot of people who suffer from misperception of the impacts of tiny levels of contaminants, people lose sleep non-stop worry, sometimes even lose the equity in their "contaminated" house by walking away from their loan due to misinformation about risk.
