Individual exposures vary; I was speaking more on the epidemiological usage of 'us'. but the vast majority of people were exposed to decades of lead to some degree or another, and the 'safe' dose is very very low.

Folks in the suburbs weren't living in the big cities, but they certainly were driving everywhere. And pollution controls like catalytic converters, etc were aimed at smog-producing emissions like nitrogen oxides; tetra-ethyl lead got mostly burned to lead oxides and went out the tailpipe as fine particulates. If you lived your whole life out in the boonies, you definitely got a lower dose, but if you lived around a gasoline powered vehicle. you got some.

The sad and infuriating thing was this was known from the beginning. https://www.smithsonianmag.com/smart...ted-180961368/

Ethanol works better than TEL to raise octane.
