Not really [0], leaded gas was completely banned in the US in 1996 but really hadn’t been used since the early 80s and had start the phase out in 1996. So you’d probably need to look at people in their 50s who really had an impact of lead from auto fuel.

Where "completely" in this case implies "for road-going vehicles". General aviation (largely small, piston-engine planes) still overwhelmingly run on 100 octane low-lead (100LL).

  This is a very big deal if you spend time around small aircraft (hangar floors in particular sometimes have terrifyingly high lead levels.) But if you’re not spending time close to aircraft, the amount of lead you’ll be exposed to is negligible - at least compared to auto emissions, which were ubiquitous and extremely concentrated in residential neighborhoods. Unfortunately the lead remains in the soil, so there’s still exposure to it today.

  Good point. I meant “completely” for consumer vehicles in the US. That’s what was pumping out all that lead into the air in the US. The other uses were much smaller.

Leaded gas is still not banned today. I have a car which only consumes leaded race gas and while it is surely expensive it is definitely not illegal.

  Many smaller, older aircraft use leaded fuel as well.

    Basically most piston engine aircraft use Avgas 100LL (low lead solution). So the majority of the air traffic found at a typical municipal airport. Fortunately this is being phased out by the FAA in favor of unleaded.

  On road use is banned. Also, the cost per gallon of leaded gas is at least $10/gallon now, which is a pretty large incentive enough for people not to use it :)

> really hadn’t been used since the early 80s I had summer jobs at gas stations in the early 90s and maybe 10% of the fuel sold was leaded.
