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).
- matthewdgreen 3y agoThis 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.
- prepend 3y agoGood 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.
