You are correct, but since some may read that and assume that all aviation fuel is leaded, I wanted to add more info.
Most people don't know that "airplane fuel" and "jet fuel" are different. Jet fuel is not leaded. The fuel used by small, piston-driven prop engines is. Because small piston aircraft still use leaded fuel, aviation is still the largest source of airborne lead emissions. The FAA is working to phase it out by 2030.
You know what's funny? One of the "quirky" things about the Fallout Universe is how everything is radioactive because all their tech is based on fission/fusion right? It's meant to be funny like haha yeah our pollution is bad but atleast we're not poisoning ourselves with everything we do. Yet if you sub out "radioactive" for "heavy metal contamination" and "microplastics" etc that's basically 100% accurate to real life america.
Iirc locations downwind or under approach/depart flight lanes of small airports deal with an exposure risk fairly above baseline. I feel like I remember reading then that it ties into modern redlining where there are more minority populations in those areas due to cost of housing and the generational impacts of lead exposure.
So it’s the Cessnas spraying us with chemicals then? I thought it was the ones with the clearly harmless contrails but dang.
