Don’t aircraft still use leaded fuel to this day?

Only some small piston based aircraft engines. Commercial aviation doesn't use lead. It's not great, but it's not a particularly significant amount.

Jet aircraft use jet fuel(more refined Kerosene).

So uh, there was some studying being done at my local university about mapping health issues for residents living closer to airports and.... It ain't too great. :(

That's probably related to all the other chemicals they use at airports (eg forever chemicals in fire retardant). 100LL (100 octane low lead) is only used in small piston engines, which is a very small population. They're trying alternatives that don't use lead, but I'm reading that the top contender is eating through paint and possibly gaskets and seals in the plane, which isn't safe either.

Yeah, fuels are funny like that, rocket fuel kept dissolving chunks of ground crew for the longest time

I can't tell if this is a joke or legit lmao

A bit hyperbolic but seriously, look up hypergolic propellants.

Yes. My boomer father drives to airports to get leaded gas for his lawn equipment and generators. He thinks I'm over reacting when I refuse to be near any of that shit when it's running.
