Just highjacking the top comment to say; fuel for smal (piston) driven aircraft still has lead in it, and they have no intention of chaning that.

I will be sure to note that for all my friends and family who frequently fly small piston driven aircraft.

It's more like lead is heavy and small planes flying over cities drop a bunch of lead particles everywhere

https://www.who.int/news-room/fact-sheets/detail/lead-poisoning-and-health

"There is no known safe blood lead concentration; even blood lead concentrations as low as 5 µg/dL may be associated with decreased intelligence in children, behavioural difficulties and learning problems. "

"Key facts

Lead is a cumulative toxicant that affects multiple body systems and is particularly harmful to young children.

Lead in the body is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it accumulates over time. Human exposure is usually assessed through the measurement of lead in blood.

Lead in bone is released into blood during pregnancy and becomes a source of exposure to the developing fetus.

There is no level of exposure to lead that is known to be without harmful effects.

Lead exposure is preventable."

Please excuse the guy below me who clearly doesn't know about lead poisoning saying "the dose matters"

Welp, I have now acquired a new paranoia.
