Acknowledging that there is no safe amount of lead exposure, the amount of lead that "is being sprayed all over you" from a tiny handful of piston airplanes is minuscule compared to what we were all exposed to prior to the mid 70s. Like many orders of magnitude. I'd be concerned if I worked at the airport pumping gas or something.

There is unleaded airplane fuel, although leaded fuel is still used. What I have been told is that it would take some time for the unleaded airplane fuel (which is compatible with the existing airplanes that use leaded fuel) to be distributed to enough places to be commonly available enough, which it isn't yet.

Yeah it's absurd how aviation is somehow exempt from these rules, especially since piston engine aircraft carry virtually no vital role in anything except people flying them for fun. There have been viable alternatives for a long long time now.

I guess people who have money for personal airplanes also have the money to lobby when it matters for their interests. Pricks, I hope they die of dementia.
