This seems like such a cop-out excuse. We'd rather harm potentially millions of people with toxic materials rather than inconvenience a few dozen aviation enthusiasts. Progress moves forward, if these old engines can't function in this new world they should be scrapped and replaced with something that can do the job.

And BTW, general aviation has been asking for leaded avgas to be dropped for decades now. The holdup is not the pilots or plane owners but the goddamn FAA [0].

Do you know of any research focused on lead-related health issues from areas of popular general aviation? Or around the supply chain for leaded fuel?

There are a few studies done. Here is one carried out by the NIH around NC. [0]

In summary they are noticeably elevated but not as high as, an example, Flint Michigan. Lead blood levels do fall off precipitously after ~2km.

This is really good thank you. Worthy of a follow-up submission on HN of its own since we're pretty deep into comments here.

Note that this study is specifically focused on North Carolina. I'm curious if similar research has been done in the Western US. California in particular is very popular for GA. Here's the top 10: https://generalaviationnews.com/2020/02/03/top-10-busiest-ge...

To save people the full read, here is the most relevant sentence:

> children living within 500 m, 1,000 m, or 1,500 m of an airport had average blood lead levels that were 4.4, 3.8, or 2.1% higher, respectively, than other children.
