The dose makes the poison, we can see in blood lead levels over time that we’ve basically solved the problem by eliminating it from car exhaust, which we breathe pretty regularly.
If you live within 1 mile of an airport you will have high amounts of lead in your blood. Maybe not as much as before, but still higher than there should be.
We’re finally able to start reducing that. Just last year, the FAA approved the use of unleaded aviation gasoline in all spark-ignition aircraft designed for 100-Low-Lead.
They’ve also fairly recently authorized compression-ignition (“diesel”) engine swaps in some of the most popular piston-powered GA aircraft, allowing them to burn cheaper, more efficient jet fuel instead of gasoline.
I hate to break it to you, but they never stopped using it in airplanes.
