Lead in particular is nasty and still in use for aviation fuel:
>the most commonly used grades of avgas still contain tetraethyllead (TEL), a toxic substance used to prevent engine knocking (detonation), with ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline
- stephen_g 7y agoDefinitely, but it’s worth noting for people who are unfamiliar - avgas isn’t jet fuel - it’s only used in small piston planes, not anything with turbine engines. It’s still a problem because there are plenty of that kind of aircraft, but most commercial aviation isn’t using leaded fuel.
- dsfyu404ed 7y ago>It’s still a problem because there are plenty of that kind of aircraft, Yeah. But those aircraft don't tend to inhabit the airspace around cities. Pretty much all small commercial aviation in the lower 48 is going to be running turboprops that use normal jet fuel (basically diesel). A suburban airport that actually has a meaningful GA presence is going to put far more lead into the air.
