    Small airplanes still use a lot of 100 low lead avgas. At least jet fuel is unleaded.

        Dumb question (perhaps the lead getting to me) but I’ve long wondered what the practical implications of this are. Does this mean the exhaust is littered with lead that gets aerosolized into the air as the plane darts across the sky? To what extent does that impact lead levels acutely versus background levels, etc.
