Costs of IQ Loss from Leaded Aviation Gasoline Emissions
It turns out small aircraft can still use leaded fuel, and the impact of the resulting IQ loss in these highly-trafficked routes is significant. "We find that aircraft-attributable lead contributes to $1.06 billion 2006 USD ($0.01–$11.6) in annual damages from lifetime earnings reductions, and that dynamic economy-wide methods result in damage estimates that are 54% larger."
