Airports’ leaden fallout may taint some kids
People who live below the flight path of piston-engine aircraft — or downwind of airports serving such small planes — are exposed to lead from aviation fuel. A new study now links an airport’s proximity to somewhat elevated blood-lead levels in children from area homes.

I only wish I knew then what I do now.
