Uhh, no cars are emitting lead anymore? AV gas, maybe, if the field is near an airport that is a potential risk.

  You can buy leaded fuel for racing. In theory lead contamination could be an issue near a speedway. https://www.sunocoracefuels.com/fuels https://www.sunocoracefuels.com/fuels

  I guess he meant general soot from burned fuel, as much if not more toxic than lead itself.
