The council had this to say about leaded gasoline: Report on Gasoline "Despite the rapid increase in the use of leaded gasoline, the high degree of dispersal of these burned additives has prevented a concommitant rise in atmospheric concentrations of lead. The average lead content of the air in most major cities has not changed greatly over the last 15 years. "From the point of view of contamination of the total environment with lead, the lead-using industries have contributed more than has the single source of combusted leaded fuel. Two or three times as much lead is added to the total environment in the form of paint pigments and metallic products as in the form of lead alkyls.
