The exhaust gases formed by the burning of lead rich motorfuel add a quarter of a million tons of lead to the earth's atmosphere per annum. Sweden alone contributes to this environmental disturbance with 1.2-1.4 millions kilograms per annum, of this very toxic metal. People living in cities and people of certain professional categories, related to motor vehicles and motorfuel, are especially exposed to the extra impact which lead particles in air have. The mean lead concentration in city air is about 2-4 microgram/cu M, with peaks during the rush hours at 20 microgram/cu M. In big cities the amount of lead in the blood of the population is about 5-20 microgram/ml, while the level is especially exposed to professions e.g. chauffeurs, policemen etc is up to about 35 microgram/ml. The author goes on to describe the symptoms of lead poisoning. He concludes that children of cities are especially in the risk zone because: (1) children are more sensitive to lead poisoning, (2) children consume more food compared to body weight than adults, (3) children absorb lead about five times as effectively, in the canals of the abdomen and intestine, as compared to adults, (4) children in cities are more exposed to lead in the air, through their playing habits, than adults.
