In 1991 an Italian law will impose a lead reduction in gasoline from 0.4 to 0 g/l. In the present paper we show the actual level (1988) of contamination in Turin city air, in relationship to: lead, some Volatile Halogenated Hydrocarbon and carbonyls that are also bound (directly or indirectly) to emissions from automobiles filled with leaded gasoline. The results confirm the presence in atmosphere of some important "risk factors" for public health that could be substituted with some other ones.
