In this study the air lead levels and blood lead levels in the general population of Torino and Trieste are reported. These are two sensitive and specific classic markers able to documenting the effects of the gradual reduction of the lead in gasoline during the last twenty years. The comparison between air lead pollution in Torino (0.57 μg/m 3) and Trieste (0.72 μg/m 3), shows a significative difference in winter 1996/97. Nevertheless, the mean of air lead in Trieste can be compared to that one of Turin of which the hystorical trend is reported. The haematic lead level (Pb blood) of the 202 subjects of Turin and of the 152 subjects of Trieste evidenced means of 6.98 and 6.55 μg/dl, respectively. The successive sugrouping of the two samples for sex and age evidenced higher values of Pb blood for males and oldest. The analysis of the variance carried out in relation to the smoke habit and to the alcool comsumption has finally evidenced different responsibilities of these two kind of exposures in the distribution of Pb blood. However, the effectiveness of the reduction of lead in gasoline in the reduction of risk for environment and humans is confirmed.
