In many developing countries, non-lead gasoline policy has been promoting these years to prevent the air-pollution related health risks. Japan had already completed the non-lead gasoline system in 1983. In this study the effect of the Japanese non-lead gasoline policy was examined from the both aspects of the ambient air pollution control and the health risk reduction.<BR>The lead exposure to the reference Japanese was evaluated through the both pathways of dietaryand respiratory intake, and the lead concentration in blood was evaluated by using the physiologically based pharmacokinetic model (PBPK model). The lead concentration in ambient air and the respiratory intake was reduced drastically by the non-lead policy, however the total lead exposure was not because of the larger contribution of the dietary exposure to the average reference Japanese. The present lead exposure level is low enough for keeping the lead concentration under the limit concentration in blood.
