Abstract
In many countries, the leaded gasoline regulation has been carrying on these years to prevent the airborne lead related health risks. In this study, the Malaysian leaded gasoline regulation was examined from the viewpoint of the health risk reduction. The lead exposure to reference Malaysian was evaluated through the both pathways of dietary and respiratory intake, and the lead concentration in blood (PbB) was estimated by using the physiologically based pharmacokinetic model (PBPK model).
Consequently, the present lead exposure level of Malaysian is low enough for keeping PbB under the limit concentration of 30μg/dL. Most of Malaysians are holding PbB under the lower limit of 10μg/dL.
