Objective:The aim of this study was to investigate the blood lead levels of children after introducing lead-free gasoline in Beijing.Methods:The blood lead levels of 1 360 children,who were out-patients suspected lead poisoning and aged from 2 to 6 years, were determined by Anodic Stripping Voltametry(ASV), and 616 from infants school were in control group. Results:258 children (13.1%) were found to be suffering from lead poisoning (≥10 μg/dl, 1 μg/dl=0.0483 μmol/L). The blood lead levels of children from infants school and children care out-patient department were (4.93±3.3)μg/dl, (6.62±4.57)μg/dl respectively, and significant difference was observed between the two groups(P<0.001). Conclusions: Blood lead levels of children in Beijing and the prevalence of lead poisoning were both relatively declined. Blood lead levels were lower in children from infants' school than from children care out-patient department.
