OBJECTIVES: This study was performed to determine the reference values of blood lead, manganese, aluminium, and silicon in healthy adults. METHODS: The subjects were 132 (67 male and 65 female), and classified to three age groups (< or =39, 40~49, and 50< or =). Blood lead, manganese and aluminium were analyzed by atomic absorption spectrophotometer, and blood silicon was analyzed by direct current plasma optical emission spectrometer. RESULTS: Blood lead levels(geometric mean, S.D) were (3.49, 1.70) microgram/dL in male and (3.04, 1.65) microgram/dL in female, but the difference is not significant, and there was no significant difference between age groups. Mean blood manganese level was 0.99+/-0.41 microgram/dL, and there was no significant difference between sex or age groups. Mean blood aluminium level was 0.59+/-0.35 microgram/dL, and there was no significant difference between sex or age groups. Mean blood silicon level was 54.41+/-27.64 microgram/dL in male and 43.34+/- 23.51 microgram/dL in female, and the level in male was significantly higher than that in female (p<0.05). There was significant difference between age groups, and the oldest showed the highest level in male (p<0.05), but no significant difference between age groups in female. CONCLUSIONS: Authors hope that this study would provide basic data for determining reference values and evaluating health effects.
Key words: Lead; Manganese; Aluminium; Silicon; Blood concentration
