Basal levels of mercury in urine were determined in 108 children (54 female, 54 male) without known exposure to the metal. Age range was 6-12 years old. They lived and studied in San Diego County, Carabobo State. Mercury in urine analyses were made by atomic absorption with cold vapor. Samples were corrected by creatinina concentration (Ct) by the modified Jaffe method. Geometric mean for mercury in urine was 1.18 μg/L and 1.22 μg/g Ct (Ct corrected). There was no statistical association between mercury in urine and sex. Mean value of mercury in urine in children aged 10-12 years old (1.45 μg/L) was statistically higher (P< 0.05) than the other ages. The higher Ct corrected mercury in urine (1.30 μg/g Ct), was obtained in the range of 8-9 years old, with no statistical difference with the others age ranges. The results obtained allow to have mean basal values of mercury in urine in a scholar population, in order to provide a tool for further studies which could need reference values of mercury in urine in children.
