Abstract: | In this study, concentration of uranium was determined in urine samples collected from 400 Brazilian children (6–14 years old) from different geographic regions. The mean concentration was 33.2 ng/g creatinine. Urinary concentrations of uranium were found to have region and age as predictors. The concentrations of uranium were higher in the South, Southeast and Central-West than in the other regions of Brazil. Moreover, higher concentrations of this element were found in younger children (<?10 years old). To the best of our knowledge, this is the first study to report the exposure of a Brazilian population to uranium. |
