  • Title: Uranium daily intake and urinary excretion: a preliminary study in Italy.
    Author: Galletti M, D'Annibale L, Pinto V, Cremisini C.
    Journal: Health Phys; 2003 Aug; 85(2):228-35. PubMed ID: 12938971.
    Abstract:
    An estimate was made of daily uranium intake in Italy through human diet and drinking water. The uranium concentration was determined in food, drinking water, and other beverages. Uranium concentration was also determined in a "total diet" sampled in 1999. The total daily dietary intake was estimated to be in the range 2.9-4.8 microg d(-1). The contribution of drinking water to the total uranium intake is sometimes significant as the uranium concentration range in 29 analyzed tap and bottled "mineral" waters is 0.04-5.86 microg L(-1) and the drinking water consumption about 1 L d(-1) or more. Data obtained in this study were compared with data from literature on the uranium daily intake in other countries. Urine samples were collected from 24 male and 14 female occupationally unexposed subjects, 20-50 y of age, living and working in the district of Rome (Italy). The mean concentration found was 10 +/- 7.0 ng L(-1); the inter-subject variability and the daily variability was evaluated. Analyses were performed using ICP-MS.
