| Résumé: | The main objectives of this study are to determine the presence of antimony in water stored in polyethylene terephthalate bottles and the influence of temperature and time over the migration levels. For this purpose, Sb determination was carried out in water at different experimental conditions: storage for one to three weeks at 25 to 80 ℃; long-term (six months) storage at room temperature between 16 and 24 ℃ and storage in car during summer which is a common consumer's habit. In addition, water quality analysis was developed after different time-temperature storage conditions. All the samples at the end of their storage conditions were analyzed by inductively coupled plasma mass spectrometry. The limit of detection and quantification were 0.50 and 0.80 µg/L, respectively. The results for the bottled water stored during six months indicated that the average Sb concentration was 0.332 ± 0.015 µg/L. This value is below the European maximum permissible migration level of 5 µg/L. With regard to the newly bottled water, no Sb was detected at the initial time for all temperatures studied. However, the Sb concentration in water increased with both time and temperature. The levels of Sb started exceeding the European limits when the samples were stored at 60 ℃ for two weeks |
