  • Abstract: ations of Aluminium in drinking waters (tap water, still mineral water and sparkling mineral water), fruit juices and soft drinks were determined using graphite furnace atomic absorption spectrometry (GFAAS) of samples processed with a HNO3–V2O5 acid digestion pre-treatment. In water samples, Aluminium was determined directly. We verified the sensitivity, accuracy and precision of the method and ruled out matrix interferences. In analysed samples, Aluminium values ranged from 4.2 to 165.3 μg/l in drinking water (n=41), from 49.3 to 1144.6 μg/l in fruit juices (n=47), and from 44.6 to 1053.3 μg/l in soft drinks (n=88). According to the type of container (glass or can) statistically significant differences (P<0.01) have been demonstrated. Considering the mean daily individual consumption of these beverages in Spain, the daily dietary intake of Al supplied by this source is estimated as 156 μg/person/day. This study contributes new data on the Al content of a variety of foods and beverages in Spain and to estimate reliably the total dietary intake of Aluminium.
