Abstract:
The fluoride concentration of 17 bottled waters was measured and compared to the concentration of fluoride reported on the label of each product. There was a great variation in fluoride concentration between the products, ranging from very low in distilled waters to over 4 ppm in a mineral water. The fluoride concentration in seven of the products was more than 0.1 ppm higher than shown on the labels, and the concentration in two of the products was more than 0.1 ppm lower. Due to the high content of fluoride, some of these waters are unacceptable for a child's diet. Conversely, some products contain insignificant amounts of fluoride which may deprive the child of the optimal daily fluoride requirement.
