The fluoride content of some teas available in Australia

A bstract — Analysis of brews of a selection of teas available in Australia using the fluoride ion-selective electrode gave after a five-minute infusion an average fluoride level of (1.34 ± 0.17 ppm) F. Brews of two brands of tea contained >2 ppm F; using fluoridated water a cup of tea made with one of these brands may contain 0.5 mg F. Its potential significance for young children on fluoride supplements should be recognized.
