摘要

Objectives: The aims of this study was to evaluate the fluoride content of bottled drinking water commercially available in Fiji in March 2006; and to report on the labelling of fluoride concentrations. Methods and Materials: Commercially available bottled water in Fiji, in March 2006 was purchased from supermarkets. Three bottles of 11 brands were purchased. Ten millilitres of each water sample was mixed with 2 millilitres of spands reagent; these were then tested for fluoride concentrations using photo spectrometry at wavelength of 580 nanometres. The fluoride concentrations listed on the sample labels were also noted and compared with the results obtained from the spectrometry test. Results: The mean (±standard deviation) of fluoride was 0.09 (±0.05) ppm. None of the brands tested labelled the fluoride concentration in the bottled water. The range of fluoride concentration was between 0.02 to 0.34 ppm. There was also a vast variation of fluoride concentrations within the same brand of product. Conclusions: Commercially available bottled drinking waters in Fiji contain a wide range of concentrations of fluoride and none of the manufacturers labelled the content of fluoride on the bottle. It was also noted that none of the brands contained optimal levels of fluoride.
