Fluoride Content of Bottled Drinking Water in Chennai, Tamilnadu
Context: The optimum level of fluoride in drinking water is 0.7 to 1.2 ppm. Decreased fluoride concentration leads to increased risk of caries and increased concentration can lead to dental or skeletal fluorosis. One crore liters of water is supplied to Chennai and surrounding areas through pouc...

The range of fluoride level in tested samples was between 0.27 to 0.59. Only one brand’s label had information regarding the fluoride content. Conclusion: Standardization of fluoride levels in bottled waters and labelling of fluoride content should become mandatory.https://jcdr.net/articles/PDF/6594/14691_CE(Ra1)_F(GH)_PF1(PAK)_PFA(AK)_PF2(PAG).pdfbottled waterspadns colorimetric analysis |

Context: The optimum level of fluoride in drinking water is 0.7 to
1.2 ppm. Decreased fluoride concentration leads to increased
risk of caries and increased concentration can lead to dental
or skeletal fluorosis. One crore liters of water is supplied to
Chennai and surrounding areas through pouches and bottles
which carters about one third of city population.
Aim: The aim of this study is to determine the fluoride
concentration in top 10 bottled waters in Chennai and to check
the accuracy of their labelling.
Materials and Methods: Top selling bottled waters, 6
multinational and 4 Non- multinational brands were selected
for the study. Three different batches of each brand were
purchased. The labels of the bottled were removed after
collecting the details regarding fluoride content. All the bottles
were numbered and sent for fluoride content analysis using
SPADNS calorimetric method.
Results: All the brands and batches which were analysed for
the study had less than optimal fluoride content and there is
a significant variation in fluoride concentration of each brand
and among different batches of same brand bottled waters.
The range of fluoride level in tested samples was between 0.27
to 0.59. Only one brand’s label had information regarding the
fluoride content.
Conclusion: Standardization of fluoride levels in bottled waters
and labelling of fluoride content should become mandatory. |
