Abstract
Objectives: The aim of this study was to evaluate the concentration of fluoride (F) in household salt marketed in Montevideo, Uruguay. Methods: Fourteen household salt brands marketed in Montevideo, Uruguay were analyzed to determine the F concentrations. Salt samples were prepared and F concentrations were determined using a fluoride-specific electrode connected to an ion analyzer.Results: Most of the salt brands showed values lower than 250 mgF/kg. Coarse salt samples showed higher F concentrations compared to the refined salt samples (p < 0.05). Salt brands contained sodium fluoride presented higher F concentrations than salt brands contained potassium fluoride (p < 0.05). Only two brands had F concentrations close to that informed in product packages. Conclusions: Household salt brands marketed in Montevideo (Uruguay) present a great variability in their F concentrations.
