GALICIA CHACON, Luis et al. Analysis of drinking water fluoride concentration in Tlahuac, Mexico City. Rev. Int. Contam. Ambient [online]. 2011, vol.27, n.4, pp.283-289. ISSN 0188-4999.

A descriptive study of the water of 18 areas in the municipality of Tláhuac, México City, was conducted with the objective of assessing the fluoride concentration in drinking water. 144 water samples obtained from the wells and neighboring areas of the Tláhuac municipality were analyzed. The fluoride content was analyzed and quantified as established by the Mexican guideline NMX-AA-077-SCFI-2001. Fluoride concentration in water samples ranged from 0.44 to 1.28 ppm, with an average concentration of 0.86±0.19 ppm. Fluoride levels found in most wells in the study area were higher than those established by the regulations regarding the consumption of fluoridated salt. It is essential that health authorities implement preventive measures to avoid the consumption of fluoridated salt and other additional fluoride due to increase dental fluorosis in México City.
