| مستخلص: | Communities Atapo Culebrillas and Santa Teresa, in Guamote canton, Chimborazo province, have shown the presence of dental fluorosis, likely among other factors, because of drinking water conditions in these communities. Therefore a characterization of the water from these sources identified fluoride ion as analyte, exceeding the permissible ceiling under Ecuadorian legislation TULSMA (1.5 mg/L), as suspect of the dental fluorosis presented in the area. A monitoring plan to quantify fluoride during 4 months was implemented, analyzes were performed at the Center for technical services and environmental technology transfer CESTTA, of the Escuela Superior Politécnica de Chimborazo. Hazard Index (IP) was calculated allowing us to determine that the population of these communities Atapo Culebrillas (2.22) and Santa Teresa (1.93) are in toxicological risk, because the results of (IP) exceed the reference value recommended by the EPA (<1). This research also proposed the Nalgonda method to reduce the fluoride content in the water, the most effective dose in reducing the fluoride content to safe limits for human health was found to be 3 mL of aluminium sulfate 0.075%, plus 0.05 g of calcium carbonate, and 1 hour as settling time. |
