Determinación de flúor en agua en plantas potabilizadoras y escuelas de las parroquias rurales: Paccha, Cumbe, Quingueo, Octavio Cordero, Tarqui, Victoria del Portete, Baños, Nulti y Santa Ana del cantón Cuenca

Abstract

Fluorides are essential components, which have beneficial effects on dental and bone tissue. However, when fluoride intake exceeds the permissible limit, abnormalities such as dental fluorosis can be observed. In the canton of Cuenca there has been an increase in the prevalence of this disease, with the possibility that this is due to the existence of fluorides in water sources. Objective: The objective was to analyze the concentration of fluoride in water of the collection and storage tanks in the purification plants and of 14 schools belonging to 9 rural parishes of the Cuenca canton (Paccha, Cumbe, Quingueo, Octavio Cordero, Tarqui, Victoria del Portete, Baños, Nulti and Santa Ana). Methodology: The quantitative study of descriptive fuel. In total, 56 water samples were collected from three strategic areas that were: collection tank, storage tank and selected schools. A monitoring plan was executed with a duration of two months (April and July 2019), this period represents the rainy period and the dry period respectively. The method by which the fluoride analyte was determined is the 4500 F‾ selective ion. Results: The analyzed data containing the variations of fluoride in water of the study areas are between 0.0 - 0.12 mg / L of fluoride. Conclusions: It is concluded that the water supply sources of the rural parishes of the Cuenca canton contain fluoride limits lower than those recommended by the INEN and WHO standards.
