Abstract

The findings between the relationships between the geological/geochemical environment and the health of populations, based on the effect of the chemical element fluor of geogenic origin present in the groundwater of several locations in the State of Bahia, Brazil present numbers that indicate values of the order of 0.4 mg/L F, as a risk to populations, 0.4 to 0.8 mg/L F as a protective factor and >0.8 mg/L F as a myth prone to dental fluorosis.

Analyses of water for human consumption, in particular fluor concentrations, represent an important planning and decision-making tool for managers and municipal bodies regarding water fluoridation and the presence of natural fluoride. The results presented can promote prevention strategies for a series of diseases, including dental fluorosis and highlight, in a striking way, the importance of geogenic materials and the health of populations.
