Concentration effect and operational parameters on electrodialysis reversal efficiency applied for fluoride removal in groundwater

Abstract The increase in dental fluorosis in young people shows that the methods used to tackle the disease are ineffective. Typically, people around the world use groundwater for most activities, and this is the case of people especially in western Bahia, Brazil. In this region, aquifers can contain anomalous concentrations of fluoride. Thus, it is […]

Who to blame for groundwater fluoride anomaly in São Paulo, Brazil? Hydrogeochemistry and isotopic evidence

Highlights Fluoride up to 10 mg.L-1 is found in groundwater from São Paulo, Brazil. This fluoride is from natural origin. There is no fluorine related to the upper sedimentary aquifer. Fluoride is related to deep groundwater flow in the fractured aquifer. Abstracts Fluoride concentrations up to 10 mg.L-1 have been described in the groundwater of […]

Fluoride concentration and labeling requirements of mineral bottled water from Brazil

ABSTRACT Introduction: Mineral waters usually contain natural fluoride (F) in their composition, but the benefits and risks of the concentrations found are not clearly informed. Objective: The aim of this study was to determine the F concentration in mineral bottled waters and to check if the concentrations found: (1) matched with those informed on the […]
