Hydrogeochemical and isotopic controls on the source of fluoride in groundwater within the Vea catchment, northeastern Ghana

Fluoride in groundwater sources in Ghana: A multifaceted and country-wide review

“…Ghana grapples with the pervasive challenge of fluoride toxicity, a subject that has garnered substantial research attention from scholars such as Apambire et al [ 23 ], Sunkari et al [ 19 ], Zango et al [ 20 ], Yidana et al [ 25 ], and Firempong et al [ 80 ]. These investigations have primarily honed in on specific geographic areas, primarily within Northern Ghana.…”

“…Within this optimal range, fluoride is beneficial for dental health and essential for bone growth and maintenance [ 16 , 17 ]. However, when fluoride concentrations exceed 1.5 mg/L −1 , it can lead to severe health issues, including dental discoloration, skeletal fluorosis, physiological disorders, and kidney malfunctions, among others [ [18] , [19] , [20] ]. It is worth noting that fluoride concentrations within the range of 0.0–0.5 mg/L −1 in the human body can result in dental cavities [ 21 ].…”

Characterization of groundwater in the 'Tamnean' Plutonic Suite aquifers using hydrogeochemical and multivariate statistical evidence: a study in the Garu-Tempane District, Upper East Region of Ghana

“…Sedimentary origins such as dolomite and magnesite minerals may also contribute to magnesium in groundwater. There is a significant correlation between Mg 2+ and Ca 2+ (r = 0.91), indicating the weathering and dissolution of magnesium -bearing minerals such as biotite, chlorite, and hornblende, which may be found in the host plutonic rocks in the catchment (Zango et al 2020). However, there is a non-significant correlation between Mg and EC (r 2 = 0.36), suggesting minimum magnesium ions in solution as a single salt (Tutmez et al 2006).…”

Assessment of the hydrogeochemistry of shallow water aquifers using corrosion indices and geospatial techniques in the regions of the Brahmaputra river basin, India

“…10 The groundwater quality is governed by various geochemical mechanisms, include weathering, mineral dissolution, aquifer-rock interaction, ion exchange, and evaporation. 11,12 In recent years, anthropogenic activities have resulted in the dissolution of harmful pollutants during groundwater recharge and abstraction. Therefore, it has become imperative to regularly monitor the groundwater quality.…”
