“…Endemic fluorosis afflicts N260 million individuals worldwide in 25 different nations, and N100 million people in southeast Asia, including India, Pakistan and Sri Lanka (Farooqi et al, 2007a(Farooqi et al, , 2007bAmini et al, 2008;Ravenscroft et al, 2009;Rafique et al, 2009;Kim et al, 2012). Both dental and skeletal fluorosis is a global problem, occurring in various countries, such as Ethiopia, Kenya and Tunisia (Rango et al, 2010(Rango et al, , 2013Olaka et al, 2016;Guissouma et al, 2017), India (Jacks et al, 2005;Vikas et al, 2013), China (Smedley et al, 2003;Guo and Wang, 2005;Guo et al, 2007;Amini et al, 2008;Wang et al, 2009;Currell et al, 2011), Brazil (Souza et al, 2013), and Pakistan (Farooqi et al, 2007a(Farooqi et al, , 2007b.…”

This study investigated the fluoride (F) concentrations and physicochemical parameters of the groundwater in a fluorite mining area of the flood plain region of the River Swat, with particular emphasis on the fate and distribution of F and the hydrogeochemistry. To better understand the groundwater hydrochemical profile and F enrichment, groundwater samples (n=53) were collected from shallow (24-40m), mid-depth (48-65m) and deep (85-120m) aquifers, and then analysed using an ion-selective electrode. The lowest F concentration (0.7mg/L) was recorded in the deep-aquifer groundwater, while the highest (6.4mg/L) was recorded in shallow groundwater. Most groundwater samples (62.2%) exceeded the guideline (1.5mg/L) set by the World Health Organization (WHO); while for individual sources, 73% of shallow-groundwater samples (F concentration up to 6.4mg/L), 42% of mid-depth-groundwater samples, and 17% of deep-groundwater samples had F concentrations that exceeded this permissible limit. Assessment of the overall quality of the groundwater revealed influences of the weathering of granite and gneisses rocks, along with silicate minerals and ion exchange processes. Hydrogeochemical analysis of the groundwater showed that Na is the dominant cation and HCO the major anion. The anionic and cationic concentrations across the entire study area increased in the following order: HCO>SO>Cl>NO>F>PO and Na>Ca>Mg>K, respectively. Relatively higher F toxicity levels were associated with the NaHCO water type, and the chemical facies were found to change from the CaHCO to (NaHCO) type in calcium-poor aquifers. Thermodynamic considerations of saturation indices indicated that fluorite minerals play a vital role in the prevalence of fluorosis, while under-saturation revealed that - besides fluorite minerals - other F minerals that are also present in the region further increase the F concentrations in the groundwater. Finally, a health risk assessment via Dean's classification method identified that the groundwater with relatively higher F concentrations is unfit for drinking purposes.

“…And the anthropogenic sources include leakage from stored pesticides (Kim et al, 2011) and irrigation using high-F − groundwater (Pettenati et al, 2013). Endemic fluorosis has been widely documented in different countries such as India (Jacks et al, 2005;Vikas et al, 2013), Brazil (Buzalaf et al, 2004;Souza et al, 2013), Mexico (Irigoyen et al, 1995), Africa (Gizaw, 1996;Rango et al, 2010;Tekle-Haimanot et al, 2006) and China (Amini et al, 2008;Ando et al, 2001;Currell et al, 2011;Gao et al, 2007;Guo and Wang, 2005;Smedley et al, 2003;Wang et al, 2009). China has more than 41 million victims in 1325 different counties suffering from dental and skeletal fluorosis (Ministry of Health of China, 2010).…”

Este artigo reporta uma investigação científica da hidrogeoquímica básica do Aquífero Bambuí no oeste da Bahia, com ênfase o flúor. Foram amostras de 61 poços durante os anos de 2011 (período chuvoso) e 2012 (período de estiagem). O pH variou entre 6,87 e 8,93, com predomínio de condições alcalinas. As fácies hidroquímicas bicarbonaradas cálcicas (56%), mistas cálcicas (20%) e as fácies bicarbonaradas sódicas (10%) foram as mais representativas no sítio de estudo, em que as concentrações do flúor excederam o limite ótimo local (0.8 mg.L-1) para 30% dos poços, que oscilaram de 0,1 a 6.2 mg.L-1 e média de 0.96 mg.L-1. A análise das Componentes Principais e a composição das amostras de água sugeriram a relevância do intemperismo químico para a mineralização e qualidade da água subterrânea; bem como para compreensão do enriquecimento em flúor. A origem do flúor reflete a importância do intemperismo das rochas que encaixantes do Aquífero Bambuí, e a dissolução de minerais hospedados nestas, para a qualidade da água. Recomenda-se, para o sítio de estudo, investimento público significativo na pesquisa em geociências, saúde pública e na dessalinização das águas salobras. Deve-se, também, priorizar o monitoramento da qualidade da água subterrânea, poluição por nitrato e a vigilância epidemiológica da fluorose dentária relacionada a ingestão dessas águas. Os resultados dessa pesquisa mostram a relevância da gestão dos recursos hídricos para melhora do saneamento básico e para a promoção da saúde pública.
