“…A study in Paraíba in the north-eastern region of Brazil found that 73% of the water samples taken were presented with low levels of fluoride which was below 0.5 mg/L (16). Other than that, a study in the urban area of Chongqing, China, (17) discovered that the average level of fluoride in drinking water was 0.238 ± 0.045 mg/L, with a range of 0.100 to 0.503 mg/L. Another author (18) reported that in the coastal region of Bang-ladesh, approximately 55% of samples exhibited fluoride deficiency, which was below 0.50 mg/L and may cause dental caries.…”

Introduction: To determine fluoride levels in gravity feed system water of Sungai Mas Village in Sungai Lembing, Kuantan, and its related potential health risk due to fluoride exposure from drinking water among adult indigenous people in the area. Methods: Adults who have lived in Sungai Mas Village, Pahang, for more than one year and use gravity feed system water as a drinking water source were selected as respondents. A set of questionnaires was used to determine socio-demographic and information on gravity feed system water usage among the respondents. A handheld Fluoride low-range (LR) Color-imeter and a portable pH meter were used to measure fluoride levels and pH in water samples, respectively. A body weight scale was used to measure the weight of respondents. Results: A total of 80 indigenous people in Sungai Mas Village were chosen as respondents. From 80 water samples col-lected, 98.75% had fluoride lower than the Malaysian National Standard for Drinking Water Quality’s permissible level (0.4 – 0.6 mg/L), while 1.25% had a fluoride level within the said level. Fluoride ranged from 0.10 to 0.41 mg/L, while pH ranged from 7.67 to 8.20, meaning 100% of the water samples had pH within the permissible level. The Hazard Quotient (HQ) was less than 1 (HQ < 1). Conclusion: Water samples in the study area had low natural fluoride, which is insufficient to eradicate dental caries. Meanwhile, the value of the hazard quotient suggests that adults in Sungai Mas Village may not be at risk of developing dental and skeletal fluorosis.

“…Geologically, the area is essentially located in the Daba Mountains. The strata consist of Triassic carbonate rocks (e.g., limestone and dolomite) and Permian clastic rocks (e.g., black shale, siliceous shale, interbedded gray-black thin-medium-bedded mudstone) [21,22]. Based on its hydrogeological characteristics, the groundwater is categorized into karst water (KW) in carbonate rocks and fissure water (FW) in clastic rocks [23,24].…”

Elucidating the hydrogeochemical processes and quality assessment of groundwater holds significant importance for its sustainable development. In this paper, 53 groundwater samples were collected from a typical agricultural area in the northeastern Chongqing municipality in SW China. The integration of multivariate statistical analysis, ion ratio analysis, geomodelling analysis, the entropy water quality index, health risks assessment, and sensitivity analysis was carried out to explore the hydrochemical processes and quality assessment of groundwater in this study. The statistical results reveal that the cationic concentrations followed the order of Ca2+ > Mg2+ > Na+ > K+, while the anionic components were in the order of HCO3− > SO42− > NO3− > Cl−. Based on the Piper trilinear diagram, the hydrochemical types were shown as Ca-HCO3 and Ca-Mg-HCO3 types. Hierarchical cluster analysis indicated that the groundwater samples could be categorized into three groups. The hydrochemical compositions were primarily influenced by water–rock interactions (e.g., carbonate dissolution and silicate weathering). In terms of irrigation suitability, the sodium adsorption ratios (SARs) ranged from 0.05 to 1.82, and the electrical conductivity (EC) varied from 116 to 1094 μs/cm, indicating that most groundwater samples were suitable for irrigation. The entropy-weighted water quality index ranged from 15 to 94, suggesting that the groundwater samples were suitable for drinking purposes. Non-carcinogenic human health risks followed the order of children > adult females > adult males, within the average values of 0.30, 0.21, and 0.18, respectively. Sensitivity analysis showed that the parameters had the weight order of NO3 > body weight (BW) > ingestion rate (IR) > exposure frequency (EF). Hence, we recommend prioritizing the management of areas with high salinity levels, while avoiding the excessive use of nitrogen fertilizers, raising awareness among local residents about safe groundwater, and providing robust support for the sustainable development of groundwater in typical agricultural areas.

“…A relação flúor-saúde têm importância mundial porque a ingestão de águas naturais com níveis tóxicos de fluoreto representa uma relevante via de exposição (KOMATI; FIGUEIREDO, 2013;RAJU, 2017;ABIYE et al 2018;KUMAR et al 2018;RASHID et al 2018). Este elemento é o mais eletronegativo da tabela periódica, muito reativo e ocorre como íon fluoreto em meio aquoso, sendo um oligoelemento essencial aos seres humanos, cuja deficiência ou excesso pode provocar agravos à saúde (HEM 1985;CRAIG et al 2018;YU et al 2018;ZHENG et al, 2020).…”

A relação flúor-saúde tem sido mundialmente estudada, especialmente quanto aos riscos à saúde decorrente da exposição aos níveis tóxicos de flúor a partir da ingestão de água subterrânea. Por isso, esta pesquisa teve como objetivo investigar a distribuição dos níveis do fluoreto nas águas subterrâneas e seus significados à saúde no município de Serra do Ramalho, Bahia, Brasil. Coletou-se amostras de água de 26 poços tubulares para as análises das variáveis físico-químicas, íons principais e do fluoreto (SPADNS). Obteve-se restrições de potabilidade quanto ao nitrato para 40% das amostras, que pode ser relacionada às falhas do saneamento. Registrou-se níveis do fluoreto que excederam o limite ótimo local de potabilidade (0,8 mg.L-1) para 23% das amostras, onde o consumo destas águas representa um fator de risco de fluorose dentária à população infantil. Considera-se imprescindível que o monitoramento do flúor nas águas de abastecimento público, a desfluoretação, quando cabível, e a vigilância em saúde abranjam os múltiplos usos da água as dimensões biogeofísicas, econômico-sociais e culturais dos sujeitos sociais deste município. Ademais, deve-se fomentar a formação de profissionais que considerem as relações entre ambiente e saúde.
