“…The alkaline pH can influence CaF2 activity and favors the mobilization of F − from soil and weathered rocks into groundwater. This assumption was also formulated by other researchers [64][65][66]. The enrichment of F − can also be influenced by the ratio between HCO3 − , Na + and Ca 2+ in groundwater, as confirmed by Saxena and Ahmed [67], Rango et al [68], and Kimambo et al [64].…”

Studying the quality and health risks of groundwater is of great significance for sustainable water resources utilization, especially in arid and semi-arid areas around the world. The current study is carried out to evaluate the quality and potential health risks of groundwater in the Tongchuan area on the Loess Plateau, northwest China. Water quality index (WQI) and hydrochemical correlation analysis were implemented to understand the status of groundwater quality. Daily average exposure dosages through the oral and dermal contact exposure pathways were taken into consideration to calculate the health risks to the human body. Additionally, graphical approaches such as Piper diagram, Durov diagram and GIS mapping were used to help better understand the results of this study. The WQI approach showed that 77.1% of the samples were of excellent quality. The most significant parameters affecting water quality were NO3−, F−, and Cr6+. The health risk assessment results showed that 27.1% and 54.2% of the samples lead to non-carcinogenic risks through oral intake for adults and children, respectively. In contrast, 12.5% of the groundwater samples would result in carcinogenic risks to the residents. This study showed that the WQI method needs to be supplemented by a health risk evaluation to obtain comprehensive results for groundwater quality protection and management in the Tongchuan area.

“…Several studies have been conducted around the world to demonstrate the link between high‐fluoride water and fluorosis, along with WHO, US‐EPA, and UNESCO. Researchers conducted a massive study on the distribution of fluoride and the occurrence of fluorosis in the most vulnerable areas in India (Ayoob & Gupta, 2006; Raju, Dey, & Das, 2009; Vithanage & Bhattacharya, 2015). Out of 32, a total of 17 states/provinces in India are reported to have endemic fluorosis (Mukherjee & Singh, 2018; Yadav, Bansal, Yadav, & Kumar, 2019).…”

This study aimed to carry out a systematic review of meta‐analysis and risk assessment of the global pooled concentration of fluoride and identify the influencing factors of fluoride loads in groundwater. The study extracted data from 36 most prevalent regions of 20 countries in the world through various search engines using keywords as well as Boolean operators and follows the PRISMA statement in every phase of literature searching. The study illustrated the pooled concentration of fluoride in the selected 20 countries was 2.1267 mg/L (1.650, 2.604) at 95% confidence interval, which was higher than the WHO standards limit of 1.5 mg/L. The results of the meta‐analysis suggested that pH, Na, HCO3 and rainfall was significantly positively correlated (r = ~0.4; p ˂ 0.05) to fluoride and has a weak correction with the other parameters such as local temperature, altitude, water depth, EC, Ca, and Mg (r = −0.064 to +0.214; p ˂ 0.05). Concerning, the risk assessment through oral and dermal route exposure revealed that the consumers in most of the regions were at considerable risk, and the children were more vulnerable than the adults (THQ > 1). The study findings would help to take measures for safe water supply in the affected areas. Practitioner points The calculated pooled concentration of fluoride was 2.1267 mg/L (1.650, 2.604) at 95% CI in groundwater of the study areas. Climatic conditions and lithological composition are the key controlling factors for groundwater fluoride contamination. Semi‐arid and arid regions are significantly affected by fluoride rather than humid areas. Regarding fluorosis in selected regions, children (78%) are more vulnerable than adults (23%).

“…Ô nhiễm F trong nước uống là nguyên nhân chính trong tất cả các nguyên nhân gây bệnh dental fluorosis. Các kết quả nghiên cứu trước đây đã cho thấy 25 quốc gia trên thế giới có nồng độ florua cao trong các nguồn nước và khoảng 200 triệu người sống dựa vào các nguồn nước có chứa quá nhiều florua gây hậu quả nghiêm trọng đến sức khỏe người tiêu dùng [4][5]. Các quốc gia được ghi nhận trong bản đồ ô nhiễm fluor thế giới điển hình bao gồm Ethiopi (8 đến 10 triệu người bị ảnh hưởng; [6]); Mexico (5 triệu người bị ảnh hưởng; [7]); Argentina (1,2 triệu người; [8]).…”

Dental fluorosis-a major, but preventable, oral diseases and public oral health problems-related with exceeded the fluoride level in natural groundwater sources. Dental fluorosis remains as a major public health problem worldwide, including Vietnam. Previous studies carried out since the 2000s demonstrated a link between dental fluorosis and increased fluoride levels in drinking water of Ninh Hoa town, Khanh Hoa province. The aim of this study was to determine the temporal variation of district's population, who at risk for dental caries or dental fluorosis, with questionair survey in Ninh Hoa town. The results indicated that the rate of population at risk for dental fluorosis, has been decreased in comparision with previous studies. In especially, in the vulnerable area with high fluorid zones like Ninh Xuan, Ninh Phung wards (> 6mg/L), the number of population at risk decreases to only 18 and 12%, respectively. Overall, only 25% district's population were risk of potential dental fluorosis. It is the results from implementation of drinking water supply projects from government. However, the long-term operation of the replacement of groundwater project need to be further strengthened. In addition, a further study on dental fluorosis and sources of F should be carried out.
