“…Fluoride has caused significant contamination of groundwater in many regions worldwide including India [14,15], Korea [16,17], Malawi [11], Pakistan [18], Sri Lanka, West Indies, Spain, Holland, Italy, Mexico countries... Especially, India, East Africa and China have been identified as the countries with the most seriously fluoride-contaminated aquifers [19,20].…”

The communities within Binh Dinh province in the Central Vietnam are reliant on groundwater as their primary supply of domestic and potable water. Meanwhile, it is seriously contaminated with fluoride that causing fluorosis problem for people. This study aims to investigate the link between severity of dental fluorosis rate in a population and fluoride concentration in drinking water in Tay Son area. A total of 50 well-water samples were collected and 220 people were surveyed by questionnaire from 50 households at 3 villages: Tay Phu, Binh Tuong, Tay Giang of Tay Son district, Binh Dinh province, Vietnam. The quantitative assessment of severity of dental fluorosis was done by calculating the Community Fluorosis Index (CFI) using Dean's classification. Result of this study showed that fluoride concentration in well-water varied from 0.31 mg/L to 7.69 mg/L (mean 2.66 mg/L, SD: 2.18 mg/L) with 70 % of well-water samples above the maximum permissible limit of 1.5 mg/L of World Health Organization (WHO) drinking water standard. 100 % people surveyed was suffered from dental fluorosis and Dean scale of dental fluorosis ranged from level 2 to level 5. CFI varied from 3.45 to 4.13 above limit value (0.6). The community seriously suffered from dental fluorosis. The fluoride concentrations and Dean Index have high correlation (r = 0.580, p < 0.0001). Based upon results of this study, it is recommended that the government should supply drinking water with appropriate fluoride content for this community.

“…It is not known whether As contaminates the groundwater in the other densely populated basins. Quaternary aquifers are the most important source of groundwater in these basins (Guo et al, 2007a;Wang et al, 2009;Xie et al, 2009) and, despite waters rich in NaHCO 3 predominate (Currell et al, 2011;Xie et al, 2008), it appears that high As concentrations are exclusively correlated to reducing conditions in the basins (Guo et al, 2003;Li et al, 2007;Xie et al, 2009).…”

a b s t r a c tShanxi Province is one of the regions in northern China where endemic arsenicosis occurs. In this study, stepwise logistic regression was applied to analyze the statistical relationships of a dataset of arsenic (As) concentrations in groundwaters with some environmental explanatory parameters. Finally, a 2D spatial model showing the potential As-affected areas in this province was created. We identified topography, gravity, hydrologic parameters and remote sensing information as explanatory variables with high potential to predict high As risk areas. The model identifies correctly the already known endemic areas of arsenism. We estimate that the area at risk exceeding 10 mg L À1 As occupies approximately 8100 km 2 in 30 counties in the province.
