英文摘要	Fluoride contamination in groundwaters of a rural region in semi-arid Western India has been studied using combination of geochemical-and-isotopic techniques, in conjunction with Health Quotient assessment approach. The objective of this study is to determine the sources and controls on fluoride content and to evaluate probabilistic non-carcinogenic risk associated with its long-term consumption. F- ranges from 0.3 to 12 mg L-1, shows high spatial variability, and similar to 35% of the samples have F- > 1.5 mg L-1 (WHO maximum limit for drinking). Two sources are identified: high F- results from water-rock interaction of F-bearing minerals in granites and gneisses, while phosphate fertilizers can contribute up to similar to 0.46 mg L-1 of groundwater F- that can be significant for low F- samples. High F- samples are characterized by high pH, Na and alkalinity, and low Ca. Calcite precipitation drives the solubility of F-bearing minerals. Kinetic fractionation of water isotopes (O-18 and H-2) demonstrates that evaporation plays role in enriching groundwater F-. Non-carcinogenic risk, estimated by Hazard Quotient (HQ(oral)(F)), ranges from 0.13-5.72 to 0.26-11.86 for adult and children, respectively. Conservative estimate shows that similar to 0.467 million of adults and similar to 0.073 million of children in four sub-districts are under the risk of fluorosis-while the residents of other five sub-districts remain safe from it. Finally, we suggest stakeholders to install F- treatment plants to ensure the health safety of local residents in the high-risk zones, create awareness in farmers for optimum use of fertilizers, and promote rainwater harvesting, for better management of groundwater resources and quality in the region.
