Monitoring and prediction of high fluoride concentrations in groundwater in Pakistan.
3.3. Health risk map A health risk map was made using the optimal cut-off value of 0.47 (Fig. 5). It identifies numerous densely populated regions where people rely on groundwater associated with high fluoride. In total, over 13 million people are estimated to be potentially affected by fluoride contamination in groundwater, which is 6.0% of […]

High levels of fluoride in groundwater from Northern parts of Indo-Gangetic plains reveals detrimental fluorosis health risks.
Highlights This study provides an overview of fluoride distribution and health risks in the fluoride endemic region of Northern Indo-Gangetic Plain. Groundwater fluorides concentration exceeded the safe drinking water limit in 98% of sampling locations. Health hazard index (HQFluoride) exceeded the unitary value in all the individual groups signifying that the study region is under […]
