“…Recent reports advocate that more than 200 million people from the 25 nations in the world are under the threat of the fluorosis problem [5][6][7][8]. Typically, the endemic fluorosis is more severe in parts of China [9][10][11], Turkey [12], Korea [13], Mexico [14], India [8,[15][16][17][18][19][20][21][22], Africa [23], Syria, Jordan, Ethiopia, Sudan, Tanzania, Kenya and Uganda [24][25][26][27][28][29].…”

“…In other words, the endemic fluorosis belt (EFB, Telangana state in India) has also evidenced that more populace suffers from the various health risks due to the intake of highly fluoride-contaminated drinking water. Therefore, many groundwater scientists and researchers have adopted the human health risk assessment model to delineate the adverse effect of ingesting fluoride-contaminated water; Adimalla and Li [18] studied on groundwater quality and potential health risks from fluoride content in drinking water in the rock-dominant semi-arid region of Telangana and found that children are more adversely affected by health risks due to intake of elevated fluoride concentration in drinking water. Similar results were reported in various regions from FEB such as Nirmal province [16] and semi-arid region of Medak [2,37,40].…”

Groundwater is the primary source for drinking uses in the hard rock terrain of central Telangana, India, where most of the people rely on it for daily uses. Therefore, this study was carried out to comprehend the fluoride contamination and its associated health risk assessment to local dwellers. For this study, 54 groundwater samples were collected from bore wells and hand pumps in the study region and were analysed for fluoride and other physicochemical parameters. The results indicated by statistical mean values of Na + , Ca 2+ , Mg 2+ and K + are 182.14, 59.79, 23.90 and 3.74 mg/L, respectively, while HCO 3 2− , Cl − , SO 4 2− and NO 3 − are 236.1, 230.8, 167.7 and 81.9 mg/L, respectively. The fluoride concentration ranged from 0.8 to 4.2 mg/L, with a mean of 2.21 mg/L. Eighty-one percent of the groundwater samples exceeded the World Health Organization's water quality limit of 1.5 mg/L for fluoride. Piper trilinear diagram (PTD) signifies that groundwater quality in the study region is characterized by Na +-Cl − , Ca 2+-Mg 2+-Cl − and Na +-HCO 3 −-Cl − hydrochemical water types. Gibbs diagrams indicate that all the major ion chemistry of the groundwater in the study region is controlled by rockwater interactions, while evaporation plays a minor role. The health risk assessment results revealed that the associated hazard quotient (HQ) for the age range of 6 to 12 months within about 100% of the study area exceeded the acceptable HQ limits of 1. Furthermore, the HQ for age categories 6-11 years, 11-16 years and 16-18 years within 96.2, 68.5 and 50%, respectively, of the study locations were larger than 1. Results also indicate that age group 6 to 12 months was most prone to health risks in the study region. Therefore, in the study region, people should be taken necessary actions to abolish the groundwater contamination to protect the local dweller's health.

“…Human health risk assessments proposed by the United States Environmental Protection Agency (USEPA) [30] are among the most useful approaches for quantifying the degrees of potential risks of groundwater contaminants. This approach has been widely used to evaluate the potential health risks from water contaminants and provide scientific guidance for differential water supplies and cost-effective water treatments [13,[31][32][33][34].…”

Groundwater chemistry and its potential health risks are as important as water availability in arid and semiarid regions. This study was conducted to determine the contamination and associated health threats to various populations in a semiarid basin of north China. A total of 78 groundwater samples were collected from the shallow unconfined aquifers. The results showed that the phreatic water was slightly alkaline, hard fresh water with ions in the order of Ca2+ > Na++K+ > Mg2+ and HCO3− > SO42− > Cl−. Four hydrochemical elements, NO3−, F−, Mn and Zn, exceeded the permissible limits. NO3− and F− contaminants may pose health risks to local residents, while the risks of Mn and Zn are negligible. Dermal exposure is safe for all populations, while the oral pathway is not. Minors (i.e., infants and children) are susceptible to both NO3− and F− contaminants, and adults only to NO3−. The susceptibility of various populations is in the order of infants > children > adult males > adult females. Anthropogenic activities are responsible for the elevated levels of NO3−, Zn, Total dissolved solids (TDS), while F− and Mn are from geogenic sources. Thus, differential water supplies, strict control of waste, and rational irrigation practices are encouraged in the basin.

The present research deals with the quantification of health hazard in a fluorosis prone area from east‐coast of India. The average health hazard quotients are 2.09, 2.42, 1.79, and 1.69 for infants, children, male, and female adults, respectively. These values are more than the tolerance limit (1) in 92% groundwater samples and 96% of the study area. The children are more vulnerable to fluorosis than infants and adults. Ca2+/ Na+ versus HCO3−/Na+ and Ca2+/Na+ versus Mg2+/Na+ plots suggest silicate weathering as the prime factor while linear relationship of TDS versus NO3− + (Cl−/HCO3−) supports the anthropogenic input of F− to the aquifer system. The study suggests that the F− ions are chiefly derived from fluorite, apatite, biotite, and hornblende present in the granitic basement under alkaline environment. The secondary sources are domestic and industrial sewage as well as return flow from irrigation with ingredients of phosphate fertilizers. The adverse effects of fluorosis can be minimized by mass awareness programmes, alternative source of potable drinking water, defluoridation techniques, dilution of high F− concentration in groundwater, and minimizing the use of phosphate fertilizers.
