“…This categorization can be accredited to mineral solubilization, rock/water interaction, and ion exchange processes. Our findings are supported by [ 1 , 7 ], who observed a higher F − concentration associated with the NaHCO 3 and mixed CaNaHCO 3 water types in the underlying geological environment. With respect to cations, all of the samples were of the Zone D sodium type, which indicates the significance of silicate weathering, while the anions all of the samples were of the Zone E bicarbonate type, indicating the eminence of carbonate weathering in the study area [ 24 ].…”

“…F − enrichment can be found in a variety of habitats, including GW, soil, rocks, food, air, flora, fauna, and the human body [ 6 ]. GW is a key source of F − for human ingestion, possibly recognized and controlled by hydrogeology, climatic factors, anthropogenic actions, and the regional chemistry of the host rocks [ 7 ]. Soil contains 0.3 g/kg F − content in Earth’s crust in terms of natural abundance, and it is the 13th most important source [ 8 ].…”

Fluoride (F−) contamination in drinking groundwater is a significant human health risk in Pakistan. Moreover, high fluoride pollution in drinking water causes a variety of disorders, including dental, neurological, and skeletal fluorosis. The aim of this research was to evaluate the health risk of elevated fluoride in groundwater and its suitability assessment for drinking purposes. The total of (n = 37) samples were collected from community tube wells of Quetta Valley, Balochistan, Pakistan. The results show a mean pH value of 7.7, TDS of 404.6 mg/L, EC of 500 µs/cm, depth of 96.8 feet, and turbidity of 1.7 nephelometric turbidity units. The mean values of HCO3−, Ca2+, Mg2+, and Na+, were 289.5, 47.5, 30.6, and 283.3 mg/L, respectively. The mean values of SO42−, NO3−, K+, Cl−, and Fe2+, were 34.9, 1.0, 1.6, 25.6, and 0.01 mg/L, respectively. The F− concentration in the groundwater varied between 0.19 and 6.21, with a mean value of 1.8 mg/L, and 18 samples out of 37 were beyond the WHO recommended limit of 1.5 mg/L. The hydrochemical analysis results indicated that among the groundwater samples of the study area, 54% samples were Na-HCO3 type and 46% were mixed CaNaHCO3 type. The saturation indices of the mineral phases reveal that the groundwater sources of the study area were saturated with CaCO3 and halide minerals due to their positive (SI) values. Such minerals include calcite, dolomite, gypsum, and fluorite. The principal component analysis results reveal that the groundwater sources of the study area are contaminated due to geological and anthropogenic actions. The health risk assessment results of the F− concentrations show the ranges of ADDingestion for children, females, and males in the Quetta Valley, and their mean values were observed to be 0.093052, 0.068825, and 0.065071, respectively. The HQingestion mean values were 1.55086, 1.147089, and 1.084521 for children, females, and males, respectively. It was noticed that children had the highest maximum and average values of ADDingestion and HQingestion in the research area, indicating that groundwater fluoride intake poses the greatest health risk to children. The water quality index (WQI) analyses show that 44% of the samples belong to the poor-quality category, 49% were of good quality, and 8% of the samples of the study area belong to the excellent category.

This review covers the preparation, characterization, and application of magnetic adsorbents obtained from carbon-based sources and their application in the adsorption of both inorganic and organic pollutants from water. Different preparation routes to obtain magnetic adsorbents from activated carbon, biochar, hydrochar, graphene, carbon dots, carbon nanotubes, and carbon nanocages, including the magnetic phase incorporated on the solid surface, are described and discussed. The performance of these adsorbents is analyzed for the removal of fluoride, arsenic, heavy metals, dyes, pesticides, pharmaceuticals, and other emerging and relevant water pollutants. Properties of these adsorbents and the corresponding adsorption mechanisms have been included in this review. Overall, this type of magnetic adsorbents offers an alternative for facing the operational problems associated to adsorption process in water treatment. However, some gaps have been identified in the proper physicochemical characterization of these adsorbents, the development of green and low-cost preparation methods for their industrial production and commercialization, the regeneration and final disposal of spent adsorbents, and their application in the multicomponent adsorption of water pollutants.

The Tibetan Plateau (TP) is known as the “Asian Water Tower” and provides vital drinking water for residents of China and Southeast Asian countries. However, large-scale regional research on water quality in this climate-sensitive and eco-fragile area is still lacking. Considering that drinking from fluoride-contaminated water has posed serious health concerns worldwide, especially in Asian counties, it is urgent to clarify the spatial-temporal distribution characteristics, influencing factors, and health risk of fluoride in surface water in the TP. In this study, a total of 2697 surface water samples from major rivers and typical lakes in the TP were systematically analysed. Overall, fluoride concentrations ranged from 0.005 mg L−1 to 6.240 mg L−1 and varied among water periods, water basins and even water types. Pearson’s correlation analysis showed that the distribution of fluoride concentration was closely related to regional climate and positively correlated with anthropogenic activities. Probabilistic health risk assessment revealed that potential hazards in the Inner basin remained highest for all age groups (HR>1), especially for infants and adults (HR>3), while the risks in most other water basins were acceptable (HR < 1). In addition, more than 75% of the residents affected by the surface water in the TP were assessed as having a low fluoride exposure health risk. Our findings can provide scientific support for fluorosis prevention, as well as guide water resource utilization in the TP and adjacent region.
