“…7, the shallow groundwater samples before ecological restoration fell between the dominant fields of rock weathering and evaporation/ concentration, indicating that the water-rock interactions of the shallow groundwater before ecological restoration were controlled by rock weathering and evaporation/ concentration processes. Approximately 69.23% of the shallow groundwater samples after ecological restoration were located in the dominant field of rock weathering, indicating that the water-rock interaction after ecological restoration was mainly affected by rock weathering, which was consistent with the results of Hao et al [36].…”

“…Before and after the ecological restoration, some water samples had Sb/SO 4 2molar ratios between 0.0008 and 0.016 (Fig. 5a), which were significantly lower than those of Sb/SO 4 2dissolved by the oxidation of Sb 2 S 3 , indicating that these water samples may have the same source of Sb/SO 4 2- [36]. As the primary source mineral of Sb, Sb 2 S 3 dissolves in water.…”

The ecological restoration project of Xikuangshan (XKS) effectively reduces environmental pollution. However, the hydrogeochemical factors and mechanisms leading to the evolution of antimony (Sb) content in shallow groundwater after ecological restoration have not been studied. In order to investigate the geochemical evolution of Sb content in shallow groundwater, 64 samples were collected before and after the ecological restoration project. The results showed Sb concentrations in shallow groundwater before and after ecological restoration were 0.006-39.160 mg/L (mean 3.501 mg/L), and 0.003-17.326 mg/L (mean 2.931 mg/L), respectively. The high Sb content before ecological restoration was mainly caused by the oxidation of Sb 2 S 3 , dissolution of carbonate and silicate minerals, evaporation/concentration effects, and cation exchange. The weaker oxidation of Sb 2 S 3 and effective cleaning of the arsenic alkali residue reduced the Sb content in shallow groundwater after ecological restoration. This study provides a basis for understanding the effects of ecological restoration projects on the evolution of Sb content in shallow groundwater, and provides a new idea for solving groundwater pollution and promoting groundwater resources management.

“…Previous studies have found that geogenic processes are frequently responsible for elevated Fconcentrations in groundwater (Dehbandi et al, 2018;Emenike et al, 2018;Rashid et al, 2018;Hao et al, 2021c;Duggal and Sharma, 2022;Huang et al, 2022). Importantly, F-bearing minerals in rock strata, including fluorite, fluorapatite, and cryolite, are typically identified as the most important geogenic sources of F - (He J et al, 2013;Mondal et al, 2014;Olaka et al, 2016;Laxmankumar et al, 2019;Hao et al, 2021d;Duggal and Sharma, 2022;Rehman et al, 2022). In addition, specific water-rock interactions play a very important role in the fluoride enrichment of groundwater, such as evaporation (Dehbandi et al, 2018;Li et al, 2018;Chicas et al, 2022;Rehman et al, 2022), competitive adsorption (Li et al, 2018;Ali et al, 2019;Rehman et al, 2022), and ion exchange effects (Li et al, 2015;Ali et al, 2018;Huang et al, 2022;Nizam et al, 2022).…”

“…Atmospheric precipitation, evaporation, and rock weathering can reflect hydrogeochemical processes in Gibbs diagrams. All high-Fdeep groundwater samples from both the dry and wet seasons fell under rock weathering and evaporation dominance with medium to high TDS, high Na/(Na+Ca) and low Cl/(Cl+HCO 3 ) ratios (Supplementary Figure S2), indicating that the rock weathering and evaporation processes were dominant geochemical factors for increasing the Fcontent in deep groundwater (Dehbandi et al, 2018;LaFayette et al, 2020;Hao et al, 2021d).…”

High-fluoride (F-) deep groundwater in the vicinity of mining areas poses severe ecological risks. In this study, we aimed to characterize and reveal the seasonal distribution and influencing factors of elevated F- concentrations in the deep groundwater in the Shendong mining area, Shaanxi and Inner Mongolia province, China. In addition, the ecological risks associated with F- concentrations in irrigation water were assessed. During the wet and dry seasons, the F- concentrations in mine water samples ranged between 0.12 and 13.92 mg/L (mean: 4.24 mg/L) and between 0.20 and 17.58 mg/L (mean: 4.59 mg/L), respectively. The F- content of mine water was clearly higher during the dry season than that during the wet season. F- concentrations in deep groundwater exhibited consistent spatial distributions during both the dry and wet seasons, with an evident increase from southeast to northwest. The dissolution and precipitation of F--bearing and calcium minerals, cation exchange, competitive adsorption, evaporation, and anthropogenic activities during both the wet and dry seasons were identified as important factors influencing F- concentrations in deep groundwater. In addition, the ecological assessment revealed that 100% and 88.89% of low-F- deep groundwater samples were suitable for practices during the dry and wet seasons, respectively. In contrast 84.00% and 84.62% of high-F- deep groundwater samples were unsuitable for irrigation practices during the dry and wet seasons, respectively. This research provided useful prevention policies of deep groundwater extraction to mitigate environment problems associated with excessive F- irrigation.
