Coal mining may cause considerable environmental problems (Gomo and Vermeulen 2014) including the excessive decline in the elevation of the water table, the drying up of springs near mine sites, the reduction of river levels, and the contamination of groundwater and nearby surface water bodies (Howladar et al. 2017).Consequently, coal …

Spatiotemporal variations in soil water content (SWC) and soil water stable isotopic compositions (SWSIC; 2 H/ 1 H (δD) and 18 O/ 16 O (δ 18 O)) provide critical information on elucidating land surface processes across scales. Meanwhile, little is known about the spatiotemporal characteristics of SWSIC and its driving factors. Therefore, it's …

Future studies, ideally using multi-isotope approaches combined with element isotope mass balances and modeling/assessment of potential post-release fractionation, are expected to confirm the promise offered by stable isotope systems in source identification as well as to provide more precise and accurate estimates of the fate of …

Stable isotopes in water of oxygen (16 O and 18 O) and hydrogen (1 H and 2 H) are typically inert and conservative in mixing relationships and used as a tracer to investigate hydrogeological and hydrological processes including groundwater recharge and groundwater–surface-water interaction [14,15].Accordingly, the deuterium excess (D ex) …

Hydrogen and oxygen stable isotopes (2 H/ 1 H and 18 O/ 16 O), as components of water molecules, are a particular category of environmental tracer. Variations in isotopic abundances can be used to infer water environmental processes such as recharge, flow path, discharge and evaporation ( Chang et al., 2020, Hu et al., 2020, Liu et al., 2022 ...

Lithium and Boron isotope are number of the "non-traditional stable isotopes", which have become one of the most popular fields and frontiers of isotope geochemistry in recent years (He et al., 2020). large mass differences between Li isotopes and B isotopes lead to large isotope fractionation during geological processes …
