“…The Triassic aquifer sample j.v. 2391-1 had a higher 3 H value (4.17 TU) and a more positive δ 18 O value, while the remaining samples had low 3 H values (around 0.05 TU). Kanduč et al [46] recorded 3 H values of 3.7 to 6.4 TU for the groundwater using the enrichment method.…”

“…The sample was then vacuum-degassed (> 99.9995%) and sealed using a metal pinch clamp. After 60 days, the in-grown 3 He was passed through the purification system where it was trapped on charcoal at 10 °K. The 3 He was then desorbed and introduced into a large-radius sector-field mass spectrometer (Helix SFT) and quantified using peak height manometry.…”

“…For example, some degassing sites at the SE Austria/NE Slovenia border, less than 50 km from the Velenje coal basin, show a helium isotope signature typical for the subcontinental lithospheric mantle (SCLM). In CO 2 -dominant gas emissions (mofettes) and in the sites with the highest 3 He contributions (up to 6.3 Ra, where Ra is the 3 He/ 4 He in atmospheric gas), δ 13 C CO2 values are around − 3.5‰ [68].…”

“…Trace element (Fe, Mn, Co, As, Cu, Cr, Pb, Zn, Ni, etc.) concentrations and stable isotope compositions (e.g., δ 13 C CO2 , δ 18 O, δ 2 Η, δ 34 S SO4 , δ 18 O SO4 ) of groundwater depend on multiple natural factors including the aquifer lithology, the quality of the infiltrating water, mineral weathering reactions, groundwater residence time and mixing of groundwater bodies [1][2][3][4][5][6]. Anthropogenic sources of trace elements include infiltration from contaminated soils, leaching from industrial effluents and the dumping of sewage sludge [6].…”

This study investigated the mineralogical and isotopic composition of groundwater and precipitation to identify and constrain geochemical processes within stacked Pliocene and Triassic aquifers in the Velenje coal basin. Scanning electron microscopy combined with energy-dispersive X-ray spectroscopic analysis revealed that suspended matter in the Pliocene aquifer consists of feldspars and quartz, while dolomite, calcite and feldspars are present in the aquifer dewatering Triassic strata. The concentrations of trace elements in Triassic and Pliocene aquifers range from highest to lowest Zn > Fe > Ni > Al > Ba > Mn > B>Li > Mo > As with the majority of trace element concentrations below international drinking water health guidelines. Multivariate principal component analysis indicated that concentrations of Mn, Ba, Eu, Cs, Y, Li and T, pH, conductivity and dissolved oxygen in samples were the best chemical parameter for distinguishing the two aquifers. A significant positive correlation (p < 0.05) was found between Ni, Mn, Co, Zn, As and Mo. Groundwater in the Pliocene aquifer likely has an external source of carbon based on the δ 13 C CO2 values (− 12.3 to − 3.6‰). The groundwater also has detectable levels of dissolved methane with isotopic values (− 77.7 to − 51.4‰ δ 13 C CH4 ; − 247 to − 162‰ δ 2 H CH4) consistent with microbial methanogenesis. The groundwater in the Triassic aquifer has tritium values (up to 4.1 TU 3 H) characteristic of modern recharge (< 50 years), while the lack of detectable 3 H (0 TU) in the Pliocene aquifer is consistent with longer residence times.

“…Hydrogen and oxygen isotopic fractionation processes have been widely used in water source analysis and water cycle study. The isotope composition of water changes along with physicochemical processes, such as evaporation and water-rock interactions [30]. The δ 18 O (H 2 O) values and δ 2 H values of these water samples were plotted in Fig.…”

Antimony (Sb) is a versatile metal element and has found applications in flame retardants, batteries, solar cells, and semiconductor industries. The increasingly widespread usage of Sb has caused environmental pollution. Recently, Sb has been detected in soil, water, river sediment, plants, and groundwater-especially in areas around Sb mines [1]. The Xikuangshan Mine in Hunan, China, known as the world's antimony capital [2], currently accounts for 90% of the world's total antimony ore production [3]. Numerous studies have been carried out in this area to evaluate the multimedia environmental pollution caused by Sb [4-6]. The Qingfeng and Xuanshan rivers, two main tributaries of the Zijiang River, have already been heavily polluted
