This study addresses a significant research gap by focusing on the hydro-geochemical composition and contamination of groundwater in the Kathmandu Valley, an area with limited detailed assessments. The novelty of this work lies in its comprehensive analysis of both shallow and deep groundwater, particularly concerning the high concentration of contaminants like arsenic, microbial pathogens, and ammonium, which are critical for public health. The results indicate that the mean concentration of turbidity, iron (Fe), and total coliform (TC) was exceeded the permissible range by National Drinking Water Quality Standards (NDWQS). Hydro-geochemical analysis using the Piper and Chadha diagrams showed the Ca²⁺-Mg²⁺-HCO₃ dominance, suggesting carbonate rock weathering and ion exchange as primary processes. Gibbs and mixing diagrams further supported these findings. The Water Quality Index ranged from 3.93 to 442.11 (mean: 66.87) for shallow water while 8.07 to 252.87 (mean: 79.24) with turbidity, iron, and ammonia significantly contributing to the overall index. Salinity hazard assessment considering total dissolved solids, sodium adsorption ratio, sodium percentage, magnesium adsorption ratio, and Kelly ratios, indicated that shallow and deep groundwater samples are suitable for irrigation, as confirmed by Wilcox diagrams. This study provides valuable insights into the groundwater quality of Kathmandu Valley and highlights the need for effective management strategies to ensure sustainable use of this vital resource, providing a nuanced understanding of groundwater quality and its implications for water management in the region. The findings can inform water treatment practices, policy-making, and future research, ultimately aiding in the development of safer and more sustainable groundwater management practices for the region.</p>","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 3","pages":"61"},"PeriodicalIF":3.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143051953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three (3) NORMs (⁴⁰ K, ²³⁸U, ^{and 232}Th) were assessed using gamma spectrometer with a NaI detector while ten (10) PTEs (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined by digestion method using Inductively coupled plasma optical emission spectrophotometer. The FCA was used to evaluate soil contamination, and SPSS version 21.0 was used for statistical analysis. Concentration range of PTEs(mg/kg) and NORMs(Bq/kg) in all the site are: As (5.62 ± 0.85 - 15.93 ± 2.40), Cd (BDL-1.26 ± 0.60), Co (5.56 ± 1.34 - 27.25 ± 1.14), Cr (18.68 ± 1.54 -61.43 ± 6.33), Cu (12.40 ± 1.31-82.43 ± 7.94), Fe (15,035.00 ± 81.12 - 36,520.00 ± 292.20), Mn (168.97 ± 5.93 - 353.30 ± 20.84), Ni (5.63 ± 1.99- 25.54 ± 2.50),),Pb (4.44 ± 0.8 - 17.87 ± 2.80) and Zn (42.97 ± 413 - 147.00 ± 7.50); ⁴⁰ K (76.78 ± 44.76-2647.88 ± 179.44), ²³⁸U (3.24 ± 1.82-55.42 ± 24.88),and ²³²Th (5.24 ± 3.90-244.36 ± 89.84).

Using the analysis results, indexes such as Water Quality Index and Heavy Metal Pollution Index were calculated. The results show that the lake water complies with TS 266 and WHO standards. The index results indicate that the lake water is at low pollution and risk level and is safe. The distribution and sources of heavy metals were examined using correlation analysis, Principal Component Analysis and Hierarchical Cluster Analysis. Correlation analyses showed that there were significant relationships between pH, temperature, conductivity, dissolved oxygen and TDS and heavy metals. PCA results revealed that Zn was positively correlated with temperature and pH, while Mn and Ni were inversely correlated. The alignment of Pb, Cu and Cd in the same direction showed that these parameters were affected by common sources. HCA results showed that Cr and Fe have similar transport and source properties, while Mn and Ni are affected by different sources.

However, the mechanisms affecting the adsorption of organic pollutants in the presence of metal ions remain poorly understood due to limited molecular-level studies. This study investigated the adsorption behavior of sulfamethoxazole (SMX) on montmorillonite (MT) at different pH values (1.6, 3.0, and 5.0) in the presence of three metal cations with different valences: Na⁺, Ca²⁺, and Cr³⁺. At pH 5.0, the adsorption of SMX by MT at pH 5.0 in Ca²⁺ and Cr³⁺ systems increased significantly-by 7.25 times and 47 times, respectively, compared to those at pH 1.6. In contrast, Na⁺ had a less pronounced effect on SMX adsorption. Density functional theory (DFT) calculations indicated that as the pH value increases, the interaction between SMX, metal ions, and MT strengthens. Furthermore, the adsorption binding energy of SMX in the high-valence Cr³⁺ system (- 94.51 kcal/mol) was significantly lower than in the low-valence Na⁺ system (- 36.55 kcal/mol). As pH and cation valency increased, the bonding density of cation bridges also increased, leading to a more substantial enhancement in SMX adsorption.

This understanding is essential for the rational and efficient utilization of Se resources, the maintenance of ecological balance, and the preservation of human health in the future. Through a comprehensive literature search, relevant studies were identified, and information regarding soil total Se content, soil available Se content, soil pH, and soil organic matter (SOM) was extracted. The Mann-Kendall (M-K) test was employed to analyze the variation of total soil Se content, while Moran's I was used to examine the global and local spatial clustering characteristics of soil Se. The results indicate that the total Se content in China has shown an increase at different spatial and temporal scales, particularly in Central China. Furthermore, there is a significant difference in total Se content between cultivated soil and natural soil in Central China (P < 0.05). Additionally, soil physicochemical properties have been found to impact soil total Se content. Specifically, pH is negatively correlated with soil total Se content, while SOM is positively correlated with it (P < 0.05). Overall, the findings suggest that the total Se content in Chinese soil is increasing over time, and human agricultural activities and physicochemical properties of the soil, such as soil pH and SOM, likely influence the bioavailability of Se or the overall soil total Se content through their interaction with Se speciation in the soil to some extent.
