The study investigated the influence of nearby soil on the sediments in the reservoir, the accumulation of PTEs in the sediment core layers, and enrichment factors from anthropogenic or natural sources. The methodology focused on the geochemical and physico-chemical characteristics of soils and sediment. The results compose a database with regional interest in the environmental quality of a relevant water supply system for Brazil’s most populous city, as well as to international researchers studying the geochemistry of trace elements in dam reservoir environments. The mean PTEs concentrations, in mg/kg, found in soils and sediments, respectively, were V (116 | 214), Cr (32.7 | 52.8), Ni (7.9 | 13.9), Cu (58 | 65), Zn (61 | 57), Pb (69 | 74), As (5.6 | 25.7), Sb (0.39 | 0.90), and Co (1.97 | 3.40). The study hypothesized arsenic enrichment near sediment core transition zones, with positive correlations between As with Sediment Erosion Flux (SEF), indicating the impact of reservoir flooding on the sediment quality. Signatures of chemical correlation were found between reservoir sediments and catchment soils, which presented signs of copper and lead enhanced by anthropogenic release.</div></div>","PeriodicalId":11716,"journal":{"name":"Environmental Nanotechnology, Monitoring and Management","volume":"23 ","pages":"Article 101070"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data of this study were collected and analyzed in the wet and dry seasons and from a total of 56 groundwater samples. This study used two deterministic and stochastic approaches to evaluate carcinogenic and non-carcinogenic risk. Monte Carlo simulation, which is based on the Markov chain approach, was used for risk assessment. The examination of heavy metals As, B, Cd, Cu, Hg, Mn, Ni, Pb, Sb, V, and Zn in the water samples reveals that except for the arsenic, the insignificant concentration of the abovementioned metals was found, consequently, the health risk studies were conducted focusing on the arsenic contamination. Data analysis revealed the average concentration of arsenic in the dry and wet seasons to be 14.93 ± 17.67 and 13.79 ± 16.57 μg/L, respectively. Furthermore, beyond 39 % and 35 % of the area of Qorveh County rely on groundwater sources having the arsenic contents more than the permissible level (10 µg/L) in dry and wet seasons, respectively. The Monte Carlo simulation output clearly showed that the HQ values ​​for the 95th percentile in the dry season were 3.58 and 2.03 for the age groups of children and adults, respectively. In other words, the non-carcinogenic risk for children is almost twice that of adults. All carcinogenic risk values was reported more than the acceptable threshold, typically set at 1 × 10⁻⁶ (or 1 in a million) by EPA. The sensitivity analysis of the contribution of arsenic concentration, duration of exposure, and rate of ingestion showed 89.5 %, 5.7 %, and 4.6 %, respectively, which indicates the major effect of arsenic concentration.

The nanocomposite was synthesized using hydrothermal method, promoting effective interaction between ZnFe₂O₄, g-C₃N₄, and rGO, which enhances photocatalytic performance. The ZnFe₂O₄/g-C₃N₄/rGO nanocomposite (ZGR NCs) exhibited a 92 % degradation efficiency of IC dye within 60 min, significantly outperforming ZnFe₂O₄ (49 %), ZG (59 %), ZR (64 %), and ZGR without MNB (72 %). The photocatalytic process followed pseudo-first-order kinetics with a high correlation coefficient (R² ∼ 0.9789–0.9968), demonstrating the efficiency of charge separation and transfer facilitated by rGO. ZnFe₂O₄ excels in absorbing visible light, g-C₃N₄ serves as a capable photocatalyst with a suitable bandgap for visible light, and rGO further facilitates electron mobility, minimizing charge recombination. Also, the combination of ZnFe₂O₄, rGO, and g-C₃N₄ generates a synergistic effect that significantly boosts photocatalytic activity. This interaction leads to more effective production of reactive oxygen species, which are essential for degrading pollutants.

Electrochemical analysis conducted via cyclic voltammetry (CV) revealed a marked improvement in electron transfer efficiency and redox behavior compared to unmodified graphene electrodes, attributed to the synergistic interaction among ZnO NR, C-dots, and graphene. The GZC-based electrode demonstrated exceptional sensitivity in detecting fipronil, achieving an impressively low limit of detection (LOD) of 0.00490 µg/L and a limit of quantification (LOQ) of 0.01633 µg/L, outperforming numerous previously reported sensors. A strong linear correlation (R² = 0.9931) was observed between the oxidation peak current and fipronil concentration, indicating excellent analytical performance. Additionally, the sensor exhibited high stability and reproducibility, with a relative standard deviation (RSD) of 0.26 % over 20 consecutive measurements. Validation using a commercial pesticide sample confirmed the sensor’s ability to detect fipronil at trace levels with high accuracy.
