We estimated the risks of consuming these products by calculating the Hazard Quotient (HQ), Hazard Index (HI), and Total Hazard Index (THI). Our results showed that the Cd, Cr, Cu, Ni, and Pb concentrations in all edible parts of the plants exceeded the threshold values in all the crops studied (cocoa beans, banana fruits, and cassava rhizomes). In addition, there was a possible non-carcinogenic risk associated with the consumption of banana fruits by children (THI > 1). For adults, there was no probable risk of consuming the products from the studied plants (HQ, HI, and THI < 1). In conclusion, the association between PTEs and Fe oxides, which often act to reduce PTEs' phytoavailability, was not an efficient mechanism in the studied area. This inefficiency raises concerns regarding the risk associated with food production in such environments.","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 11","pages":"473"},"PeriodicalIF":3.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145198783","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}

This research aimed to characterize geophagic soils based on their geochemical and mineralogical properties and to assess the potential human health risks associated with exposure via multiple pathways. Samples from six geophagic hotspots were analysed for macro elements (K, Ca, Mg, and P), microelements (Cu, Cr, Ni, Fe, Zn), and potentially toxic elements (PTEs) (As, Pb, Cd, Hg). Geochemical ratios from the United States Environmental Protection Agency (USEPA) were used to compute human health risk indices (HRIs), including carcinogenic risk (CR) and non-carcinogenic risks (hazard quotient (HQ) and hazard index (HI)). Mineralogy of the clay-sized fractions indicates the presence of kaolinite, goethite, illite, calcite, and muscovite. The average concentrations of macro elements followed the order: K (1.43%) > Ca (0.88%) > Mg (0.47%) > P (0.012%), while the average contents for microelements were Fe > Cu > Cr > Ni > Zn, and PTEs ranged as follows: Pb > As > Hg > Cd with Pb having a mean concentration of 15.16 mg kg-1 and As 1.92 mg kg-1 respectively. The HIs of the PTEs for all three exposure pathways are below 1 for both adults and children. Ni, Cr, and As have the highest mean CR values, which fall within the acceptable range of 1.00E-06 to 1.00E-04 for both adults and children for exposure through oral consumption and dermal contact, while the mean CR values for exposure through inhalation are all below 1.00E-06. Thus, exposure to PTEs in the soil is unlikely to pose health risks. Nevertheless, caution is necessary as cumulative exposure from other sources could significantly increase the overall health risk to practitioners.","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 11","pages":"471"},"PeriodicalIF":3.8,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145198794","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}

Recently, mycogenic metal oxide nanoparticles considered a novel frontier in remediation technologies, addressing the failure of conventional methods to mitigate water pollution. The current study investigates the mycosynthesis of copper oxide nanoparticles (CuO NPs) using Metarhizium anisopliae, Beauveria bassiana and Serendipita indica and evaluates their potential for wastewater remediation. Among the three, Serendipita indica-mediated CuO NPs exhibited superior properties, including a hydrodynamic size of 179.1 nm, high elemental purity (95.66% Cu via EDX) and average particle sizes of 75 nm (SEM) and 49.2 nm (TEM). XPS confirmed pure CuO NPs with Cu 2p at ~ 933 eV and O 1 s at ~ 530 eV. The BET surface area of 8.28 m2/g and mesoporous structure (~ 21.7 nm), with good thermal stability by TGA (0.084% weight loss up to 800 °C) and DSC analysis. Remediation using CuO NPs (100 mg/L) on water samples from Wazirabad, Ghazipur and Okhla Barrage revealed substantial reductions in physicochemical parameters, particularly at Wazirabad: pH (33.63%), TDS (42.58%), TSS (50.59%), BOD (54.69%), COD (46.25%) and turbidity (58.82%). Interestingly, the toxic metals, including arsenic, lead, iron and cadmium were reduced by 74.19%, 66.66%, 40.25% and 40.25%, respectively. One-way ANOVA confirmed statistically significant reductions in all four trace metals (df = 4, F = 9.973, p < 0.01). Tukey's post-hoc test revealed significant removal of arsenic and lead compared to iron (p < 0.01). These findings underscore the efficacy of S. indica-derived mycogenic CuO NPs as eco-friendly agents for wastewater remediation.","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 11","pages":"467"},"PeriodicalIF":3.8,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145191369","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}

The crystalline substances in RCD include KCl, Fe2O3, SiO2, ZnO, and Zn4Si2O7(OH)2(H2O), while the organic matter is mainly aromatic compounds with low concentration. The overall order of heavy metal (HM) concentration in RCD is as follows: Zn > Pb > Cr > Ni > Cd > As > Cu > Hg. The results of the improvement of Community Bureau of Reference (BCR) sequential extraction showed that Hg, As, Cd, Cr, Cu, Ni, and Zn in RCD were mainly in the residual fraction. The leaching concentrations of HMs in RCD were far below the identification standards for hazardous waste. Referring to the control limit requirements of HMs (GB 15618-2018), the geological accumulation index (Igeo) of Cd reached 5.27. Meanwhile, the potential ecological hazard coefficient (Er) values of Hg and Cd were 44.48 and 1740.00, respectively, and the comprehensive potential ecological risk index (RI) value for HMs was 1826.27. This indicated that the ecological risk of HMs in RCD is extremely high and it cannot be used as agricultural land soil. However, the Igeo (< 0), Er (< 40) and RI (< 150) of HMs of RCD as development land soil were lower, and its ecological risk was slight. RCD had no significant effect on the histopathological changes of mice. The rational use of RCD in production will not cause obvious toxic effects on target animals. Based on risk assessment and safety evaluation, the resource utilization of RCD is controllable, safe and reliable.","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 11","pages":"466"},"PeriodicalIF":3.8,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145191349","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}

The PMF model ascertained five sources of HMs: coal combustion and smelting activities, welding and plating sources, transportation emissions, agricultural sources, and general industry sources. Overall, the study region exhibited mild to moderate ecological risk, primarily driven by coal combustion, smelting activities, and general industry, which should be prioritized for control.
