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.

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).

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 (I_geo) of Cd reached 5.27. Meanwhile, the potential ecological hazard coefficient (E_r) 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 I_geo (< 0), E_r (< 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.

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.

This study investigates the efficacy of readily available, low-cost raw adsorbents-specifically biochar, Fly ash, and bagasse ash-for the removal of heavy metal ions (Cr, Cu, Fe & Zn) from municipal landfill leachate. The influence of pH, dosage, and contact time on adsorption efficiency was determined through batch experiments. To determine the best-fitting kinetic model (Pseudo-First-Order-PFO, or Pseudo-Second-Order-PSO, Webber & Morris Intraparticle diffusion or Elovich), four error functions- the sum of the square of the errors (ERRSQ), the hybrid fractional error function (HYBRID), average relative error deviation (ARE), and the sum of the absolute errors (EABS)- were calculated and subsequently normalized using the Set of Normalized Errors (SNE) method. The kinetic model with the lowest SNE value was found to provide the best statistical fit to the experimental data. Adsorption kinetics for biochar showed PFO for Cr, Cu, and Zn, and PSO for Fe. Fly ash followed PFO for Fe and Zn, and PSO for Cr and Cu. Bagasse ash kinetics showed PFO for Cr and PSO for Cu, Fe, and Zn. The maximum adsorption removal efficiencies for Cr, Cu, Fe, and Zn obtained were 82%,54%, 72% & 62% for biochar, 77%, 50%, 62%, 64% for Fly ash, and 87%, 42%, 79%, 72% for bagasse ash. These findings demonstrate that low-cost, waste-derived adsorbents can effectively remove heavy metals from complex solutions, such as landfill leachate, with high efficiency.

The results reveals that Ni (3%) and Pb (4%) exceeded World Health Organization (WHO) permissible limits, and Al (16%), Mn (3%), Ni (5%), Pb (4%) and Fe (42%) of samples exceeding Bureau of Indian Standards (BIS) acceptable limits. Spatial distribution of metals shows that there is a higher concentration towards Delhi area and the Southern parts of the study area.
