This work addresses the gap by introducing Quassia indica leaf extract as a bio reductant and stabilizer in the green synthesis of cobalt oxide-zinc oxide nanoparticles (QI: Co<sub>3</sub>O<sub>4</sub>/ZnO NP). The synthesized nanoparticles were characterized using various techniques, including UV-visible spectroscopy, X-ray diffraction (XRD), dynamic light scattering (DLS), high resolution transmission electron microscopy (HR-TEM), selected area electron diffraction (SAED), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (EDX). The existence of hexagonal zinc oxide and cubic cobalt oxide phases in the synthesized nanoparticles was verified by XRD analysis. The elemental composition was confirmed by EDX, which showed that oxygen, zinc, and cobalt were present. The average hydrodynamic diameter of 244.5 d. nm was found via DLS measurements, indicating well dispersed nanoparticles. Under UV light irradiation, photocatalytic activity of QI: Co<sub>3</sub>O<sub>4</sub>/ZnO NP was assessed for the degradation of textile dyes (Reactive Blue-222, Reactive Blue-220, Reactive Red-120, and Reactive Yellow-145). Phytotoxicity tests were conducted to examine the possible environmental impact of the deteriorated dye solution, revealing promising results in mitigating the detrimental impact of industrial dyes. QI: Co<sub>3</sub>O<sub>4</sub>/ZnO NP was also assessed for cytotoxicity studies in DLA and EAC cells which showed a concentration-dependent cytotoxic effect. The research outcomes emphasize the significant potential of these nanoparticles in diverse arena by offering a sustainable and efficacious resolution to the present-day problems.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085629","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 rapid pace of urbanization, coupled with growing population density, exacerbates air pollution levels in major Indian cities, with pollutants such as particulate matter (PM2.5), (PM10), nitrogen dioxide (NO2), nitrogen oxides (NOX), and carbon monoxide (CO) being significantly elevated in comparison with the rural areas. These pollutants have been implicated in the pathogenesis of T2D, by inducing insulin resistance, oxidative stress, and endothelial dysfunction leading to vascular complications of T2D. International studies also highlight a similar association between air pollution and the incidence of T2D. The multifactorial nature of the disease, combined with the myriad of contributing environmental and lifestyle factors, makes it challenging to pinpoint specific risk elements. To mitigate the impact of these combined factors, continuous monitoring of air quality is imperative. Monitoring of traffic emissions, promotion of electric vehicles (EVs), and enhancement of mass transit options can each mitigate the impact of air pollution on type 2 diabetes. Furthermore, the integration of artificial intelligence (AI) and machine learning (ML) can optimize these interventions, making them even more effective. Urban planning strategies focused on increasing green spaces, afforestation, and sustainable construction practices are essential for long term health benefits.

The spatial interpolation of four parameters, particularly electrical conductivity (EC), chemical oxygen demand (COD), chloride, and piezometric levels, is performed via ordinary kriging (OK). The results reveal the presence of high values of EC in the central and northern parts of the aquifer, and that chloride concentrations exceed the recommended irrigation standards in a large portion of the aquifer, mainly due to the presence of excessive industrial discharge. High levels of COD are observed in the northwestern part, probably due to anthropogenic sources.

Understanding how microbial communities respond to such contamination is essential for developing effective bioremediation strategies. Soil samples were collected from the area, designated as BP1 sample selected for detailed metagenomics analysis. The study extracted DNA with a concentration of 46.2 ng/µl, followed by quality checks and profiling to identify microbial communities. Analysis showed that bacterial communities were dominated by Actinobacteria (48.28%) and Proteobacteria (40.80%), while fungi were primarily represented by Ascomycota (89.50%). Among viruses, Negarnaviricota were most prevalent, with the class Insthoviricetes accounting for 94.60%. Diversity analysis indicated that bacterial populations remained stable, fungal diversity fluctuated, and viral diversity increased, reflecting complex ecological interactions. The presence of key genes involved in lipid and carbohydrate metabolism suggests that microbes adapted to contamination by heavy metals and organic pollutants. The dominance of stress-tolerant Proteobacteria and Actinobacteria highlights their potential role in bioremediation.
