This study highlights the utilization of cobalt-decorated titanium dioxide nanotubes (Co-TNTAs) as robust and efficient sensors for NO_2, addressing the critical need for accurate detection of NO₂ gas with significant environmental and public health implications. In addition, titanium dioxide nanotubes are particularly advantageous in gas sensing due to their facile fabrication, broad availability, and remarkable surface reactivity, which collectively enhance their gas sensing performance. In this work, bare TNTAs were prepared via anodization, followed by electrochemical deposition of cobalt at varying salt concentrations to produce Co-TNTAs. Comprehensive characterization was performed to correlate material properties with sensing behavior: X-ray diffraction (XRD) confirmed phase structure and crystallite size, field emission scanning electron microscopy (FE-SEM) coupled with energy-dispersive X-ray spectroscopy (EDX) revealed morphological and compositional features, and UV–Vis diffuse reflectance spectroscopy (DRS) provided insights into optical absorption and band gap variation. The optimized Co-TNTAs (with 0.2 M cobalt concentration) demonstrated impressive NO₂ sensitivity, reaching 87.43% at 100 ppm NO₂ and an operating temperature of 150°C. Notably, both TNTAs and Co-TNTAs also exhibited excellent response and sensitivity even at ambient temperatures, highlighting their suitability for real-world applications where low temperatures are preferred. These findings highlight the significant role of cobalt modification in enhancing gas sensing functionality and establish Co-TNTAs as promising candidates for next-generation NO₂ sensors that combine high sensitivity, low operating temperature, and structural tunability.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 14","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 review paper explores the various aspects of soil pollution in urban areas, including its sources, types of pollutants, consequences, mitigation strategies, and the importance of sustainable urban development. The sources of soil pollution in urban environments are diverse, ranging from industrial activities and waste disposal to emerging sources like microplastics and pharmaceuticals. The types of pollutants found in urban soils include heavy metals, polycyclic aromatic hydrocarbons (PAHs), and organochlorine pesticides, among others. The consequences of soil pollution in urban areas encompass public health risks, environmental impacts, and contamination of water resources. Mitigation strategies such as remediation techniques, pollution prevention measures, urban green infrastructure, and public awareness are crucial for addressing soil pollution in urban environments. Sustainable urban development plays a key role in maintaining soil health and integrating soil considerations into urban planning.

Bioremediation has emerged as an ecologically sustainable and effective strategy for breaking down MPs; however, understanding the processes and mechanisms underlying the biodegradation of MPs remains limited. The present review highlights the diversity study of potential bacteria, fungi, and actinomycetes in mangrove environments. The potential of bacteria, fungi, and algae in the MPs biodegradation is highlighted with particular attention paid to the effects of MPs characteristics, microbial activity, environmental factors, and chemical interactions on degradation efficacy. The processes of biological degradation, such as colonization, fragmentation, assimilation, and mineralization, are covered in detail. Furthermore, the toxicological impacts of MPs on both human and microbial populations, the challenges that microbial colonization presents for MPs, and the ability of microorganisms to break down MPs are also discussed. This study evaluates biodegradation technology’s potential and current constraints in addressing MPs pollution.

Taxonomic studies of the isolated strain revealed that it was <i>Escherichia</i> sp. PP001 (GenBank: KP770133.1), and it has the potential to degrade azo dyes. The culture conditions were optimized under various physiological parameters such as dye concentrations, pH, temperature, and agitation.

Biosorption kinetics fit pseudo-zero-order and diffusion models, indicating surface adsorption and intraparticle diffusion. GC–MS (Gas Chromatography Mass Spectroscopy) analysis elucidated metabolite degradation pathways. Physicochemical properties of the treated and untreated textile effluent were examined and compared.

Among the various methods available for decontaminating textile effluents, adsorption has proven to be particularly effective. This study investigates the use of Mimosa caesalpiniifolia wood powder as a biosorbent for the removal of methylene blue (MB) dye from aqueous solutions. The wood powder underwent both hot and cold extraction processes to remove extractives. The biosorbent was characterized using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Zero Charge Potential (ZPC) analysis. Subsequently, experiments were conducted to study dye degradation, the effects of pH, adsorption kinetics, and adsorption isotherms. The pH tests revealed that the highest MB dye adsorption occurred in alkaline conditions. The kinetic study determined an equilibrium time of 120 min with a dye removal efficiency of 96.98% ± 0.052%. Among the kinetic models tested, the pseudo-second-order model provided the best fit, with a Maximum adsorption capacity of 12.140 mg·g⁻¹. Regarding the isothermal models, the Langmuir model showed the best fit, with Maximum adsorption capacities of 39.623, 42.189, and 43.783 mg·g⁻¹ at temperatures of 28 °C, 38 °C, and 48 °C, respectively.

Over half of global population lacks access to safe drinking water and the situation is projected to worsen in near future. This has necessitated the development of advanced wastewater treatment systems capable of producing high-quality effluent. In present scenario an economical, and ecologically safe material for environmental remediation is warranted. The present study addresses the synthesis of SiO₂ NPs from <i>Hibiscus rosa sinensis</i> flower extract for wastewater treatment. The presence of siloxane and Si–O bonds was affirmed from FTIR spectroscopy. A band gap of 3.02 eV was estimated for the NPs from the Tauc plot. The NPs constituted an average particle size of 19.9 nm with a zeta potential of –49 mV. Photocatalytic efficacy of SiO₂ NPs was investigated for individual dyes namely methyl orange, eosin yellow and methylene blue and their ternary mixture under sunlight. The NPs were remarkable photocatalyst for degradation of textile dyes and exhibited good stability till the fourth cycle of reuse. Furthermore, the SiO₂ NPs-loaded cotton fabric exhibited excellent photocatalytic performance in terms of removal of 90% of dye, thereby validating its efficacy towards development of self-cleaning fabrics. The efficacy of the green NPs as a nanofertilizer was examined for okra seeds and NPs concentration upto 100 mg/ L stimulated the shoot elongation without any adverse impact. The ecotoxicological impact of photodegraded dye solution on growth of okra seeds indicated no inhibitory phytotoxic effect. Thus, the green synthesized SiO₂ NPs using red hibiscus flower extract are sustainable photocatalysts for degradation of anthropogenic organic pollutants and design of smart textiles. Furthermore, the ecological safety assessment asserted the potential use of photodegraded water for sustainable agriculture.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 14","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
