The photocatalytic activity of the nanowires was then evaluated through the reduction of hexavalent chromium (Cr(VI)) to trivalent chromium (Cr(III)). Rapid Cr(VI) reduction was observed for CuO nanowires formed at 500 °C, attributed to the higher nanowires’ density at this temperature.

This study presents the first comprehensive assessment of cigarette butt litter on terrestrial urban streets in Tubod, Iligan City, Philippines. Field observations were conducted from October to November 2022, between 12:00 and 5:00 p.m. Philippine Standard Time, using a modified visual survey method adapted to local conditions. A total of 11,306 cigarette butts were collected across all 41 surveyed sites, corresponding to a mean litter density of 0.083 ± 0.090 items per square meter. The street area exhibited only a modest explanatory effect on cigarette butt accumulation at the pooled level (coefficient of determination = 0.38), with residual diagnostics indicating heteroscedasticity and non-normality. Disaggregated analyses revealed that residential streets showed a statistically significant relationship, whereas commercial, institutional, and mixed-use streets exhibited weak relationships. Fourier transform infrared spectroscopy confirmed that cigarette filters are composed of cellulose triacetate, a durable polymer with long environmental persistence. The spatial distribution patterns indicate a predominantly linear consumption-to-disposal pathway, with filters discarded directly at points of use. Accordingly, the study proposes context-specific mitigation measures, including optimized placement of butt-specific receptacles in high-activity streets, targeted enforcement of anti-littering ordinances, and pilot-scale recovery integrated into municipal and informal waste systems. Future multi-index frameworks that combine chemical characterization, spatial metrics, and human activity indicators are recommended to better resolve accumulation dynamics and identify gaps in urban waste management.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 5","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606988","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}

The primary aim was to evaluate the radiological hazards associated with these samples. The activity concentrations of the radionuclides were comparable to those reported in the literature but occasionally exceeded the global safety limits set by UNSCEAR. The Pearson correlation coefficients for ²³⁸U and I_γr were notably high (0.58 for Al-Nasiriyah and 0.87 for Al-Musaaeb), which is consistent with previous studies. The study calculated the annual effective dose (AEDE) to be between 0.44 and 1.3 mSv/y (average 0.71 mSv/y) for Al-Musaaeb, and 0.29–0.53 mSv/y (average 0.40 mSv/y) for Al-Nasiriyah. The excess lifetime cancer risk (ELCR) values ranged from 1.53 to 4.55 nGy/h (average 2.49 nGy/h) for Al-Musaaeb and 1.00–1.85 nGy/h (average 1.39 nGy/h) for Al-Nasiriyah. Radiological hazard assessments indicated that most indexes were within acceptable global reference levels, suggesting no significant radiological threat from the samples. Therefore, fly ash can be safely used in various applications.

Despite extensive research on carbonaceous materials in advanced oxidation processes, challenges such as low activation efficiency and limited reusability hinder their large-scale application. Therefore, a deeper understanding of the catalytic mechanisms of non-metallic carbon materials in advanced oxidation processes is crucial for optimizing their performance. In this study, nitrogen-doped carbon nanotubes are investigated as effective activators of periodate for the degradation of sulfisoxazole which is a sulfonamide antibiotic and a potential carcinogenic frequently detected in wastewater. Experimental results of this study demonstrated that under optimized conditions nitrogen-doped carbon nanotubes/periodate system attained 100% sulfisoxazole elimination efficiency within 20 min, with the apparent degradation rate increasing by up to 3.5 times as the nitrogen doping level increased. Comprehensive mechanistic studies involving quenching experiments, chemical probe analysis and electron paramagnetic resonance revealed two fundamental degradation pathways: 1) a radical pathway in which the graphitic nitrogen sites on nitrogen-doped carbon nanotubes significantly activated periodate to produce hydroxyl radicals and 2) a non-radical pathway, facilitated by structural defects of nitrogen-doped carbon nanotubes that mediate direct electron transfer between sulfisoxazole and periodate and continue to oxidize sulfisoxazole. This study highlights the potential of N-doped carbon nanotubes to enhance periodate-based oxidation and furnishes critical insights for the rational design of carbon-based catalysts in environmental remediation applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 5","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13762-026-07154-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The volatile organic compounds (VOCs) degradation was performed using titanium dioxide (TiO₂) nanoparticles immobilized on glass fiber tissue (GFT) in a pilot-scale continuous reactor. The performance of elaborated catalyst TiO₂/GFT was studied through the control of different parameters, such as EA inlet concentration (5, 10, 15, 20 mg/m³), flow rate (1, 2, 4 m³/h), relative humidity (5, 50, 90%), air gap (30, 50 mm), and LED intensities (15, 48, 95 W/m²). The exploitation of these parameters allows an understanding of the performance of the novel planar LED reactor, thus the different phenomena involved and the kinetics of the photocatalytic reaction. Monitoring the selectivity of CO₂ enables determination of the reactive oxygen species responsible and the reaction pathways of the photocatalytic degradation of EA. We evaluated the Langmuir–Hinshelwood with the mass transfer approach to obtain the kinetic constants.

The effects of gas flow rate, initial concentration, soil particle size and persulfate (PS) dosage on the degradation efficiency of ATZ in soil were discussed. The experimental results showed that the degradation efficiency of ATZ in soil was the best after 1 mmol/L PS was 77.57%, which was 20.31% higher than that of DBD alone. The more PS dosage was added, the better the experimental removal efficiency was. After 25 min of treatment, the degradation efficiency of DBD plasma was 41.53% higher than that achieved by ozone alone. Through Fukui function analysis, condensed dual descriptor (CDD), Fourier Transform Infrared Spectroscopy (FTIR), and mass spectrometry, the primary degradation pathways were inferred to be dichlorination hydroxylation, alkyl oxidation, dealkylation, and dechlorination. Finally, Toxicological analyses indicate that both the acute and chronic toxicity of the by-products are reduced to different degrees compared with ATZ.
