The results indicate that increased humidity and temperature might reduce PM₁₀ levels by enhancing particle dispersion and deposition. Positive correlations between PM₁₀, NO, and NO₂ suggest a shared origin, likely from vehicle emissions. To further analyze PM₁₀ behavior, prediction models were developed to categorize PM₁₀ levels as \"good\" (≤ 45 μg/m³) or \"bad\" (>45 μg/m³) based on a air quality guidelines from WHO. The performance of the random forest (RF) and logistic regression (LR) algorithms were evaluated and compared. Additionally, the influence of atmospheric variables and pollutant concentrations was also assessed to determine their impact on PM₁₀ predictions. RF model demonstrated the highest predictive performance for PM₁₀ level. Results indicate that NOx (NO₂ and NO) significantly contribute to PM₁₀ formation, likely due to shared anthropogenic sources. Temperature, humidity, and wind speed also impact PM₁₀ predictions, though to a lesser extent than pollutant concentrations.

The study investigated the effects of g-C₃N₄ content, photocatalyst loading, dye concentration and type, solution pH, scavengers, and oxidants on the photocatalytic degradation process. The g-C₃N₄ photocatalyst, with a high surface area of approximately 100 m²/g, exhibited a combined adsorption and photocatalytic degradation effect for rhodamine B (RhB) removal. Notably, nearly 100% RhB degradation was achieved using 1 g/L of the optimized 50% g-C₃N₄/TSBW heterojunction photocatalyst with an initial RhB concentration of 10 mg/L after only 20 min of visible light exposure. This high performance resulted from the synergistic effect of combining g-C₃N₄ with TSBW, facilitated by the formation of a type II heterojunction between TiO₂ and g-C₃N₄, which effectively suppressed the recombination of photoinduced charge carriers. Trapping experiments provided mechanistic insights into RhB photocatalytic degradation, revealing the significant contribution of superoxide radicals (•O₂^-).

However, zinc sulphate (ZnS) may act as an acute stress signal to alleviate the toxic effects of Cd stress by upregulating the antioxidant defense mechanism and enhancing nutrient absorption. This study aimed to evaluate the impact of ZnS foliar application on mitigating the toxic effects of Cd stress in maize seedlings. The treatments were a) ZnS applications (0 ppm, 20 ppm, and 40 ppm), b) maize varieties, V1 = Malka-16 and V2 = Sahiwal Gold, and Cd stress (0 mg kg^-1, 20 mg kg^-1, and 40 mg kg^-1). Cadmium stress significantly reduced the growth and chlorophyll content in maize varieties as compared to the control. Results have revealed that plant growth and photosynthetic pigments were reduced under Cd stress as plant height and carotenoid contents decreased by 41.5 and 45.0% in Malka-16 and 12.7 and 50% in Sahiwal Gold compared to the control. Nutrient uptake was also significantly affected by Cd stress as calcium, phosphorus, potassium, and sodium were reduced in the roots, stems, and leaves in both maize varieties. However, ZnS treatments successfully reduced the toxicity of Cd stress in maize varieties and improved plant growth and development as compared to the control.

POFA, garnet waste, and sawdust were blended individually with asphalt grade 60/70 with varied amounts of 0% (control), 3%, 6%, and 9%. Moreover, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray fluorescence (XRF), as well as X-ray diffraction (XRD) were utilized to analyze the microstructures of raw waste materials.

This paper quantifies the effects of a small artificial lake-Dridu from Romania (with complex usage) on the environment in the context of CC, estimating the blue water footprint (WF) and carbon footprint (CF) under different use scenarios. Thus, an analysis of the evolution of CF and WF is conducted until 2100, considering forecasts of changes in average temperatures, as well as a partial coverage of the lake's surface with floating photovoltaic systems (FPV). During the study period from 2017 to 2021, the average WF was 0.054 million m³, and the carbon intensity was 120.23 kg CO₂e/MWh. By covering 2 ha of the reservoir's surface with FPV, the production and release of CO₂ and CH₄ into the atmosphere decrease, on average, by 30% for WF and 28.13% for CF. For the CC scenarios, it is observed that WF will increase by an average of 10.4%, while the carbon footprint shows no significant variations. It is worth mentioning that this type of approach, e.g., impact of FPV on WF and CF, as well as the use of FPV as a measure of coping with CC, has not been studied yet in any region of Eastern Europe. This study, given that it deals with relatively new technologies (FPV), has some gaps, since the CF is computed based on estimates, not on measured data. However, the results and the methodology currently presented can be used by various stakeholders to identify the best coping mechanism for preserving the water quantity and for generating clean energy. Also, these types of studies can be a good stimulus for the authorities to develop and permit the placement of FPV on small reservoirs and to investigate the effects of such projects in terms of energy, FPV efficiency, water quantity, and quality, as it will allow the actual quantification of different effects and benefits brought by this technology (water quality indicators, GHG emission, reduction of evaporation, FPV energy output).</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332263","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}

Biodiversity-rich regions like Mizoram, a northeastern Indian state known for its lush forests and a part of Indo-Burma Biodiversity Hotspot, are particularly vulnerable to these fires. Between 2012 and 2021, Mizoram incurred losses amounting to approximately $8,910,000 USD due to wildfires. This study addresses the urgent need for high-resolution forest fire susceptibility mapping for southern Mizoram (Lunglei, Lawngtlai, Serchhip, and Tlabung), highlighting the region's ecological fragility and vulnerability. We employed six machine learning (ML) algorithms-AdaBoost, Decision Tree, Gaussian Process, K-Nearest Neighbor, Random Forest, and Support Vector Machine and analyzed ten wildfire conditioning factors. These factors include topographical elements (DEM, slope, aspect, curvature, TWI), vegetation indices (pre-fire EVI, pre-fire VARI), anthropogenic factors (LULC), and solar radiation. A forest fire inventory was created using high-resolution satellite images from April 2021 through visual manual interpretation. Feature importance analysis using Gini Impurity revealed that pre-fire NDMI, EVI, DEM, aspect, and solar radiation were the most significant contributors. Performance metrics such as average accuracy, precision, recall, F1-score, area under the curve (AUC), and G-mean were used to evaluate the ML algorithms. AUC values ranged from 0.84 to 0.91, with accuracy scores between 0.74 and 0.81. Among the models, the Random Forest algorithm demonstrated the best performance across all metrics. Lawngtlai exhibited the highest susceptibility (64%, 869.66 km²), followed by Tlabung (38%, 956.09 km²), Lunglei (27%, 556.57 km²), and Serchhip (21%, 21.72 km²). Overall, 37.01% (2677.21 km²) of the study area was classified as highly susceptible. Our analysis further indicates that lower elevations and specific aspect orientations-namely East, Southeast, Southwest, and South-substantially influence forest fire susceptibility. Finally, the forest fire susceptibility map was validated using high-resolution Planet images.
