Conventional single-variable indices fail to capture the nonlinear, asymmetric dependence between precipitation and temperature—a limitation that is particularly critical in data-scarce, high-mountain catchments, where incomplete drought characterization undermines the reliability of early-warning systems. To address this, we propose a novel vine-copula-based Multivariate Drought Index (VMDI) that integrates the Standardized Precipitation Index (SPI), the Standardized Precipitation Evapotranspiration Index (SPEI), and the Standardized Precipitation Temperature Index (SPTI) within a flexible, station-adaptive dependence-modeling framework. VMDI’s key novelty lies in its station-adaptive canonical vine (C-vine) copula structure in which each index is first transformed into uniform pseudo-observations via rank-based empirical CDFs. Dependence is then decomposed into unconditional (Tree 1) and conditional (Tree 2) pair-copulas with SPTI as the root variable, capturing both direct interactions and joint behavior conditioned on SPTI. Copula families are selected locally via information criteria, and Kendall’s <span>(varvec{tau })</span> values derived from the fitted vine structure yield physically consistent, station-specific index weights. Validated across six stations in the Upper Indus Basin (UIB), VMDI substantially outperforms benchmark indices for precipitation-driven drought signals, achieving agreement improvements of 15<i>–</i>30%, MAE reductions exceeding 50%, skill-score gains of 30<i>–</i>40%, F1-score improvements of 33<i>–</i>37%, and lower-tail dependence coefficients above 0.70, while maintaining low conditional entropy (CE <span>(varvec{&lt;} varvec{0.99})</span>). For evapotranspiration-related drought conditions, JSDI outperforms VMDI relative to SPEI by about 27<i>–</i>38%, with the greatest improvements observed at the glacier-influenced stations of Bunji and Gilgit. Overall, VMDI and JSDI offer a complementary and operationally robust framework for comprehensive drought monitoring across complex mountain catchments.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 32","pages":"16359 - 16379"},"PeriodicalIF":5.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11356-026-38256-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149098321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In order to improve concrete’s mechanical qualities and sustainability, this study looks into recycling waste fibers. This study suggests conducting an experiment to examine the durability and mechanical characteristics of concrete reinforced with recycled nylon fibers. This work’s main goal is to evaluate the efficacy of recycled nylon fibers derived from waste fishing nets in improving the mechanical characteristics and longevity of masonry. Initially, the input data is collected from Concrete Compressive Strength dataset. A Progressive Graph Convolutional Network is used to forecast Concrete reinforced with recycled nylon fiber: its mechanical characteristics (RNRC) (PGCN). Concrete mixtures with zero, one, two, and three percent recycled nylon fibers were tested mechanically using standard testing methods. Compressive, tensile, and flexural strength measures were part of these testing. Compared with conventional concrete, the RNRC containing 3% recycled nylon fibers achieved significant improvements in mechanical performance, Tensile strength increased from 2.67 MPa to 3.45 MPa (29.21%), and compressive strength increased from 23.37 MPa to 28.07 MPa (20.11%) and flexural strength increasing from 3.27 MPa to 8.10 MPa (147.71%) after 28 days of curing. By contrasting RNRC with regular concrete, the study demonstrates how recycled fibers can enhance concrete performance while fostering environmental sustainability. The proposed method is implemented in MATLAB. The study provides a comparison between RNRC with standard concrete, demonstrating that recycled nylon fibers can enhance concrete performance while promoting environmental sustainability.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 32","pages":"16438 - 16454"},"PeriodicalIF":5.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149098192","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}

In this work, polyaniline (PANI), activated carbon derived from <i>Posidonia oceanica</i> (ACPO), and a PANI/ACPO hybrid composite were synthesized and evaluated for Murexide adsorption from aqueous solutions. The approach combines abundant marine biomass valorization with a nitrogen-rich conducting polymer to develop efficient adsorbents for water treatment. Physicochemical characterization confirmed the successful conversion of <i>Posidonia oceanica</i> biomass into hierarchically porous activated carbon (ACPO) and the homogeneous incorporation of PANI in its doped emeraldine state within the hybrid composite framework. Strong interfacial interactions, mainly π–π stacking and hydrogen bonding, ensured good dispersion of the polymer phase and preservation of accessible adsorption sites. PANI and PANI/ACPO exhibited comparable adsorption capacities (333.33 and 322.58 mg·g⁻<sup>1</sup>, respectively), both significantly higher than ACPO (149.25 mg·g⁻<sup>1</sup>), highlighting the dominant contribution of the polymer phase within the composite system. Equilibrium data fitted the Langmuir model for PANI-based materials, while ACPO followed the Freundlich isotherm (<i>R</i><sup>2</sup> ≈ 0.966), indicating surface heterogeneity and multilayer adsorption. Experimental kinetic data were consistent with the pseudo-second-order model. Evaluation of the thermodynamic parameters (ΔG° &lt; 0, ΔH° &gt; 0, and ΔS° &gt; 0) indicated favorable adsorption behavior promoted at elevated temperatures and dominated by physical interactions. Intraparticle diffusion and boundary layer effects contributed to the overall adsorption rate, particularly for ACPO, highlighting the role of pore diffusion in mass transfer. Mechanistically, adsorption is governed by electrostatic forces, π–π donor–acceptor associations between aromatic moieties, hydrogen bonding, and diffusion within the porous network, indicating the coexistence of multiple uptake pathways. Overall, the PANI/ACPO composite combines structural porosity and surface functionality, making it a sustainable adsorbent for efficient Murexide removal from aqueous systems.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 32","pages":"16404 - 16437"},"PeriodicalIF":5.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149098189","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}

A bibliometric analysis is presented to identify publication trends, major research themes, and emerging directions in oil spill research. Subsequently, the review examines major historical and recent oil spill incidents and discusses influence of physicochemical properties and weathering of spilled oil on its transport, fate, and environmental impacts. Effectiveness of physical, chemical, in situ burning and biological remediation approaches are also compared, highlighting their respective advantages and limitations. The review also evaluates recent advances in active and passive remote sensing technologies for oil spill detection and monitoring, including their applicability to surface and submerged oil. Based on the literature, bioremediation emerges as the most environmentally sustainable and cost-effective remediation approach, while remote sensing combined with machine learning offers significant potential for improving the accuracy and efficiency of oil spill detection and response. The review concludes that future research should prioritize integrated monitoring systems, environmentally sustainable remediation technologies, and predictive modeling tools to strengthen oil spill preparedness.

This poses a major obstacle to conservation and to human safety. Following PRISMA 2020 guidelines, this systematic review aimed to explore HWC incidents, contributing factors, mitigation, and technological interventions. The collected information is analyzed for the main categories of conflict, involvement of species, mitigation results, and effectiveness of technological solutions. The results indicated that crop raiding, depredation on livestock, and human attack were the most reported HWC incidents and the most involved species are elephants, tigers, monkeys, and crocodiles. Strong governance, agriculture expansion, habitat fragmentation, and settlement by humans are identified as the major contributors to HWC. The review also confirmed that technological solutions, such as artificial intelligence (AI), deep learning, and machine learning, had positive impacts on the detection, tracking, generation of early warnings, and prediction of conflicts with wildlife. The results of the meta-analysis showed that deep learning techniques had the highest technological effectiveness, 0.83, followed by machine learning (0.76), AI-based systems (0.72), and sensor-based technologies (0.58). The review finds integrated approaches to HWC mitigation using advanced technologies, ecological conservation, and community engagement are the most sustainable ways to minimize HWC and ensure long-term human–wildlife coexistence.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 31","pages":"15918 - 15934"},"PeriodicalIF":5.8,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149079429","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}
