This study presents a multi-year, satellite-based framework for detecting and monitoring water hyacinth in urban lakes using Sentinel-2 multispectral imagery and supervised machine learning. Four classifiers (Support Vector Machine, XGBoost, Random Forest, and K-Nearest Neighbours) were evaluated using classification-based accuracy metrics, including accuracy, precision, recall, F1-score, Cohen’s kappa, and cross-validation F1-score. Although all models achieved high quantitative accuracy, the Support Vector Machine (SVM) classifier demonstrated the most consistent performance, combining high classification accuracy with spatially coherent and cartographically consistent mapping outputs. Independent validation using two lakes excluded from model training and hyperparameter optimisation demonstrated promising transferability of the SVM classifier, with differences between model-derived and manually digitised water hyacinth extents remaining below 2%, primarily due to pixel-level boundary effects. The validated SVM model was subsequently applied to all eligible urban lakes across five major Indian agglomerates (Mumbai, Kolkata, Bengaluru, Chennai, and Hyderabad) for the post-monsoon period from 2021 to 2025. The results reveal pronounced spatial heterogeneity in infestation persistence, with Kolkata and Bengaluru exhibiting the highest number of persistently infested lakes, Mumbai characterised by a single consistently infested lake, and Chennai and Hyderabad showing intermediate levels of persistence. Importantly, infestation was not confined to urban cores but frequently extended into peri-urban and suburban zones. This spatial pattern is consistent with mechanisms reported in previous studies, including nutrient enrichment, wastewater inflows, altered catchment characteristics, and fragmented governance; however, these potential drivers were not evaluated directly in the present study. Overall, this study demonstrates the value of combining classification-based accuracy assessment with spatially explicit, multi-year satellite mapping to support evidence-based prioritisation of urban lake restoration and invasive macrophyte management in rapidly developing cities.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 30","pages":"15810 - 15828"},"PeriodicalIF":5.8,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023621","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 addition, bisphenols and others are associated with thyroid, oestrogenic, and metabolic disorders and have been identified in these products. A scoping review was conducted following the JBI and PRISMA-ScR guidelines. Articles published between 2015 and 2025 were searched in multiple databases. Predefined inclusion and exclusion criteria were applied, and the extracted information was synthesized in a standardized matrix. A total of 223 articles were identified, 27 of which were included after the selection process. Studies have documented the presence of various chemical agents and microplastics (MPs) in infant formula and packaging. The release of millions of particles per liter during the preparation of plastic bottles was reported, along with evidence of prenatal and breast milk exposure. The reported findings include alterations in the intestinal microbiota, changes in immune-related biomarkers and responses, and potential alterations in endocrine function. The available evidence, although limited, suggests that infants are frequently exposed to MPs and EDCs through infant formula and packaging. The reported findings include associations with alterations in the intestinal microbiota, immune-related biomarkers, and endocrine function, although most evidence derives from experimental, animal, or observational studies. The absence of strict regulations and the scarcity of longitudinal studies reinforce the urgency of advancing public policies to control these agents and promoting health education to reduce exposure.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 30","pages":"15285 - 15297"},"PeriodicalIF":5.8,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149015202","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 study, the degradation of two representative azo dyes, Solophenyl Blue (SB) and Cibacron Blue (CB), was investigated using a UV/H₂O₂ advanced oxidation process at 254 nm, generating hydroxyl radicals in situ. The influence of initial dye concentration (1–5 ppm), H₂O₂ dosage (17.6–35.2 mM), and solution pH (3–10) was systematically evaluated. Degradation efficiency strongly depended on these parameters, with acidic conditions (pH 3) and an optimized H₂O₂ concentration of 35.2 mM providing the highest removal rates, reaching up to 99.8% after 180 min of irradiation. Degradation kinetics followed a pseudo-first-order model with high correlation coefficients (R² &gt; 0.95 for all conditions, and &gt;0.99 for most experiments), with apparent rate constants ranging from 0.293 to 0.686 h⁻¹ for SB and 0.018 to 0.044 h⁻¹ for CB, depending on initial dye concentration. UV–visible spectral analysis confirmed progressive azo chromophore cleavage, while density functional theory calculations revealed that SB exhibits a slightly higher electronic chemical potential (<i>μ</i> = −0.162 a.u.) and nucleophilicity index (<i>N</i> = 3.66 eV) compared to CB (<i>μ</i> = −0.164 a.u.; <i>N</i> = 3.48 eV), indicating greater electron-donating capacity and susceptibility to electrophilic HO• attack. From an environmental engineering perspective, the UV/H₂O₂ process offers advantages including ambient temperature operation, the absence of solid catalysts, and water as the reaction medium. Although further investigations using real wastewater matrices and mineralization analyses (COD/TOC) are required, the results demonstrate that UV/H₂O₂ is a promising technology for dye-contaminated wastewater treatment.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"33 30","pages":"15758 - 15783"},"PeriodicalIF":5.8,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149015205","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}

To overcome the drawbacks of traditional treatment techniques, researchers are increasingly exploring two-dimensional (2D) materials as innovative solutions for PFAS remediation.

This review examines a range of 2D materials, including graphene, MXenes, 2D metal-organic frameworks (MOFs), covalent organic frameworks (COFs), layered double hydroxides (LDHs), phosphorene, and hexagonal boron nitride (h-BN). It highlights their efficacy in adsorbing PFAS from water. By exploring the results of performance from available literature, it can be stated that graphene has been among the best-performing materials for a number of reasons. These reasons include its extensive surface area and the ability to alter its surface chemistry to capture PFAS via adsorption. Due to their structural and electrochemical stability, as well as the capacity to remove PFAS from waters of different matrices/conditions, MXenes (although with a limited number of reports) were the second-best-performing material. In addition, among the 2D MOFs and COFs, the ability to adsorb PFAS efficiently was attributed to their engineered porous frameworks. LDHs also have an effective surface for capturing PFAS in the waters because their positively charged metal hydroxide layers and PFAS are negatively charged. h-BN, which possesses a graphene-like layered architecture and provides remarkable chemical and thermal stability.

The viscosity analysis across shear rates illustrates shear-thinning behavior in all mixes, with RS-BM exhibiting higher initial viscosity compared to CS-VR and CS-WR.
