Therefore, this study analyzed the personal PM2.5 exposure characteristics of 86 individuals with allergies living in Seoul using portable monitors and GPS units from February to April 2024. The Kolmogorov–Smirnov test confirmed that the measured PM2.5 concentrations did not follow a normal distribution. Therefore, non-parametric statistical methods such as the Kruskal–Wallis and Wilcoxon rank-sum tests were used to assess statistically significant differences in PM2.5 concentrations. Over 90% of their time was spent indoors, with outdoor environments and schools (weekdays) and transportation (weekends) having the highest average PM2.5 concentrations. The lowest PM2.5 concentrations were consistently observed at home on both weekdays (12.76 μg/m³) and weekends (13.46 μg/m³). Despite this, the time spent at home resulted in the highest integrated exposure levels (weekdays: 58.25%; weekends: 71.14%). The highest levels of time spent and integrated exposure at home were similarly observed across all five subpopulations (child, student, employed, unemployed, and housewife). The average PM2.5 exposure concentrations did not exceed the WHO 24-h PM2.5 exposure guideline of 15 μg/m³. However, analysis of the 5-min interval personal PM2.5 exposure concentrations revealed that participants exceeded this threshold 5.9% and 31.25% of the time on weekdays and weekends, respectively, indicating a higher frequency of high-concentration exposure on weekends. These findings quantitatively identify the primary microenvironments where patients with allergies are exposed to PM2.5 during the day and demonstrate that personalized air quality information provides better insights into personal PM2.5 exposure sources. These results should serve as foundational data for technology development aimed at elucidating the correlation between PM2.5 exposure and allergic diseases and for providing personalized air quality management guidelines.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10661-025-14109-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108443","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}

Accurately estimating and understanding the spatio-temporal patterns of urban road traffic CO₂ emissions plays a fundamental role in developing targeted reduction strategies. However, few studies have estimated CO₂ emissions at the urban road scale with fine spatio-temporal resolution. Therefore, this study adopted a bottom-up method to estimate urban road traffic CO₂ emissions using Global Positioning System (GPS) trajectory data. Urban road traffic CO₂ emissions from individual vehicles are estimated using a vehicle trajectory-driven CO₂ emission model The aggregated results are mapped within Traffic Analysis Zones (TAZ) to create CO₂ emission distribution maps with minute-level temporal and road-level spatial resolution. The Multiscale Geographically Weighted Regression (MGWR) model is employed to analyze the impact of various elements of the built environment on urban road transport CO₂ emissions. Experimental results indicate that road traffic CO₂ emissions in Hangzhou have spatio-temporal heterogeneity. Road traffic CO₂ emission hotspots are concentrated along main roads such as Shixiang Road, the City Ring Expressway, and Shiqiao Road. Further analysis indicates that population density, main road density, availability of bus stops, and length of bike lanes exert a significant influence on urban road transport CO₂ emissions in Hangzhou. These findings enhance our recognition of the combined effects of the various elements of the built environment on urban road transport CO₂ emissions. This study introduces a method for estimating CO₂ emissions at the street level using vehicle trajectory information. It provides high spatio-temporal resolution CO₂ emission distribution maps to support carbon emissions reduction strategies in urban transportation.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108565","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 characterization of composite microbeads was performed using FTIR-ATR, SEM, EDX, and pH_pzc analyses. The surface charge of the adsorbent surface was determined as 6.43 from pH_pzc. From the optimum condition studies, the contact time (60 min), adsorbent dosage (0.1 g/50 mL), and the initial pH (≅ 7) were determined. The raw data were utilized in various non-linear isotherm and kinetic models. The correlation coefficients and error functions indicated that the Langmuir model is the most suitable isotherm model for the adsorption process, with a maximum adsorption capacity of 41.28 mg g⁻¹ for the SA/TW/Fe₃O₄/30 composite microspheres at 298 K. The kinetic and error results indicated that the process adhered to a <i>pseudo-second-order</i> kinetic model. The thermodynamic characteristics indicated that the adsorption process was spontaneous (<span>({Delta G}^{o}=-25.09)</span> kJ mol⁻¹) and endothermic (<span>({Delta H}^{o}=+9.03)</span> kJ mol⁻¹). Moreover, reusability investigations indicated that the composite microbeads can be utilized multiple times. Following the tenth cycle, the adsorption efficiency fell by 32.33%, resulting in a value of 51.23%.

Twenty-five sampling sites were monitored from July 2021 to April 2022.

These FIB values position the Santiago-Guadalajara River as one of the most polluted rivers globally since it significantly exceeds the regulatory limits at the monitored sites, indicating insufficient sanitation infrastructure throughout the basin. A high level of correlation was found between FIB concentrations and monitored stream tributary flows, which allowed modeling the behavior of the FIB with respect to the flow regime throughout the basin. Quantitative microbial risk assessment revealed specific stations with elevated infection risks from <i>Escherichia coli</i> exposure.

This study focuses on sustaining glacial landforms and paraglacial processes in the Byans Valley of upper Kali Ganga catchments. Limited glacial action-induced terrain change and infrequent paraglacial events occurred in the lower region. On the contrary, paraglacial processes were highly active in the highest regions where a mountain style of glaciation was established, producing a large number of moraine and rock glaciers. The primary aim of this study is to identify the glacial landforms since they have unique characteristics that are especially tied to glacial processes and act as indicators of climate change. The glacial chronology from the Central Himalayan regions indicate that the last major glacial advance probably occurred during the Late Holocene. Following this, the deglaciation is represented by the recessional moraine, outwash plain, and the proglacial lakes proximal to the present glacier, which can be attributed to the warming climate. The presence of moraine mounds in the vicinity of the modern snout probably represents a minor re-advancement during the Little Ice Age (LIA). The geomorphic expression of a steady decline in ice cover is eloquently manifested by the presence of the supra-glacial lakes and the increasing size of the pro-glacial lakes. The spatial data on the glacial landform features in the region is envisioned to help with the reconstruction of a paleo-glaciological setup using dating methodologies, which will finally fill the information gap concerning the glaciation in the region.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084958","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 study aimed to quantify GHG emissions associated with waste management practices in the region. LCA was employed to evaluate the environmental impacts of waste management practices, identifying key areas for improvement and sustainable solutions. Contribution of waste management practices of composting, material recovery facilities, waste-to-energy, RDF facilities, landfills, incineration, and waste transportation were assessed in the state of Himachal Pradesh. The municipal solid waste management infrastructures in the state contributed to 3,98,098 tCO_2eqyr⁻¹ emissions of which waste transportation and landfills were identified as the major sources, highlighting the constraint of infrastructure in rural areas of the region. They made up 82% of all the emissions from waste management infrastructures in the state. The LCA studies confirmed that landfills for MSW were the major source of environmental incompatibility in the state. However, material recovery and fuel production practices in MSW management facilities drastically reduced the impacts on indicators, namely, abiotic depletion, acidification, freshwater aquatic ecotoxicity, human toxicity, and ozone depletion potential. The findings highlight the pressing need for efficient waste management facilities in the state to bolster climate change resilience and environmental compatibility, given the current inadequacies in infrastructure, processes, and skilled manpower.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084877","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}

To mitigate these effects, decades-long afforestation campaigns have been implemented. However, the effectiveness of these efforts remains understudied, which hinders our understanding of their sustainability and replicability. This study explored the efficacy of these afforestation campaigns, usually conducted in woodlots by analyzing seven decades (1950s to 2020s) of changes in land use and land cover (LULC) in Urambo, Uyui, and Kaliua districts, which are the leading tobacco production areas. LULC classification relied on open-source data and software, utilizing Quantum GIS and Landsat imagery for 2000 and 2020, as well as country’s topographical maps of 1956 and 1976. This study adopted cadastral surveying coupled with digitization of satellite images to estimate area cover of woodlots. The study revealed a 62% decline in forest cover from 28,985 in 1956 to 8,811 sq. km in 2020. This decline is largely due to population growth, which has increased demand for land for settlement and shifting cultivation, leading to more bush and grassland. However, afforestation campaigns have deemed ineffective, as the total area reforested (455 out of 32,715 sq. km) is significantly less than the annual rate of forest loss (315 sq. km per year). The inefficiency of afforestation efforts is partly attributed to the widespread planting of eucalyptus trees, an exotic species that offers limited benefits to farmers, making it an unpopular choice for wood production, including tobacco curing. This study highlights the importance of using productive species <i>Gmelina arborea</i> (beechwood tree) in woodlots, implementing clear fallow periods, and efficient harvesting cycles in plantation forests to ensure regeneration and maintain a balanced ecosystem.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084876","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}

Here, it has been tried to examine the mouza-wise HEC risk based on crop-raiding incident in the stated two parts of West Bengal. Two important parameters, the number of crop fields raided and the total number of crop fields present but not raided, were taken into consideration to measure the HEC risk. The result shows that the Jhargram (0.75–0.98), Medinipur (0.68–0.89), and Rupnarayan (0.68–0.89) forest divisions are the highest HEC risk areas in West Bengal. The most dominant factor as determined from the principal component analysis is the lack of fodder and other biological requirements that are one of the basic needs for survival of the elephants within the forest (0.864). The total risk for raiding crop is 3.21 and 2.93 in the two parts of West Bengal. Here, the paddy and vegetables fields are more prone to be raided. Moreover, descriptive statistics were also used to explain the patterns of crop-raiding incidents. The findings may provide a way out for the sustainable management of HEC risk like establishment of micro-habitat, creation of elephant proof trench/electric fences, and rapid plantation of indigenous plant species in the vacant forest areas, thereby helping the policymakers in wildlife conservation.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074103","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}
