However, this approach may lead to an underestimation of potential health effects. The objective of this study is to evaluate the association between ambient exposure to NO₂ assessed by various metrics, and lung function in a cohort of healthy male youth. A cross-sectional analysis of 5,462 subjects was conducted using multivariate linear regression. Exposure to NO₂ was assessed by spatial interpolation using Empirical Bayesian Kriging (EBK). Five different exposure metrics were evaluated over two years, including average concentration, the number and intensity of exceedances of the 24-h NO₂ World Health Organization air quality guideline (AQG), and the number and intensity of 1-h NO₂ peaks. Lung function indices, including percent predicted forced expiratory volume in one second (FEV₁), forced vital capacity (FVC), forced expiratory flow between 25% and 75% of vital capacity (FEF_25-75), and FEV₁/FVC ratio, were assessed. The intensity of the 24-h AQG exceedances was associated with the largest reductions in FEV₁ (-0.82%, 95% CI: -1.61%, -0.03%) and FVC (-1.03%, 95% CI: -1.86%, -0.20%), while FEF_25-75 showed a significant decline only with the 1-h peak intensity metric (-2.78%, 95% CI: -5.02%, -0.54%). The study results support integrating diverse exposure metrics as part of NO₂ chronic exposure assessment, as these metrics may capture a wider range of potential health effects that could be underestimated or overlooked when relying only on average concentrations.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10661-025-13871-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655202","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}

Despite the prevalence of this problem, medium-sized cities in tropical regions remain underrepresented in UHI studies compared to large cities in temperate climates. This study aimed to characterize the UHI effect in a rapidly growing medium-sized city in a tropical region, which has experienced unplanned urban sprawl. Temperature data were collected using data loggers in ten distinct areas of the city. The results revealed a pronounced UHI effect, with higher intensities in the city center and lower intensities in areas with native vegetation. During the dry season, extreme UHI effects (&gt; 6 °C) were observed 10% of the time, with strong UHI effects (4 °C-6°C) present 50% of the month. In contrast, during the wet season, moderate UHI effects (2 °C-4°C) were recorded only 15% of the time. A strong correlation was identified between land use, particularly vegetation cover, and UHI intensity. This study not only sheds light on the dynamics of UHI in this specific tropical city, but also offers relevant insights for other mid-sized cities in similar tropical contexts around the world. The findings provide valuable knowledge for the development of adaptation and mitigation strategies in urban planning, which can be applied globally to cities facing rapid urbanization in hot climates. Furthermore, this research contributes to the advancement of UHI analysis methodologies that can be replicated in tropical and temperate cities, building on previous studies conducted in Brazil and other regions of the world.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668271","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}

Several attempts have been made to control this species in the United Arab Emirates (UAE) deserts but with little success. This study identifies and maps environmental variables influencing <i>P. juliflora</i> habitats using machine learning (ML); employs maximum entropy (MaxEnt) and statistical techniques to estimate its presence in Sharjah, UAE, home to one of its most intense populations; and conducts validation and sensitivity analysis. Eleven environmental variables representing geological, geomorphological, hydrological, eco-indicators, and climatological factors were selected to map the spread of the associated <i>P. juliflora</i> hazard. Variables were selected using collinearity and variance inflation factor (VIF) to eliminate bias, and ML techniques assigned weights based on overall accuracy (OA) and the Kappa coefficient before model implementation. Finally, a statistical comparison with MaxEnt was conducted to map <i>P. juliflora</i> habitats, classifying suitability as very high, high, low, and very low while estimating model accuracy. The results indicated that MaxEnt achieved a higher area under the curve (AUC 0.98) and more logical outcomes than statistical models (AUC 0.85) due to its superior handling of collinearity, complex environmental interactions, and capability of minimizing overfitting. The main findings show that the variable weights for MaxEnt and statistical models are primarily influenced by precipitation (27.0% and 18.18%), groundwater depth (14.9% and 26.8%), and total dissolved solids (TDS) (20.9% and 26.22%), respectively, indicating a shift in habitat distribution towards the eastern regions of the study area. Habitat mapping of <i>P. juliflora</i> is essential for local stakeholders and policymakers in decision-making regarding species conservation, sustainable land use, and climate adaptation. The findings conclude that ML offers a viable approach for habitat modeling of invasive species in similar arid regions worldwide.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655201","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}

Little is known about the occurrence of MPs in DWTPs in Africa, particularly in developing countries like Nigeria. To address this knowledge gap, this study investigated the prevalence and estimated daily intake of MPs in raw water, DWTPs, and tap water in a semi-urban area in Ogun State, Nigeria. Using Rose Bengal staining and optical microscopy, MPs in water samples were identified and characterised using standard methods. The abundances of MPs were 16.13 ± 3.83 particles/L in raw water, 10.74 ± 3.76 particles/L in treated water, and 12.43 ± 3.92 particles/L in tap water. Most of the MPs found in the water samples were classified as fibres, followed by fragments, with a size of &lt; 1 mm. This study showed that the drinking water treatment plant reduced microplastics from raw water by 40%, however, there was an increase in the abundance of MPs in tap water. Residents estimated daily consumption of MPs from tap water varied between 0.31 and 0.44 particles for adults and between 1.2 and 1.69 particles for children. This study addresses a critical gap in understanding microplastic pollution in the water distribution systems and DWTPs. The results also indicated that MPs were not effectively removed, requiring a more sophisticated treatment method to lower human exposure to MPs through drinking water from DWTPs.</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 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655307","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}

An understanding of the types, quantities, and characteristics of menstrual wastes is crucial to formulate and implement safer collection and environmentally acceptable disposal strategies. Therefore, this paper provides a preliminary viewpoint regarding menstrual wastes generated in Sri Lanka with an overview on source separation (SS), disposal methods, and the legal requirements regarding disposal. Commercially available single-use sanitary pads (100% in Colombo capital city; 17–91% in other regions) and reusable cotton cloths (3–83% in other regions, except in Colombo—0%) are the widely used menstrual hygiene products (MHPs). SS is very low, and overall disposal practices are environmentally unfriendly (e.g., 8–84% flushing into toilets).

To fill this knowledge gap, the present study investigated the patterns of species richness, biomass accumulation, and water storage capacity in bryophytes in alpine ecosystems of the Kashmir Himalaya. We conducted stratified systematic field sampling of bryophytes in two major alpine vegetation zones: open meadow above the timberline (AT) and under forest canopy cover below the timberline (BT) in Kashmir Himalaya, along with measurement of five microclimate variables: photosynthetically active radiation (PAR, µmol m⁻² s⁻¹), air temperature (AT, °C), soil temperature (ST, °C), ambient CO₂ concentration (μmol mol⁻¹), and absolute humidity (AH, mmol mol⁻¹). We found a total of 30 bryophyte species, including 3 liverworts and 27 mosses in the two zones with 10 species common. AT zone with greater species richness and more homogenous distribution of bryophytes exhibited higher biomass. Canonical correspondence analysis (CCA) identified PAR and air temperature (AT) as key microclimatic drivers influencing community structure, biomass accumulation, and water storage capacity in above the timberline, while humidity (AH) emerged as the primary factor shaping bryophyte dynamics in below the timberline.

However, climate projections are equally important as they provide future adaptation scenarios for agriculture. This study aims to project climatic scenarios for northern Bangladesh, assess agricultural and meteorological drought, and estimate crop yield using remote sensing and field data. Our simulated data from 21 CMIP6 models (ensemble mean) under SSP2-4.5 scenarios reveal that maximum temperatures will rise in northwestern regions such as Nawabganj, Rajshahi, Naogaon, Dinajpur, and Joypurhat. By 2050 and 2060, the areas affected by rising mean temperatures are expected to expand into other districts. Additionally, projected rainfall is expected to increase in northern districts, particularly after 2040. Drought assessments using the TOTRAM model reveal a water deficit in many areas in 2022, with milder conditions in 2023. Applying SPEI (Hargreaves-Zamani method) from 1984 to 2024, Sirajganj faced moderately dry conditions (14.38%), while Dinajpur had near-normal conditions (63.33%). Our crop yield model, incorporating Leaf Area Index (LAI), NDVI, SAVI, and field data, demonstrates successful yield estimation, with a significant correlation between predicted and observed yields. The multiple linear regression model achieved a 0.82 goodness-of-fit value, indicating effective yield estimation. We emphasize that timely, accurate information dissemination and monitoring are often more effective in preventing agricultural losses than structural developments.
