When the temperature was modeled as a confounding factor, the relative risk (RR) of mortality associated with a 10 µg/m³ increase in PM₁₀ and PM_2.5 (lag 0-2), and a 10-ppb increase in NO₂ (lag 0-2) and O₃ (lag 0-7) was respectively 1.0096 (95% Confidence Interval (CI): 1.0073, 1.0118), 1.0134 (95% CI: 1.0099, 1.0170), 1.0172 (95% CI: 1.0122, 1.0222), and 1.0164 (95% CI: 1.0093, 1.0236). Regarding temperature as an effect modifier, the combined effects of air pollution and temperature were observed as a U-shaped pattern, where the effects of PM₁₀, PM_2.5, NO₂, and O₃ on mortality were greater at low (< 1st percentile) and high (> 99th percentile) temperature days compared to those at moderate temperature days (1st - 99th percentile). The pattern of combined effects of air pollution and temperature remained robust even when different temperature percentiles were employed, except for that of NO₂. Furthermore, the estimated effects of PM₁₀, PM_2.5, NO₂, and O₃ on mortality at high-temperature days were mitigated by high green density. Findings of this study revealed that extreme temperature (both hot and cold) could exacerbate the effect of air pollution on mortality, and higher green density mitigate the combined effects of air pollution and high temperature.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the work assesses the effect of material air permeability and the influence on insulation at the various environmental conditions. A systematic approach revealed that material air permeability was primarily related to forced convective heat transfer and requires a minimum air layer thickness of 5 mm and wind speed of 1.3 m/s to be observed. Additionally, it was found that traditional methods of evaluating material thickness, such as ASTM D1777, apply a high force to the material and do not give an accurate measurement of uncompressed thickness- which is more indicative of what would be experienced during normal wear conditions.

Urban regeneration has been presented as a solution to those problems. This study investigates whether urban regeneration provides environmental benefits in terms of mitigating urban heat islands (UHI). Two large-scale urban regeneration areas in Ankara, the New Mamak Urban Regeneration Project (NMURP) and the North Ankara Urban Regeneration Project (NAURP), are anaylzed, both of which have been undergoing transformation more than a decade. Landsat 5 and Landsat 8 satellite images were used to detect the land use-based changes in the surface UHI, based on UHIER index, between 2005 and 2022, CORINE datasets were utilized for land use classification in the study areas for comparison. The results show that UHI values decreased in entire project areas due to removal of squatter settlements and partial completion of the transformation. However, when the local variations are observed, it is concluded that UHI values increased in already transformed sites as a result of high built-up densities, where complex cultivation pattern is replaced by urban fabric in NMURP, agriculture and construction sites replaced by urban fabric, natural grasslands replaced by road network and urban fabric, and urban fabric is replaced by urban green areas and construction sites in NAURP.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim is to identify the best predictor for Exertional Heat Illness (EHI) and Exertional Heat Stroke (EHS) in outdoor races. Based on a 20-year dataset from the Falmouth Road Race, generalized linear regression was used to analyze the relationship between the incident rate and the predictors, and model performance was evaluated by leave-one-out cross-validation. The modified version of PET, mPET, had the highest explanation for EHI rate at 59%, with WBGT at 45.7%. UTCI and PET had the lowest explanatory power, 21% and 17.9% respectively. For EHS, WBGT had the highest explanatory power at 58.1%, and mPET followed with 49.1%. In cross-validation for EHI, the predicted values of mPET strongly correlated with the actual values (cor = 0.767, p < 0.05). In cross-validation for EHS, the predicted values of WBGT significantly correlated with the actual values (cor = 0.604, p < 0.05).

We aimed to describe heat exposure according to air pollution and vegetation co-exposures, individual social position and socio-economic context of residence among French pregnant women. We studied 12,235 pregnant women from four mother-child cohorts. Exposure to heat (intensity, duration, severity), particulate matter, nitrogen dioxide (NO₂), ozone (O₃), and vegetation during summer were estimated at the women's residences. Socio-economic context of residence was assessed using the European Deprivation Index (EDI). Cumulative overexposure to heat, air pollution and vegetation were estimated according to reference values. Three profiles of heat exposure, multi-exposure and individual social position, were created using multivariate analysis and unsupervised clustering. Associations of the profiles of heat exposure and multi-exposure with air pollution, vegetation, individual social position and EDI were described using Wilcoxon tests and polytomous regressions. About one-third of pregnant women had a high heat exposure profile combining intense, severe and durable exposure. Depending on the location and year of pregnancy, 27-88% of women were overexposed to heat, air pollution and lack of vegetation. The relationships between profiles of heat and multi-exposure with air pollution, vegetation and individual social position and socioeconomic context of residence depended on the geographical and temporal context. No clear differential exposure pattern across social strata was found. Co-exposure to heat, air pollution and lack of vegetation is common among French pregnant women. Protective measures against summer heat would apply to all pregnant women, as heat exposure represents a universal risk, regardless of socioeconomic status.
