Under the examination, the panel is investigated for numerous diagnostic tests where we confirmed a long-run co-integration among the studied variables. The econometric technique of the Method of Moment Quantile Regression (MMQREG) analysis supports that GDP is inimical, conversely, digitalization (DIG), renewable energy (RE), and effective governance (GOV) illustrate heterogeneous influences on PM2.5 air pollution. Moreover, the robustness test of the Robust Least Square (RLS) Fully-Modified (OLS), and Dynamic (OLS) confirms and validates the prior outcomes of the Method of Moment Quantile Regression (MMQREG) method. The results indicate that, with the exception of GDP, the explanatory factors effectively reduce PM2.5 air pollution in BRICS countries. Based on these findings, it is suggested that the BRICS member state should give top priority to the development of green and sustainable energy and enhance digitalization (DIG) by importing high-tech solutions. This approach would alleviate the burden on environmental quality. Additionally, the presence of effective governance will play a crucial role in coordinating various institutions, thereby maximizing the benefits derived from the deployment of renewable energy sources.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2615 - 2629"},"PeriodicalIF":2.9,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141369259","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}

PM_2.5 samples collected in Seoul (<i>n</i> = 222), Incheon (<i>n</i> = 221), and Gwangju (<i>n</i> = 224) from September 2020 to March 2022, were chemically characterized.

The conditional bivariate probability function helped to identify each site’s local sources. Joint potential source contribution function analysis identified northeast China and Inner Mongolia as potential source areas of long-range transport pollutants affecting all sites. Forced lifestyle changes due to the pandemic such as limited gatherings while increased recreational activities may have caused different patterns on the biomass burning source. The constraints on old vehicles during the policy implementation periods likely reduced the mobile source contributions in cities that adopted the policy. Secondary nitrate accounted for 40% of the PM_2.5 mass at all sites, implying a significant impact from NO_X sources. While the current policy focuses primarily on controlling primary emission sources, it should include secondary sources as well which may include precursor emissions control. Healthier air quality would be achieved if the policy effects are not limited to local, but also to foreign sources in regions upwind of Korea by intergovernmental collaboration.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2579 - 2599"},"PeriodicalIF":2.9,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11869-024-01584-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141252724","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}

Previous studies have shown the impact of structural racism and the built environment on lung cancer outcomes in Black communities. The current study sought to understand the mediation of airborne pollutants between racial segregation and lung cancer incidence in the United States. Lung cancer incidence data for Black/white populations from 2014 to 2018 were obtained from the CDC. We assessed the impact of segregation on lung cancer incidence and the mediating effects of pollutants SO₂, NO₂, PM_2.5, O₃, and CO in the pathway. We estimated the indirect effect of each pollutant on the interaction between segregation and cancer outcomes. We found that segregation was associated with an 11% increase in lung cancer incidence among Black individuals (IRR 1.11, 95%CI 1.08,1.14) and a 7% increase in white lung cancer incidence (IRR 1.07, 95%CI 1.05,1.09). For Black lung cancer rates, this effect was mediated by SO₂/ NO₂ (23%), PM_2.5 (9.2%), and smoking (36%). For white lung cancer rate, the effect was mediated through SO₂/ NO₂ (25%), PM_2.5 (15%), O₃/CO (4%), and smoking (37.4%). Air pollution is an important mediating factor on lung cancer incidence in more segregated areas, suggesting that the increased pollution in more segregated areas likely also affects white residents, leading to higher levels of lung cancer compared to their counterparts in less segregated areas. Policies targeting polluting sources in segregated areas will be important in reducing lung cancer incidence and disparities therein.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2569 - 2577"},"PeriodicalIF":2.9,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141194401","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 complexity requires innovative ways of assessment and management of air quality within the city. The present work provides a roadmap for hybrid monitoring-based air quality assessment and local air quality management plan (LAMP) for urban hotspot. In this study, fixed and mobile economical portable sensors (EPS) are deployed around a continuous ambient air quality monitoring station (CAAQMS) to assess the trends in air quality of the area. The pre-evaluated EPS are used to accurately capture the hyperlocal variations in the pollution level around an expensive regulatory monitoring station in Delhi, India. The micro-meteorology around the CAAQMS is also taken into account by fixing additional weather stations in different directions. The findings indicate high monthly variations in PM_2.5 (160-201 µg/m³) and NO₂ (41–56 µg/m³) concentrations within a small 2 km radial area around a CAAQMS. The polarplot analysis indicates that local sources are responsible for pollution level. Based on correlation analysis, PM_2.5 dispersion around CAAQMS is correlated well with relative humidity (RH) (r² = 0.58). It is also observed that green area enhance RH and reduce ambient temperature which ultimately influences the pollutant dispersion. This robust assessment of air quality variations at micro scale brings the need for designing of effective and efficient mitigation measures at the local level for hotspots.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2539 - 2554"},"PeriodicalIF":2.9,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141170034","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}

Cohesive information based on interventions to control IAQ is essential for making informed decisions on their deployment and greater uptake.

Proper ventilation improved the test scores of students and chalkboards usage resulted in chalk dust, contributing to PM₁₀ concentration. The leading causes of poor IAQ are inappropriate building envelopes, inadequate ventilation and lack of appropriate legislative interventions.
