This comprehensive literature review synthesizes current knowledge on the sources, distribution, and health risks associated with airborne MPs. The significant rise in global plastic production has concerns about its harmful effects on the environment and human health. Microplastics, being pervasive across various ecosystems, can traverse the food chain. They also have the potential to disperse through the air. Various studies have emphasized the role of airborne MPs as carriers for toxic substances, impacting environmental and human health. This review delineates the sources of atmospheric MPs, stemming from primary sources such as commercial products and secondary sources from larger plastic degradation. Moreover, a comprehensive understanding of MPs’ size, shape, and polymeric composition is crucial for a thorough assessment of their potential impact on human health. Notably, while airborne MPs tend to encompass a variety of shapes, including fibers, fragments, and granules, their health implications vary. Fibrous MPs, despite their visibility, raise concerns due to entanglement and prolonged residence within organisms. However, research suggests that most of the airborne MPs consist of smaller particles, highlighting the need for further investigation into their impact on health. Although advancements have been made in understanding airborne MPs, substantial gaps remain. Standardized sampling methods, comprehensive risk assessments, and long-term epidemiological studies are essential to unravel the health implications of prolonged exposure to these omnipresent particles. This literature review underlines the need for continued research to fully comprehend the sources, distribution, and health risks posed by airborne microplastics, offering insights into potential mitigation strategies and future research directions.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2661 - 2674"},"PeriodicalIF":2.9,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141501467","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}

In this study, VOCs were monitored by a real-time online instrument for three years (from April to September 2020–2022) in Jinzhong, Taiyuan Basin, and comprehensively reported the components characteristics, sources, and ozone formation potential (OFP). The interannual variation in VOCs concentration increased from 11.2 ± 8.2 ppbv in 2020 to 12.9 ± 9.2 ppbv in 2021 and 13.3 ± 8.9 ppbv in 2022. Alkanes were the major VOC groups, accounting for 55.8-64.6% of the total. However, alkenes were the primary contributors to OFP, accounting for 64.3-74.2%. After meteorological normalization, the concentrations of alkanes, alkynes, and aromatics were slightly higher than the observed concentrations, indicating that meteorological conditions favored the dispersion of pollutants. Based on positive matrix factorization (PMF) model, coking sources (28.4-30.7%), LPG/NG usage (17.9-30.5%), and vehicle exhaust (17.5-23.2%) were the major sources of VOCs during the three year observation period. The contributions of solvent usage, biogenic sources, and combustion sources increased with each year. Coking sources (47.5-52.7%) and vehicular emissions (23.2-32.3%), particularly ethylene, were major contributors to OFP. The analysis of potential source regions for VOCs concentration pointed to the southwest region (Qingxu, Wenshui, Xiaoyi, and Jiexiu) as a key emitter of VOCs. Therefore, the study recommends effective mitigation of ozone issues in Jinzhong and the downwind areas of the Taiyuan Basin by controlling coking sources and vehicular emissions, particularly targeting ethylene emissions.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2631 - 2646"},"PeriodicalIF":2.9,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141348513","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}

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}

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}

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}

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.
