Therefore, a real-time monitoring campaign was carried out in 2023 from February 2nd to April 10th inside a naturally ventilated Italian church where the size distribution of airborne particles and the concentrations of total volatile organic compounds (TVOCs), benzene, toluene and carbon dioxide (CO₂) were continuously monitored. Moreover, tailored experimental sessions burning four different typologies of incense were carried out inside a large-scale test chamber under controlled micro-environmental conditions (temperature, relative humidity and air exchange rate) miming priest actions during the liturgical celebrations. Investigations inside the church highlighted a significant increment of PM₁₀ (max value: 203 μg/m³), PM_2.5 (max value: 171 μg/m³), PM1 (max value: 108 μg/m³),TVOCs (max value: 3.9 ppm) and Benzene (maxvalue: 5.86 μg/m³) concentrations during liturgical celebrations and in correspondence of incense use. These peak concentrations were significantly higher than the limit values established by recent WHO air quality guidelines (AQGs) for outdoor. Moreover, the combustion tests highlighted that the qualitative and quantitative differences in pollutants concentrations emitted by incense combustion were linked to the intrinsic variability of combustions performance rather than to the typologies of incense and charcoal used.</div></div>","PeriodicalId":250,"journal":{"name":"Atmospheric Environment","volume":"350 ","pages":"Article 121143"},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Aerosols, through atmospheric deposition, can directly or indirectly influence the growth and distribution of marine organisms, while changes in cloud cover and aerosol presence can alter solar radiation levels. Gaining insight into aerosol-cloud interactions in the Northwest Pacific and their effects on marine plants can support the sustainable development and utilization of ocean resources. This study utilized aerosol optical depth (AOD) data from MODIS to examine the spatiotemporal distribution and potential sources of aerosols over the Northwest Pacific. Additionally, the study integrated MODIS data on cloud optical thickness of ice and liquid (COTI/COTL), cloud water path of ice and liquid (CWPI/CWPL), effective particle radii of ice and liquid clouds (CERI/CERL) and ocean net primary productivity (NPP) data from Oregon State University to analyze aerosol-cloud interaction patterns and their effects on marine phytoplankton. The results show that in the fishing grounds of the northwest Pacific (38°-46°N, 150°-175°E), the sustained northward migration and intensification of the subtropical high during summer weaken the upper-level atmosphere from Asia. This results in aerosols in the local marine area predominantly originating from the clean marine (CM) aerosols of the Pacific region, which typically peak from June to August each year (0.9). Aerosols in both the fishing and spawning grounds (20°-30°N, 130°-170°E) significantly affect the CWPI and CWPL, with those in the fishing grounds exerting a stronger influence. Furthermore, as the net primary productivity (NPP) in the fishing grounds is primarily influenced by clouds, aerosols indirectly impact local phytoplankton photosynthesis by suppressing cloud formation. In contrast, in the spawning grounds, the proximity to the East Asian continent leads to greater influence from human activities, with aerosol deposition and river inputs playing a dominant role in the local marine environment.</div></div>","PeriodicalId":250,"journal":{"name":"Atmospheric Environment","volume":"350 ","pages":"Article 121151"},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

First, a catalytic stripper was used to heat the sampling line to 350 °C, minimizing the impact of non-BC sampling. This allowed for the correction of the non-linearity of ATN due to the rBC loading effect. After applying the correction formula derived from this process to the measured eBC_AE51, further correction was applied to account for the filter loading effect of non-BC, estimated from atmospheric measurements through an unheated sampling line. This study introduces an innovative system for accurately quantifying high-resolution vertical profiles of BC mass concentration. By combining data from the AE51 and a miniaturized optical particle counter, the system applies precise corrections to enhance measurement accuracy at various altitudes.

However, traditional microbial monitoring methods are constrained by their temporal resolutions. To address this, we employed a real-time light-induced fluorescence-based bioaerosol monitoring instrument to detect the dynamics of particulate matters (PM) and classify them into fluorescent biological aerosol particles (FBAPs) or non-FBAPs based on the intrinsic fluorescent feature of bioaerosols. We deployed this sensor on the platform, in the station hall, and outdoors at a typical subway station for 18 days in Tianjin, China. The results showed that FBAP and non-FBAP concentrations on the platform were roughly 2 and 3 times higher, respectively, than those in the station hall, and approximately 3 and 4 times higher than outdoor levels. Notably, the bacteria-like particle levels on the platform were 20 times higher than those outdoor values during most periods. The concentrations of PM, dominated by non-FBAP, peaked during the morning rush hours both on the platform and in the station hall, while the bacteria-like particles reached their lowest levels in the morning, presumably caused by the elevated metal particle levels when trains started operating that inhibit bacterial survival. Train operations strongly influenced non-FBAP concentrations on the platform, as evidenced by the 7-min periodic cycle in the particle autocorrelations corresponding to train schedules. By contrast, the particle levels in the station hall did not show train-related patterns in autocorrelations but showed stronger correlations with the environmental parameters. The revealed dynamic patterns of non-biological and biological airborne particles in the subway station provide insights for mitigating particle exposure in the future.</div></div>","PeriodicalId":250,"journal":{"name":"Atmospheric Environment","volume":"350 ","pages":"Article 121142"},"PeriodicalIF":4.2,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study is based on well time-resolved continuous measurements of ambient monoterpene concentration at an urban site in western India during January–May 2020, coinciding with the winter-to-summer and COVID-19 pre-lockdown to lockdown transitions. Despite large day-to-day variations of α-pinene (7–76 ppt) and β-pinene (6–55 ppt) their levels in winter were slightly higher than in summer. The trends in monoterpenes concentrations do not directly reflect the impact of enhanced biogenic contributions in summer due to counterbalancing effects of increased rates of oxidation and dilution. However, the increase of ∑α+β-pinene/∑BTEX ratios from 5 to 13 in winter to 61–87 ppt ppb⁻¹ in summer highlights the impact of increased biogenic contributions at higher temperatures. The very high ∑α+β-pinene/∑BTEX ratios during the strict COVID-19 lockdown phases than the pre-lockdown period could be additionally attributed to the reductions of anthropogenic emissions. The estimated relative daytime biogenic contributions to α-pinene increased from 66 ± 10% in January to 88 ± 13% in May, while that of β-pinene from 56 ± 8% to 70 ± 19%. Overall, depending on the season, the complex interplay between the variability in anthropogenic activities, biogenic emissions, and photochemical/meteorological factors controls the ambient air variability of monoterpenes.
