The visible emission of dust from this area raised concerns for public health and to address this, the municipality has monitored the fine particulate matter (PM<sub>2.5</sub>) concentration and dust deposition since 2015. Here, this monitoring data served to assess spatial and temporal changes and to evaluate the potential contribution of industrial and meteorological processes to these changes. We observed high temporal variability in both PM<sub>2.5</sub> concentration and dust deposition, and high spatial variation in dust depositions. Dust originated from local sources such as industry and traffic, but industrial activities could not explain the observed spatial variability, and concentration and deposition fluxes did not significantly increase over the years despite the extension of industrial activities. Meteorological factors such as rain, wind speed, wind direction, as well as topography exerted an important influence, but could also only partially explain the observed variability in both dust concentration and deposition. Furthermore, the PM<sub>2.5</sub> concentration and dust deposition are not significantly correlated, which highlights the challenges in appropriate dust monitoring. It follows that such monitoring efforts, though meeting national standards, require improvement to assess risks accurately. Our study illustrates that in areas with such high complexity of industrial activities, the high variability of dust load and deposition must be considered to evaluate implications for public and environmental health, adherence to guidelines, and mitigation strategies.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 11","pages":"2445 - 2459"},"PeriodicalIF":2.9,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11869-024-01581-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140980704","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}

In this article, we used the Ultraviolet Aerosol Index (UVAI) and Multi-Angle Implementation of Atmospheric Correction (MAIAC) aerosol optical depth (AOD) from January 2005 to December 2021 obtained by the Ozone Monitoring Instrument (OMI) and MODIS respectively to investigate the Spatio-temporal patterns, annually and seasonal variations of absorbing aerosols, and interaction of aerosols with various meteorological parameters (rainfall, temperature, wind speed, e.g.) over Saudi Arabia (SA). Using the Hybrid Single Particle Langrangian Integrated Trajectory (HYSPLIT) model, we also identified pollution sources in SA's main cities. We also go through the natural and manmade factors that influence absorbing aerosols. Significant UVAI and MAIAC AOD values were observed high in the eastern and central regions of SA and low in the northern and western regions. Over SA, the average UVAI and MAIAC AOD are increasing at 0.93% and 0.83% per year respectively. UVAI has a favorable relationship with temperature in SA's eastern regions. In SA, UVAI has a positive and negative correlation with energy consumption and secondary industries of 0.787 and -0.52, respectively. Therefore, this study will help policymakers to identify the major hotspots and variability of aerosols in SA. Moreover, the contribution of different anthropogenic activities in polluting the atmosphere will also be analyzed in this study.

Providing personalised photo-pollution exposure warnings and dose monitoring to an individual through a smartphone app could help in reducing skin ageing and degradation as well as in managing skin conditions (for example Atopic Dermatitis). However, accurate monitoring is challenging without a potentially expensive or cumbersome sensor device. In this work we present an innovative satellite-based air pollutant monitoring software service, ExpoPol, developed by siHealth Ltd. ExpoPol synthesises several inputs including live satellite imagery in real-time into an artificial intelligence (AI) model to provide assessment of the exposure of a smartphone user to relevant air pollutants, such as nitrogen oxides (NO<sub>x</sub>), poly-aromatic hydrocarbons (PAH) and ozone (O<sub>3</sub>). When combined with siHealth’s patented technology HappySun® for solar radiation monitoring, ExpoPol can effectively provide a sensor-less personal skin photo-pollution dosimetry. By downscaling satellite data using local geographic data, ExpoPol is capable of monitoring pollutants with street-level resolution and global coverage in near real-time. We evaluate the accuracy of ExpoPol against ground-station monitoring data for three pollutants across three continental regions (Europe, Asia, North America) and find R<sup>2</sup> values of 0.62, 0.65, 0.74 for PM<sub>10</sub>, PM<sub>2.5</sub>, NO<sub>2</sub> respectively.

The presented system can support the real-time automatic assessment of the user’s skin exposome, anywhere and anytime.

However, the temporal and spatial resolution of data on MP pollution and knowledge of their atmospheric behaviour and fate is still very limited. Hence, we investigated MP wet and dry deposition in Central Germany and examined the role of weather conditions on MP contamination levels. Monthly samples of dry and wet deposition were taken over an eight-month period (05/2019-12/2019) and analysed by micro-Fourier-Transform Infrared spectroscopy (µFTIR) down to 11 μm particle size and one dry deposition sample was subjected to Raman analysis to determine plastic particles down to a size of 0.5 μm. MP in a size range from 11 μm to 130 μm were detected in all wet deposition samples and in 4 out of 8 dry deposition samples by µFTIR. Polypropylene particles were found most frequently and accounted for 62% and 54% of all particles in wet and dry deposition samples, respectively. Over the eight-month period, wet deposition of MP slightly dominated at the study site and comprised 59% of the total MP deposition. The MP mean total (wet + dry) deposition flux (DF) was 17 ± 14 MP m<sup>− 2</sup> day<sup>− 1</sup>. Extensive Raman analyses of an exemplary dry deposition sample revealed additional plastic particles in the extended size range from 1 to 10 μm resulting in a deposition flux of 207 MP m<sup>− 2</sup> day<sup>− 1</sup>. Our results suggest that MP analysis by µFTIR down to 11 μm may underestimate DF at least by an order of magnitude. More comprehensive studies on submicron plastics and nanoplastics are needed to fully assess air pollution by plastic particles.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 10","pages":"2247 - 2261"},"PeriodicalIF":2.9,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11869-024-01571-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140663539","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}

Along with this development, problems such as the decrease in air quality in and around the airport also arise. In this study, it is tried to calculate pollutant emissions occurring in 2022 during the LTO cycles of Denizli Çardak Airport in Turkey. These calculations are based on the information obtained from ICAO Engine Emission Data Bank and flight information published by the General Directorate of State Airports Authority (GDSAA). As a result of the data obtained, 74.64 ton/year pollutants (NOx-37.148 t/y, CO-35.398 t/y and HC-2.094 t/y) were calculated for 2022 at Denizli Çardak Airport. Of all emissions, NOx accounted for 50%, CO 47% and HC 3%. In the LTO cycle, the most fuel is burned in taxi cycle and pollutant emissions produced in this cycle are greater. With a 2 min reduction in taxi time, there will be an approximate 6.8% reduction in the total emission rate in the LTO cycle. Similarly, with a 4 min reduction in taxi time, there will be a 13.72% reduction in the whole emission rate in the LTO cycle. Unlike other studies, in this study the emission rates of various engines were compared. It has been calculated that the amount of pollutant emissions produced by the new generation Boeing 737 MAX LEAP-1B powered aircraft in LTO cycle is 25% less than the amount of pollutant emissions produced by the Airbus A320 NEO LEAP-1 A powered aircraft. The biggest factor here is that the emission of CO pollutants is less. Considering the emission rates produced by these four different engines (B737-800 CFM56-7B, A320 V2500-A1, B737 MAX LEAP-1B, A320 NEO LEAP-1 A), the Airbus A320 V2500-A1 engine is a more environmentally friendly engine than the other engines.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 10","pages":"2395 - 2403"},"PeriodicalIF":2.9,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11869-024-01579-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140662998","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}
