Summary: Vertical greenery systems (VGSs) have been found to effectively retain airborne particulate matter (PM), especially fine particles, improving the urban air quality. The quantity and composition of PM retained vary among different plant species. The retained PM consists of common elements from natural sources, with heavy metals possibly originating from brakes and tire wear.

Summary: The concentrations of particulate organic carbon (POC) and particulate organic nitrogen (PON) were evaluated in 13 British estuaries, and their sources were assessed using stable carbon and nitrogen isotopes. The results showed a high variability in POC and PON concentrations within the estuaries, indicating inputs and losses of organic material. The land cover of the catchment area appeared to influence the contribution of POC to the total organic carbon flux from the estuary to coastal waters.

Summary: The Government of India implemented a nationwide lockdown to combat COVID-19, resulting in reduced anthropogenic activities and improved air quality in Delhi. The study found that vehicular emissions, domestic coal combustion, and semivolatile oxygenated organic aerosol were severely impacted by the lockdown, while ozone levels and low-volatility oxygenated organic aerosols increased significantly. Other sources were influenced by meteorological conditions rather than the lockdown.

Summary: As human influence on landscapes increases, the sources of organic matter in rivers become more diverse. However, there is a lack of knowledge on the composition and quality of these sources. In this study, we collected samples from four watersheds in Northeast Utah and used isotopes and spectroscopic analysis to characterize the sources of organic matter. We found that the majority of organic matter came from terrestrial sources, except at sites influenced by wastewater or grazing and recreation activities. Further research is needed to understand the drivers of organic matter composition in watersheds with wastewater treatment plants.

Summary: A mobile measurement system was developed to characterize and observe the spatio-temporal variability of particulate matter (PM) in the subway system of Munich, Germany. The results showed that PM concentrations at subway platforms ranged from 59 to 220 μg/m³ for PM10, 27-80 μg/m³ for PM2.5, and 9-21 μg/m³ for PM1. The spatial variability of PM was generally more important than the temporal variability, and significant differences were observed between platforms.

Summary: This study found that short-term exposure to PM2.5 significantly increased blood pressure, with effects appearing in the same hour of measurement and diminishing to insignificance approximately 12 hours later. The exposure-response relationship curves were almost linear without thresholds, but tended to flatten at very high concentrations. No significant associations were observed for PM2.5-10.

Summary: This paper aims to analyze the composition and pollution sources of particulate matter (PM) in the Beijing-Tianjin-Hebei region and its surrounding areas during the heating season. The study finds that direct emission sources have decreased, but secondary pollution is increasing. It also shows that the concentrations of the main PM components increase when air quality worsens. The research further highlights the differences in pollution levels among different regions. These findings are important for the continued management of atmospheric PM pollution.

Summary: This study aims to assess the mass, composition, and sources of PM10 and PM2.5 in Vellore city. Results showed that the traffic site had higher concentrations compared to the residential site. Elements with crustal origin dominated the composition, and SO42- accounted for the highest proportion of ions. Elemental carbon contributed more to PM mass in traffic sites than residential sites. Different sources identified include road dust, crustal material, secondary aerosol, traffic, and cooking.

Summary: This study investigated the spatiotemporal characteristics of sulfur deposition and its regional sources in the Beijing-Tianjin-Hebei region. The results showed higher sulfur deposition in summer than in winter, with the majority attributed to wet deposition. Local emissions had a larger contribution to dry deposition, while non-local emissions had a larger contribution to wet deposition. A comprehensive strategy on both local and non-local emissions is needed to control the ecological risk caused by deposition.

The results show a correlation coefficient greater than 0.6 compared to ground-based data, with a difference generally within +/- 0.04. The underestimation issue compared to OMI data has been greatly improved, and the study provides important insights for research on regional and urban anthropogenic pollution.

Summary: In this study, the formation and evolution processes of secondary organic aerosols (SOAs) during cloud events were investigated. Results showed that clouds promoted the formation of low-oxidized oxygenated organic aerosol (LO-OOA) and more-oxidized oxygenated organic aerosol (MO-OOA). Ozone and nitrate radicals oxidized volatile organic compounds (VOCs) to the precursors of LO-OOA at night, while the hydroxyl radical was the main oxidant for LO-OOA during daytime. In the cloud droplets, LO-OOA was further oxidized by the hydroxyl radical to form MO-OOA. Isoprene was proposed to be oxidized in the gas phase and then absorbed by acidic cloud droplets to form specific organic compounds.

Summary: Given the leveling off in oxidized nitrogen emissions, the atmospheric deposition of reduced nitrogen has become increasingly critical, especially dry deposition. Historical data and modeling show that dry nitrogen deposition has been increasing in China, and this is mainly influenced by changes in precipitation patterns rather than NH3 emissions. This shift towards dry deposition is also observed in North America and Europe. Therefore, stricter NH3 emission controls targeting dry deposition are needed to mitigate potential ecological impacts.

Summary: Current approaches to estimate NOx emissions have limitations in accounting for new and small sources, biomass burning, rapid changes in sources, measurement error, and factors like wind, chemistry, and dynamical effects. This study introduces a new analytical approach that assimilates daily TROPOMI NO2 measurements to estimate daily NOx emissions, with application in a rapidly developing region in Northwest China. The results show a significant increase in emissions in cleaner regions and chemical plants, while emissions decrease in city centers and regulated steel and powerplants. The study provides insights into source attribution and highlights the importance of understanding emissions estimation in relation to remotely sensed measurements and associated uncertainties, especially in rapidly developing regions, for better identification of new, small, and rapidly changing sources.

Summary: This research presents a new model-free inversion estimation framework (MFIEF) to quantify 3 years of daily scale emissions of NOx using TROPOMI NO2 columns and observed fluxes from CEMS in Shanxi Province. The results show that the NOx emissions are 1.86Tg yr(-1), with a daily variability of 1.03 and an uncertainty of 1.05. The highest emissions are concentrated in the Fen River valley, and the NOx/NO2 ratio correlates with the combustion temperature and energy efficiency of energy-consuming sources.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
