Mechanistic study on photochemical generation of I•/I2•− radicals in coastal atmospheric aqueous aerosol

Using the Sentinel-3B Satellite in Geospatial Analysis of Suspended Aerosols in the Kiev, Ukraine Region

“…Therefore, this study, which evaluates the levels of aerosols present in the atmosphere in the Kiev region both prior to and during the current, ongoing conflict, is highly significant. Furthermore, this study also highlights the importance of using the Sentinel-3B SYN satellite in a current conflict zone where the entry of civilians is prohibited, enabling the detection of aerosol levels in what may be otherwise inaccessible territorial regions [4][5][6].…”

“…Thus, the segmented images in Synthetic Aperture Radar (SAR), with deep sampling of specific super pixels allow for geospatial studies containing smooth graphical representations. Studies involving atmospheric pollution, when related to aerosol analysis, demonstrate the predominant presence of nanoparticles and fine particles, <1 µm in aerodynamic diameter, capable of remaining suspended in the atmosphere for a long period, as they possess better densities in the particulate structure [4][5][6]. Aerosols are nanoparticles or ultrafine particles in solid or gaseous state present in the atmosphere, originating naturally or artificially, potentiating air contamination with concentrations of different types of chemical elements, and some are harmful to human health, capable of compromising the environmental quality of terrestrial ecosystems [7].…”

“…Aerosols are able to become and remain suspended in the air for extended periods of time as they have low densities [4][5][6]. Injected into the atmosphere through soil movement/disturbance or gas release, a soil with radioactive components allows the accelerated release of dangerous elements that could be suspended in the air by wind or vehicle movements, bringing risks that could be serious to human health, even over a relatively short period of exposure [19,20].…”
