“…It has been pointed out that aerosols with high hazards to human health, in the form of nanoparticles and ultrafine particles, are mostly of metallic origin [12], such as arsenic (As), chromium (Cr), nickel (Ni), and manganese (Mn), contributing to the carcinogenic risk to the population in different age groups. It is worth considering the presence of radioactive aerosols suspended from the atmosphere, generated by nuclear installations, capable of releasing ultrafine particles of 0.01-0.1 µm in aerodynamic diameter, with a high degree of harm to human health [13]. Some pollutants, produced by chemical reactions, such as PM 2.5 and PM 10 particles, sulphur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), nobelium (NO) and ozone (O 3 ), are present in high amounts in the atmosphere, requiring constant measurements [14].…”

The use of images from the Sentinel-3B SYN satellite (surface reflectance and aerosol parameters over land) is currently one of the most advanced technologies utilized to identify atmospheric aerosol concentrations on a global scale. The general aim of this study is to analyze the evolution of aerosols in the atmosphere of the Kiev region in northern Ukraine during 2019, 2020, 2021 and 2022. Due to this study’s timing, both prior to and during the current military incursion into Ukraine, this study also evaluates the consequences of the invasion of the Russian army on the territory of Ukraine, in relation to the quantitative levels of aerosols present in the atmosphere. Satellite image data were modelled in SNAP software (Sentinel Application Platform). Using the JASP software (version 0.14.1.0), clusters with variations of T550 (Aerosol Optical Thickness) were generated. The Sentinel-3B SYN satellite images were made available by the European Space Agency (ESA), with moderate spatial resolution (>300 m), calibrated and normalized to an average standard of 0.83 µg/mg, with a maximum error of 6.62% in the 30 sampled points. Satellite image data were modelled in SNAP software. Using the JASP software (version 0.14.1.0), clusters with variations of T550 (Aerosol Optical Thickness) were generated. The results show variations in the concentration of T550 in different periods, revealing that the military conflict between Russia and Ukraine directly influenced the dynamics of aerosol concentration, attributed to factors incompatible with environmental sustainability.
