Airborne fine dust particles (FD) are recognized as one of the most harmful pollutants to human health. The size of fine dust determines their ability to penetrate the human body, and particles less than 10 microns in size are recognized as the most dangerous. At the same time, the causes of FD toxicity are still insufficiently studied. For example, the relationship between mortality from COVID-19 and the concentration of FD in the air was shown. However, it is still not clear whether fine dust is a direct vector carrier of the virus or only exacerbates the susceptibility of the human body to the virus.
