One of the negative factors that affects human health is dust. Particularly high dust exposure in megacities. There are no unambiguous approaches to solving this problem. A lot depends on the geographical location of the metropolis. Therefore, for each city, it is necessary to conduct personal research on the situation with the formation of dust from various objects in the climatic conditions of the city. In addition, the composition of urban dust is complex, which depends on many factors. In the study, it is necessary to determine the main sources of dust and the possibility of reducing their activity. It is also necessary to establish the nature of the medium (e.g. dispersion system, etc.) in which dust is present. An important point is the chemical composition of the dust. It is especially important to know about the presence of dangerous chemical elements or radioactive particles in it. The paper shows that wind flows on the one hand contribute to reducing the level of dust, on the other hand, when it is polluted, they sharply worsen the environmental situation. In modern cities, a decrease in green spaces, especially trees, is planned. This fact also needs to be considered as one of the options for reducing dust load. Special attention should be paid to the methods of rapid monitoring of the air environment in real time. Their use will help in time to take the necessary measures to block dust sources.
