[1] Nikolai K., Gennady G. Prediction of mobilization and sedimentation of natural and anthropogenic dust on the example of moscow territory // III International Conference DUST 2018 SCIENTIFIC RESEARCH ABSTRACTS. — Vol. 8 of Atmospheric Dust. — Digilabs - Bari, Italy Bari, Italy, 2018. — P. 89–89. Dust atmosphere pollution has a special way affects in megacities, reducing air quality, reducing the transparency of the atmosphere, changing the temperature background, has a negative impact on human health and toxicology on plants. Currently, when more than half of humanity live in cities, identifying sources, predicting the mobilization, transfer and sedimentation of dust is one of the key moments in the cities’ ecology. We investigated the feasibility of using the theory of wind erosion created in the framework of the laws of mechanics of multiphase media by Gendugov V.M., Glazunov G.P., in modeling the prediction of dust mobilization / deposition, using the example of urban environments in Moscow city. During this work were determined the values characterizing the mobilization activity of possible dust sources - Uk min, r*, K**, f and Uk, α, Bk. Where Uk min, r*, K**, f - the fundamental indicators of the anti-deflation resistance of soils and grounds and Uk, α, Bk - parameters of zero-model of soil and grounds blowing in an air-dry state. It was first time determination of these parameters for soils and grounds at Moscow territory. All these parameters can predict the emission of dust (kg*m2/c).
