Abstract:

The comparison of experimental and calculation data on concentrations of aerosol, fallen on snow in the vicinity of Heat Power Station-2 (HPS-2) of Barnaul are presented. The scheme is presented of the fallen coal ash distribution at the territories of residential settlements and industrial area of Barnaul, as well as its northeast vicinity (including Ob' river), g/m². A simple universal 3D time-dependent model is used for calculating atmospheric aerosol transport and its fallout on the underlying surface. The model is based on the solution of the semiempirical equation of aerosol advection and admixture diffusion, accounting for its interaction with the underlying surface. The pollutant concentration in the atmosphere and quantity of the particles (or mass) fallen on the unit area of the underlying surface during winter are calculated. It is shown that the difference between theoretical and experimental data does not exceed 24%.
