It is well known that industrial centers are powerful sources of emission into the atmosphere of lot of pollutants transported with aerosol particles. As a result, the formation of antropogenically changing bio-geochemical provinces takes place. There are some examples of air pollution investigations in the vicinity of industrial centers, but unfortunately the quantitative regularities of these processes are not very well studied. There are a number of difficulties concerning mathematical description of the aerosol particles transport to provide the detailed picture of pollutant distribution.

According to the problems mentioned above it seems reasonable to distinguish the processes of local and regional transport. To describe a local contamination picture, the geometry of the source, the wind speed, and the vertical turbulence characteristics, a uniformity of the ground surface, etc., should be taken into consideration. However it has been shown, using theoretical and experimental data that for a weakly sedimentated impurity being removed from a pollution source at distances of 7-10 km these factors practically do not influence the deposition processes independent of the height. Therefore the non-sedimentated impurity transfer at the regional level may be described using a minimum number of parameters.
