Introduction At present time even more attention is paid to the effect of long-range transport of continental atmospheric aerosol (AA) to the Polar region. The studies in Norway and Alaska have shown, that Western and Central Siberia may considerably contaminate the atmosphere in Arctic. The cities and many regions of Southern Siberia are strongly contaminated by industrial emissions.
In many cases such powerful point sources of polluting industrial emissions are rather simple for chemistry of an environment and one can expect the obtaining of important scientific results with minimum charges. Simultaneously in Siberia we have remote areas, which are located at huge distances from industrial, highly polluted centers. According to generally accepted opinion, the characteristics of aerosols in these regions are considered to be “background”, this mean aerosols, which are formed due to natural processes, with low influence of polluted substances. Many years of studies of characteristics of atmospheric aerosols in different regions of Earth show, that considerable part of aerosol mass are particles, produced due to wind erosion from the surface of soil and oceans. These are so- called dust and sea salt particles or coarse fraction AA (d>1mkm). The content of particles fine fraction AA (d<1 mkm) of natural and anthropogenic origin is rather low. The Central Siberia during winter period is distanced for few thousand km from the sources of erosion particles. In winter, the earth in Siberia is covered by snow, and water surface, including ocean, is covered by ice. Therefore, during winter, the conditions are rather favorable for studying of long-range transport of industrial pollutants. Introduction
The monitoring aims Investigations of laws of formation, transformation and transport of aerosols in Siberian region at local, regional and global scale for determination of their sources and sinks. Estimation of influence of AA on quality of atmospheric air, levels of contamination of vegetation, soil and water, fate of different substances and elements in objects of environment. Estimation of an impact of AA of different nature onto people’s health and animals. Investigation of AA influence onto atmospheric processes and climate.

The integrate monitoring AA in Siberia was organized. This one permit to determinate the AA microphysical characters and its spatial-temporal change local, regional and global scales. There was organized the information collection that need to design data base and the evaluation of technogenic impact on different biosphere components and health people. Summary Summary
