| Özet: | Title screen Based on field studies of the snow cover and systematization and analysis of scientific data and technical literature data, the distributions of fluorine, sodium, and lithium, as elements included in the raw materials used for aluminum production, in the snow cover in areas proximal to Siberian aluminum smelters were considered. The results showed that the changes in concentrations of fluorine, sodium, and lithium in the snow cover near various plants have the same dispersion pattern, which can be described by an exponential relationship. Exponential relationships of diminishing concentration with distance from the emission source had high correlation coefficients. From the examples established by these relationships, an assumption was made that the behavior of these aerosols in the atmosphere is determined by the general physical and chemical properties, irrespective of the technologies and natural climatic regions of the plant locations. It is suggested that deposition of aerosols from industrial aluminium production can be achieved at a minimum distance from the plants or within the plant area through particle enlargement by various technological methods in aluminium production or by changing the atmospheric scattering capacity Текстовый файл |
