ESTIMATION OF CONSEQUENCES OF HARMFUL SUBSTANCES BLOWOUT DIFFUSION IN ATMOSPHERE ON THE BASIS OF METHODOLOGY TOXI-3 SOFTWARE IMPLEMENTATION
Glukhov S., Gendel G., Kleimenov A.
-3 . , , , , . , . .
The present computer programs on TOXI-3 methodology have a number of disadvantages. For example, it is impossible to determine the concentration of harmful substance on a concrete maps point, there is no binding of objects to a map. Therefore we designed the original computer program, in which all these disadvantages are removed. The program allows to describe adequately processes of harmful substances diffusion in atmosphere and can be utilized in the field of industrial safety security problems.

PHYTOEXTRACTION OF MINERAL FUEL COMBUSTION PRODUCTS HEAVY METALS FROM SOIL
V. Bashkin, R. Galiulin, R. Galiulina

. (). . .
In conditions of vegetative experience the potential of extraction by Indian mustard from soil of copper and nickel as possible products of mineral fuel combustion is stimated. For acceleration of phytoextraction process ethylenediaminetetraacetic acid (EDTA) into soil was brought. Frequency rate of crop and cultivation of Indian mustard and use of EDTA allow to reduce considerably time of soil purification from heavy metals. Emergency in field approbation of phytoextraction in regions with high aerotechnogenic loading is emphasized.

Distribution of arsenic as product of mineral fuel combustion and cancerogenic substance in soilplantwaterbottom sediment system in the territory of Chelyabinsk city and its environs is estimated. The waterway of arsenic entering the environment is established mainly. Increase of arsenic content in soil, water and silt on a course of the Miass river draining the researched territory testified to functioning of dot sources of pollution by substance of the environment. Necessity of urgent elaboration of preventive and remediation measure system on decrease in arsenic influence on the person through atmospheric air and trophic chains is emphasized.
