Abstract: The article gives a brief description of different approaches to assessing the total contamination of the depositing environments. Presents the main disadvantages of the conventional ratio of total pollution of soils to assess changes in the ecological situation in terms of local pollution vastly different risk and content of the contaminants. The urgency and the possibility of using the updated total contamination factor from the point of view of the theory of information transmission; presents the ranking updated total pollution index for different numbers of priority contaminants. A comparative analysis of environmental assessment of the urban territory with the use of classic and refined rates of pollution. The coefficients calculated for the various functional areas of large industrial center, subject to significant anthropogenic impact from the side of the airfield and test complex of launch vehicles. The coefficient calculation conducted on the basis of11-years environmental monitoring of priority contaminants (kerosene, heavy metals, formaldehyde, nitrates). The conclusion about the necessity of calculating the updated total pollution index of soils is provided, as a more accurate, informative and sensitive to changes of the environmental situation in terms of a variety of contamination depositing environments of large industrial centers.

Key words: integral index of pollution adjusted index of pollution the total rate of pollution soils urban areas environmental monitoring contaminants
