The ecological situation in industrial regions causes a growing anxiety among the population. Besides, it is necessary to understand that any attempt to change the ecological state by means of changing the technology of the production itself entails finally a disturbance of an established balance of the technological process condition and of the working-place ecology. Any change of this balance must be controlled and its consequences predictable. Therefore, investigation of a region's ecology, establishment of relationship between a region's ecology and production technology and investigation of sensitivity of disturbance of balance in case of even relativly small chances in technological process must precede any restructuring of production technology. This is connected with the difficulties of establishing a direct definitive link of a region's ecology with some particular type of production, if, of cource, it does not predominate in a considered region. As a rule, the situation in a region is determined by a complex of productions that may differently and in different time influence the ecological situation at a specific place. Therefore, conventional methods of single sampling conducted periodically in different time cannot create an objective situation pattern as technological discharges of production are different during twenty-four hours and months. In this respect, such methods of monitoring are of interest which allow to reveal the dynamics of change of concentracion of harmful substances accumulating in one or another form and aggregate state in an inspected industrial region. This problem is especially urgent for major regions of the counry where the industrial power is concentrated, respectively.
