[Scientific and methodologic basis of a program for occupational control of ambient air quality within a totally sanitary protective zone at an industrial center borderline (Permsky area experience)].

The authors suggested and tested an algorithm to select optimal placement of stationary and mobile points for controlling ambient air quality on borderline of united sanitary protective zone of industrial center. The method involves claster analysis to outline sites even in levels and lists of parameters, on borderline of united sanitary protective zone of industrial center. Informative value of the occupational control parameters is evaluated through conjugated analysis of general level of surface concentration of admixtures and enterprise's contribution into pollution. For each enterprise, separate control program is provided. Tests of the method demonstrated that it is effective and conclusive in formation of minimally sufficient programs for occupational control in complicated conditions of industrial centers with single-field enterprises, when industrial releases are close in composition and in created pollution level.
