Abstract

The article focuses on a method for ranking the city territory according to the level of atmospheric pollu-tion. Calculations of dispersion of emissions from stationary sources are performed, maximum one-time and average annual concentrations of harmful substances for the city of Nizhnekamsk, which is a large center of the petrochemical and oil refining industries, are determined. Analysis of peak short-term expo-sures is carried out on the basis of maximum concentrations expressed in terms of hygiene standards, reference concentrations for acute inhalation exposure and odor thresholds of substances. Long-term impact analysis is based on the Integrated Air Pollution Index. Based on the results of the calculation of these parameters, the zoning of the city'territory is carried out.
