Assessment of the influence of geophysical parameters on the value of maximum surface concentrations from emissions of asphalt concrete plants

Abstract

The influence of geophysical parameters of the coefficient of temperature stratification of the atmosphere and terrain, as well as climatic characteristics on the maximum values of surface concentrations of emissions into the atmosphere is analysed. The results of the presented material make it possible to predict atmospheric pollution by emissions coming from asphalt concrete plants. The paper presents a comparative analysis of the inventory data of the ACP of six cities of the Russian Federation (Perm, Temryuk, Kursk, St. Petersburg, Kaliningrad, and Novgorod); calculations of gross emissions made by specific indicators for all ingredients: dust, carbon monoxide, nitrogen oxides, petroleum hydrocarbons, and sulfur dioxide. The dependence of the maximum surface concentration of a harmful substance on the coefficient of temperature stratification of the atmosphere and the dependence of the maximum surface concentration of a harmful substance on the terrain coefficient are established. There is a significant difference in annual emissions into the atmosphere in different regions with the same productivity and efficiency of treatment systems. The difference in the technogenic load on the environment from the geophysical characteristics of the region is revealed. The significant influence of the geographical location of Russian cities on the norms of maximum permissible emissions and the parameters of their dispersion, in particular, on the maximum surface concentration, is presented.
