TO THE ISSUE OF PRACTICAL IMPLEMENTATION OF THE REQUIREMENTS FOR DETERMINING THE LOCATIONS OF AUTOMATED POSTS IN THE ATMOSPHERIC AIR MONITORING SYSTEM OF TECHNOGENICALLY INSTALLED URBAN SYSTEMS

Abstract

Purpose. The results of theoretical and analytical-calculation studies on the substantiation of the automatic stationary post location of constant control (PCC) in the zone of probable influence of the industrial enterprise PJSC «Kryvyi Rih Cement» (Kryvyi Rih) with the determination of the expected contribution of this object to the general atmospheric air pollution level. Methodology. The requirements for the organization of observations of the atmospheric air state and the specific choice of stationary sampling points are generalized. Method of calculating the scattering of pollutants is used. Results. A set of indicators and characteristics that affect the processes of atmospheric air pollution formation in the area of the probable negative impact of the industrial facility is determined. The conditions of PCC location are detailed specifically for the conditions of technogenic loaded urban systems. On this basis, a priority place for the installation of a stationary automated post of constant control and monitoring of air pollution in the area of the industrial enterprise PJSC «Kryvyi Rih Cement» influence has been specified. The calculation of the scattering of pollutants in the surface layer of the atmosphere using the software package «EOL +» to determine the expected level of pollutants concentrations present in the emissions of the object at a certain PCC location, as well as at the SPZ to determine the expected maximum contribution of this object to the overall level of air pollution. The maximum expected calculated values of surface concentrations at the location of the PCC are from 0.01 for sulfur dioxide to 0.21 MPa for the summation group № 31. Originality. The requirements and conditions of the automated monitoring stations location in the areas of the negative impact of industrial facilities are summarized, which allows to clearly and reasonably determining the priority location of the control panel. Practical value. The results of the research have been practically implemented. The control panel has been installed and is working successfully, as evidenced by the data of the city web portal «Ecomonitoring» in Kryvyi Rih – https://www.krmisto.gov.ua/ua/rc/ecomon.html. The social significance of the research is both in the participation of the industrial facility in the system of automated observations and assessment of air quality and in informing the inhabitants of man-made urban systems on the environment state.
