QUESTIONS OF ENVIRONMENTAL SAFETY OF TROPOSPHERIC AIR IN MEGAPOLIS
The article presents the results of the monitoring of the total (natural and anthropogenic) concentrations of tropospheric ozone in the conditions of development of the technosphere of the metropolis. The novelty of this work is to identify the possibility of using a transformable tropospheric ozone (natural and anthropogenic) as a tracer gas to monitor the environmental safety of surface air by conducting additional studies, including and beyond the urban areas of the metropolis. The objective of the research is the confirmation of previously obtained patterns of seasonal and diurnal changes in the concentrations and obtaining new statistical data in the region, for further processing and analysis. Identified the factors influencing changes in ozone concentrations. It is established that the concentration of daily values of O3, due to simultaneously proceeding reactions of formation and decomposition, is a complex oscillatory process with uncertain frequency and amplitude in day and night, they are comparable (close values) and depend on the total air pollution. Mathematical modeling of the result of multifactorial process difficult and preferably statistical forecasting. Data for the period 2016-2017 confirmed previously identified based on seasonal and diurnal changes and were used for the statistical prediction of environmental safety of tropospheric air. Determined the prevalence of resistant reactions of ozone decomposition (up to the complete decomposition) on the reactions of its formation in the absence of airflow for sverhuspeshnyh objects of a metropolis (transportation tunnels).
