Assessment of the impact on atmospheric air on the example of the Passenger Carriage Depot Vladivostok enterprise of the Far Eastern branch of the Federal Passenger Company, Vladivostok city

Abstract

The relevance of the topic of the work is to assess the degree of negative impact of the Passenger Carriage Depot Vladivostok enterprise of the Far Eastern branch of the Federal Passenger Company, Vladivostok on atmospheric air. 35 pollutants are released into the atmosphere from the enterprise. The work takes into account 39 sources of atmospheric pollution at the enterprise, operating at the time of the inventory, including 25 organized and 14 unorganized. In order to analyze the amount of pollutants entering the atmospheric air, calculations were performed using a unified program — UPRZA Ecologist version 4.6. Based on these calculations, an analysis of emissions of pollutants into the atmospheric air was carried out. The gross emission of 35 pollutants into the atmosphere is 18,998710 tons/year, including solid 5,055938 tons/year, liquid/gaseous 13,942773 tons/year. Of the 17 solid pollutants, the main share of emissions is 0121 diesel trioxide (iron oxide; iron sesquioxide) and 2902 Suspended solids. Of the 18 liquid/gaseous pollutants, the amount of 3 pollutants prevails. These substances include: 2732 Kerosene, 2752 White Spirit and 0616 Dimethylbenzene (xylene). The largest number of emissions from the enterprise are substances that have an approximately safe level of exposure. Of the pollutants that have an approximately safe level of exposure, the most substances emitted per year are: 2732 Kerosene (direct distilled kerosene; deodorized kerosene), 2752 White Spirit. The purpose of this article is to assess the impact of the Passenger Carriage Depot Vladivostok of the Far Eastern branch of the Federal Passenger Company on atmospheric air.
