Control of pollutants in the atmospheric air on the example of an automated monitoring system in St. Petersburg

Abstract

Assessment of air quality is an integral part of the strategy to improve the quality of life and health of the population. According to the recommendations of the World Health Organization, carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone, and particulate matter are subject to monitoring. Of particular interest are nitrogen oxides and ozone, which are characterized by an inverse correlation. The study is aimed at establishing the degree of this relationship according to the data of an automated monitoring system and assessing the level of air pollution in St. Petersburg, Russia. In addition, it is necessary to control the content of various specific compounds, including volatile organic compounds (VOCs). This is because public health impacts include exposure to both the VOCs themselves and secondary air pollutants resulting from chemical reactions between VOCs and other components. Thus, these substances are constantly monitored at observation stations in St. Petersburg. VOC monitoring provides for qualitative and quantitative analysis on measuring equipment with preliminary sampling and their preparation. Sampling uses various methods and devices. Based on the results of the theoretical and experimental studies, the authors propose the use of sampling devices, which differ from analogues in their design, metrological and operational characteristics.
