Estimate of air quality in valleys of Yegoshikha river and Danilikha river

The quality of air is the main issue that humankind faces every day. It is an essential aspect of health of the population. The objectives of this research are to determine what pollutants are the most significant and what sources of pollution are the greatest emitter in Perm. Data for this study comes from national net of measurements of air pollution of Rosgridromet and researches of air quality in different areas of Perm. There has been quantitative analysis of results of measurements that was hold close to valleys of minor rivers Danilikha and Yegoshikha in this study since 2016 to 2022. Air quality was estimated by comparing measurements of concentration of chemical substances with established hygienic standards. The analyzed data show that the main pollutants in air of Perm are Formaldehyde, Nitrogen Dioxide, Phenol and Ethylbenzene. Exceedances of maximum one-time concentrations of all significant pollutants were identified. Exceedances of daily mean concentrations of formaldehyde were observed during all the period of study. A possible explanation for presence of pollutants might be that burning of fossil fuels by transport and by fuel power industry, by impact of mechanical engineering plants. The results of this study indicate that the national net of measurements is non-effective and does not give enough information for estimation of air quality in Perm. We need to measure more pollutants, and to have more monitoring sites to determine the air quality and the impact of transport or industry or other sources of air pollution on human health.
