The objective of this work was to analyze the integral indicators of the air quality assessment and approaches to the definition of the AQI for example PM10, PM2.5.
Materials and methods. The levels of the Air Quality Index are determined based on 24-hour concentrations of PM10 and PM2.5, using methods recommended by the United States Environmental Protection Agency and the European Environment Agency of the European Union. The study used concentrations PM10 and PM2.5, which were received during 10.2017 - 11.2018 at the fixed monitoring station, located at the address: 50, Popudrenko str., Kyiv.
Results. There is no unified integrated indicator for air quality assessment, but in most countries the use of the Air Quality Index is a priority. AQI is a tool for informing the public about the quality of atmospheric air and the associated risks to the health of the population. The AQI levels for a specific pollutant, including PM10 and PM2.5, may vary significantly depending on the indexing approach used. This is due to the variability in the pollutants' concentration ranges that correspond to a respective category of the index.
