five and PM10 concentrations are measured as typical per hour and for each 24h. When the AQI benefit is calculated for each 24h, then SO2, NO2, CO, PM2.5 and PM10 concentrations are calculated as typical for every 24h, when O3 concentration is calculated as the maximum 1h typical and the most 24h shifting ordinary. The IAQI of every pollutant is calculated In accordance with a formula released from the MEP.[19]
