The conditions for the determination of air pollution index

The calculation of air quality index is based on the assessment of 1-hour concentration of sulphur dioxide (SO₂), nitrogen dioxide (NO₂), ozone (O₃), suspended particles (PM₁₀) and 8-hour running concentrations of carbon monoxide (CO); the calculation considers the possible impact of air pollution on the health of population. The calculation for PM₁₀ uses 1-hour average concentrations because they better reflect the current situation (the limits for 1-hour concentrations were derived on the basis of statistical analysis of 24-hour and 1-hour concentrations).
For information purposes, the last column presents the 24-hour running average concentrations of PM₁₀, which are not included in the calculation of air quality index.

Data for the calculation of air quality index are based on current measurements and they are not verified.
Air quality index is determined for each quantity in the given locality separately; the highest of them is presented.
Air quality index is imaged in case the 1-hour data are available at least for NO₂, O₃ and PM₁₀, if they are subject of standard measurements in the locality.
The term “incomplete data” may indicate that the instruments at the station were under calibration during the respective hour.
