Information about harmful substances emissions from stationary sources can be found on the following link

There are two types of identifiers on the map. They reflect the location of ambient air quality monitoring places.

Air quality monitoring stations

The colors match the air quality indicator in the monitoring hour. It should be noted that the average annual rate of air quality is not reflected, which is significantly different. The measurement of the six main contaminant sample data is determined by the level of the index, which reflects the current state of air quality at each monitoring station. The index determines the level of pollution for six pollutants according to the following scheme.

(CO concentration mg/m³, concentration of other pollutants µg/m³)

Pollutants	Good	Fair	Moderate	Poor	Very Poor
PM2.5 Particles less than 2.5 µm	0-10	10-20	20-25	25-50	50-800
PM10 Particles less than 10 µm	0-20	20-35	35-50	50-100	100-1200
NO₂ Nitrogen Dioxide	0-40	40-100	100-200	200-400	400-1000
O₃ Ozone	0-80	80-120	120-180	180-240	240-600
SO₂ Sulphur Dioxide	0-100	100-200	200-350	350-500	500-1250
CO Carbon Monoxide	0-5	5-7	7-10	10-15	15-50

Note* Data received from automatic air quality monitoring stations is not verified. Verified data is available in the reports.

Gray color indicates, that there is not enough data to generate index for chosen period.

By clicking choosing specific station, there is button “Detail Information” that shows graphs with the same color as index tables. First graph shows the aggregated values of data recorded in the last 365 days of the observation. The XY axis of the second diagram presents evolution of the index for various pollutants during the last 1 month. Concentrations for that diagram are normalized on average means.

Value of given pollutants are calculated with following methodology:

The hourly concentrations of CO and O3 are the average value of the last 8 hours concentrations, as for PM10 it is the average value of the last 24 hours. The concentration of the lead is based on the calculation of the mean value of the last 12 months. Hourly data will be displayed with 10 minutes delay.

Places of indicative measurements

The colors correspond to the air quality index for the given period and values of indicative measurements. The index determines the level of pollution for five pollutants according to the following scheme.

(Concentration of pollutants µg/m³)

Pollutants	Good	Fair	Moderate	Poor	Very Poor
NO₂ Nitrogen Dioxide	0-26	26-40	40-100	100-200	200-1000
O₃ Ozone	0-80	80-120	120-180	180-240	240-600
SO₂ Sulphur Dioxide	0-50	50-125	125-350	350-500	500-1250
C₆H₆ Benzene	0-2	2-5	5-7	7-10	10-12
PB Lead	0-0.02	0.02-0.1	0.1-0.5	0.5-1	1-10
