Perhaps the most frequently exceeded limit value is the 24-hour limit value for suspended PM10 particles, and this is what we will now focus on. Its value is 50 µg / m3 and this limit is considered to be exceeded in more than 35 exceedances per year. We only included stations with min. 90% of the data for each year to make a comparison (if the station does not have 90% of the data and especially if there is no data from the cold season when the limits are more likely to be exceeded, the number would be biased).

The following chart shows the number of exceedances of the limit in the five-year period 2015-2019 at stations in Brno (Kroftova and Soběšice stations are missing for 2019, which are manual and data from them are not available).


Several days ago after the lapse of November environmental lectures in Brno, Czech Republic, record of those lectures now is available in the web to watch. It was a very good lectures, which depict  BRNO and whole Czech Republic air pollution issues, highlight corner questions about the ways how to improve the situation with the air quality, main sources or pollutants and characteristic of the pollutants itself. During the last lecture it was described health problems caused by bad air quality in Czech Repblic.
