Abstract / Résumé : Possible negative effects of these air pollutants can be assessed using the legal standards and critical levels. We analysed 7 years of daily measurements of sulphur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM10) and ozone (O3) at the forest ecosystem research site in the region of Bílý Kríž. The annual average for the studied period was 24.0 µg m-3 for PM10, 9.4 µg m-3 for NOx and 12.0 µg m-3 for SO2. The daily values exceeded 50 µg m-3 for PM10, 125 µg m-3 for SO2, 65 µg m-3 for O3 on approximately 5.6, 0.0 and 34.3% of cases, respectively. We found a decrease in SO2, NOx and PM10, but some days and years registered the values higher than the standard limits. Most of the observed decrease for sulphur dioxide is due to the reduction of SO2 emission in the Czech Republic. For O3, we observed a significant increase. No trend was identified for NOx.
