In 2022, there was no detected exceedance of the permissible levels of nitrogen dioxide (NO2) as determined for health protection criteria. The global carbon dioxide emissions from fossil fuels are likely to increase by 1.0% in 2022 compared to 2021. The permissible values for sulfur dioxide, nitrogen dioxide and nitrogen oxide, as well as dust and lead in the surrounding air were set in the Journal of Laws, L 163. Sensors monitor the levels of nitrogen dioxide (NO2) emissions, while those further from the streets measure ozone levels. Although the air quality is improving, the issue of air pollution still persists. The main sources of carbon monoxide and volatile organic compounds (VOCs) emissions are primarily from transportation. The levels of nitrogen dioxide and nitrogen oxide are combined for calculation, as well as the sum of metal and its compounds in suspended dust (PM10), and the concentration of dust. Acidification of the air is closely related to the presence of acidifying substances such as sulfur dioxide, nitrogen oxides, ammonia, and dry particles. Areas with an average July air temperature above 30 degrees Celsius are marked in dark orange, and they are mainly affected by traffic-related pollution responsible for emissions of nitrogen
