The table shows the number of hours of nitrogen dioxide (NO2) exceedance at all the measuring stations of the German States networks and UBA for the current year.
The main sources of the air pollutant nitrogen dioxide are combustion processes in the industrial and energy production sectors, and road transport. Nitrogen dioxide affects the respiratory mucous membrane and influences the respiratory function.
The new low-emission zone made effective in the town of Aachen (Level 3, Baden-Württemberg) in February brings the total number of low-emission zones in Germany to 52.
