Berlin - In Germany, pollutant limit values were exceeded in 65 cities last year. The city with the highest pollution, especially from diesel exhaust, is still Munich, followed by Stuttgart and Cologne. This was announced today after the final evaluation of the measurement data.
A preliminary evaluation in February showed that the limit values were exceeded in 66 cities. Remscheid has dropped out of the list - the limit values are now observed there. In 2016 there was still higher air pollution in 90 cities nationwide than legally permitted.
The first driving bans for older diesel cars came into effect in Hamburg today in force nationwide. Two heavily trafficked street sections in the city center are affected. Hamburg wants to achieve that the nitrogen oxide pollution in the air decreases. The limit value for exposure to harmful nitrogen dioxide (NO2) is 40 micrograms per cubic meter of air.
In 2017, an annual mean of 78 micrograms of NO2 per cubic meter was measured in 2017, in Stuttgart 73 and in Cologne 62 micrograms. This is followed by Reutlingen with 60 micrograms and Düren, Hamburg and Limburg with 58 micrograms of NO2 each.
