The German environmental aid (DUH) strikes again exhaust Alarm: On Wednesday, the Association released the results of a measurement campaign, 47 particularly sensitive locations in Berlin, the loading of the air with nitrogen dioxide (NO2) was measured for four weeks in the autumn, around kindergartens, schools, doctor’s offices and nursing homes. So given that, where particularly sensitive people.
more than half of the measurement locations has been exceeded, according to the DUH the legal limit of 40 micrograms of NO2 per cubic meter of air. To nursing homes as well as schools and day-care centres there were in the Mediterranean 41 micrograms to doctor’s offices and hospitals, 45 micrograms. The highest burden was measured with 57 micrograms in front of the entrance to a children’s physician at the Kaiser-Wilhelm-Platz in schöneberg. In front of a kindergarten in the Central market street in Reinickendorf, there were 53 micrograms, in the case of a seniors care facility in Weißensee 48 micrograms.
For DUH managing Director Jürgen Resch, is to show the results, “we have in Berlin a nationwide Problem with the diesel exhaust toxic nitrogen dioxide”. In the face of 250,000 asthmatics – including 50,000 children – in the capital of the load is unacceptable. According to the DUH-cited children’s doctor, Christian Döring, the bad air can damage children permanently. The threat to start already in the womb.
environmental management: Not a Surprise for DUH-measured values
the DUH was Measured according to own statements with so-called Passive samplers in two meters height. Such collectors are also part of the measurement network of the Berlin environmental administration, and to determine, in many places, in the main road network similar to high loads. This is also why the speed limit is 30 on Potsdamer Platz and the main road to the Kaiser-Wilhelm-Platz recently.

to order An expert of the Federal environment Agency of DUH looks in the measured values, is no Surprise and underlines at the same time, their limited significance: “In the case of series of measurements of a single month, the weather can have conditions such as air currents and rainfall has a strong influence on the results. Therefore, only the annual average is really meaningful.“ Berlin belong to the cities, which were relatively good about the air pollution in the streets in the picture. The largest proportion of NO2 from diesel-coming vehicles, was established.
The DUH-measurement results are also enjoying from the view of the Berlin environmental administration with caution: passive collectors were significantly less accurate than the measurement container and to understand, therefore, rather than orientation. Added to this is the short measurement period. In addition, the environment is measured the help of a lesser amount than the Senate, the to install its passive collectors for protection against vandalism in three and a half meters in height. Below the pollutant concentration has to be higher. Permissible measuring heights between 1.5 and four meters.
these limitations aside, the results of the DUH in the expected range and so high, “that there is an undisputed need for action”. The administration was working “feverishly on a new version of the clean air plan in order to bring the nitrogen oxide values in the limit values”.
