Green-Zones participates to the citizen science project of air quality measurements “BerlinAiR – NO2-Atlas". Our team deals daily with issues related to environmental zones, air quality and traffic restrictions. For this reason, we have decided to actively support this project. The campaign was initiated by the “Environmental Chemistry and Air Pollution Control “ faculty of the Technical University of Berlin (TU Berlin).
Since mid-January, for 14 days, our sensor has been collecting air samples on the street in front of our office in Berlin Charlottenburg. The sampling is a gas collection.
According to the measurement method, the NO2 is transported to a Plexiglas tube (Palmes’ tube) and stored in it. The upper part of the tube is equipped with a paper filter impregnated with a chemical. This chemical helps absorb molecules from the air that you want to collect.
After the 14 days of analysis, the NO2 concentration at the measurement site will be determined.
After completion of the measurements, the collected results, including the determined NO2 concentration, are inserted into an interactive map on the university's homepage. In this way, interested citizens will be able to find out about the air quality in their neighbourhood, workplace, etc. Participation in this interesting project is of course free of charge. If you are interested, you can actively participate in the measurements and obtain the necessary material from the TU University of Berlin. The sensors can always be picked up from Monday to Thursday between 10 and 11 am and from 2 to 4 pm at the TU-Campus Charlottenburg, Fasanenstr. 1a, KF-Building (opposite VW-Library) in room KF103 (on the 1st floor).
A few questions for the Green-Zones team were obvious:
What can be done to prevent pollution? Are there alternative solutions to traffic restrictions? Do the results of “our” tests from the Charlottenburg office differ from the official measurements?
