The project "Monitoring and Measures to Improve Air Quality in the City of Brno" within the Tromso Call is implemented by the Faculty of Economics and Administration of Masaryk University as the main investigator in cooperation with the City of Brno. The project is an example of linking applied research at the academic level with the practice of development and implementation of specific measures at the local level by the city. At the same time, it connects the field of natural sciences and humanities, using the example of air pollution and its impact on the health of inhabitants according to their behaviour.
The recent period related to COVID-19 has produced very interesting results regarding changes in the immission concentrations of the load of different air pollutants. It was confirmed at many sites that radical reductions in traffic intensity on roads also led to substantial decreases in NOx immissions. However, PM10 or PM2.5 in particular, did not correspond to this development. In many places, on the contrary, these types of immissions have even increased in the course of strict mobility measures (adopted gradually at the European or even global level). For this reason, a key question has arisen as to the accurate sources of this immission load, including the identification of the degree of influence of various specific factors such as the type of development, meteorological and relief conditions, and the type of use of the area as residential, recreational, transport, industrial or commercial.
The project aims to create an update of the Action Plan for the improvement of air quality in the city of Brno, based not only on certified air quality measurements with double density compared to continuous measurements), but also on the measurement of the air pollution burden of residents concerning their traffic behaviour. This corresponds to the question of whether an individual is able and motivated to change his/her transport behaviour if he/she is aware that changing his/her transport mode significantly impacts his/her health.
