Air pollution is one of the areas that needs to be paid due attention, especially because of the negative impacts on human health. Air quality is affected by a number of factors, especially the production of emissions during combustion processes in industry, transport, but also household heating. Local furnaces are among the most important sources of air pollution in the Czech Republic by aerosol particles (PM) and polycyclic aromatic hydrocarbons (PAHs), including benzo(a)pyrene, both of which are pollutants with serious impacts on human health.

Households participate in emissions of PM2.5 from 71% and from benzo(a)pyrene emissions even 98%. The maximum permissible concentrations of PM10 and benzo(a)pyrene are defined by legislation, Act No. 201/2012 Coll., on Air Protection, as amended. For the above reasons, the concentrations of these pollutants in the air are monitored on a long-term basis within the State Air Pollution Monitoring Network (SSIM) operated by the Czech Hydrometeorological Institute (CHMI). However, this network does not cover the entire territory of the Czech Republic or the South Moravian Region. In the town of Tišnov there is not a single station for long-term measurement of air quality. For this reason, the Transport Research Centre has started work on the project Design and implementation of a network for air quality measurement in the city of Tišnov" supported by the SGS-2 call "Svalbard" from the program "Environment, Ecosystems and Climate Change", financed by Norway Grants, in order to determine the concentrations of aerosol particles of PM10, PM2.5 and PM1 fractions in the territory of the town of Tišnov.

The project will run from July 2023 to April 2024.

What is the aim of the project?

The aim of the project is to determine the concentrations of aerosol particles of PM10, PM2.5 and PM1 fractions in the territory of the town of Tišnov, to identify areas with increased concentrations of these pollutants and to identify possible sources of pollution (local furnaces, industry, transport). As part of the project solution, measurements will be carried out using low-cost sensory units at 8 locations in the city. The measurement will be carried out within 8 months (August 2023 – March 2024) in the form of uninterrupted continuous measurements at all locations.

Where will the measurement take place?

Environmental experts from the Transport Research Centre will carry out detailed measurements and evaluation of concentrations of aerosol particles of PM10, PM2.5 and PM1fractions at selected 8 localities in the town of Tišnov.


The measurement will take place continuously for 8 months at 8 locations in Tišnov. The start of measurement is set for August 2023, the end of measurement for March 2024. During the measurement, continuous concentrations of aerosol particles will be monitored, including measurements of meteorological parameters (temperature, humidity, atmospheric pressure, wind direction and speed).

How were the sites chosen?

The sites were selected for the purpose of blanket coverage of the town of Tišnov so that it was possible to characterize individual parts of the city in terms of aerosol particle concentrations. Locations were selected both on the outskirts of the city and in the center. The sites were selected in such a way as to cover areas with various presumed sources of pollution, including local furnaces, in cooperation with city representatives.

Cooperation with the municipal authority

Representatives of the city from the relevant environmental department are also involved in the project, especially in the selection of suitable locations. They know the local situation and have many years of experience with implemented activities related to air quality.
