Description
The project plan builds on the project from Call 2A "Tromso" from the program "Environment, Ecosystems and Climate Change" financed from Norway Grants (project Detailed monitoring of polycyclic aromatic hydrocarbons in connection with the refinement of the Air Quality Improvement Plan of the Southeast Zone CZ06Z 2020+ (PAUPZKO)). Three 14-day measurements (winter 2022, summer 2022, winter 2023) were carried out at one location in the town of Tišnov (locality at the Smíškova Primary School). The measurement will be carried out using sensor units that allow measuring the concentration of aerosol particles PM10, PM2.5 and PM1, as well as meteorological parameters. Metrological traceability will be ensured in the form of comparative measurement of sensors with reference or equivalent devices (equipment regularly metrologically traced to certified reference materials or calibrated by calibration laboratories) in real outdoor conditions based on colocation. The measurement will take place for 40 days at one of the selected locations within the measuring points in the territory of the town of Tišnov. After the completion of the measurement, the units will be deployed to individual locations that were selected in cooperation with the Tišnov town leadership. The measurement itself will be carried out for a period of 8 months).
Summary of project results
The implementation of the project was important in terms of solving the problem of air pollution in the town of Tišnov. Air is one of the areas that need to be given due attention, especially because of the negative impacts on human health. Its quality is influenced by several factors, especially the production of emissions during combustion processes in industry, transport, and 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. For the above reasons, the concentrations of these pollutants in the air have been monitored on a long-term basis within the Network of State Air Pollution Monitoring (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. There is not a single station for long-term air quality measurement in the town of Tišnov. For this reason, it was important to implement this project. Its aim was to determine the concentrations of aerosol particles of PM10, PM2.5 and PM1 fractions in the city of Tišnov, to identify areas with increased concentrations of these pollutants and to identify possible sources of pollution (local heating, industry, transport).
The implementation of the project took place over a period of 8 months. Nine locations were selected – 28th October Square, Sigmundova Street, náměstí Míru, Smíškova Primary School, collection yard, open-air cinema, private company In-Eko, swimming pool area and reference area - cemetery. Dust measurements were carried out at these locations using low-cost sensor units throughout the project. To set the units correctly, the measurement was carried out with the commonly used measuring equipment at the Smíškova site. After that, the measuring units were placed at the above-mentioned locations where the dust measurement took place. After the end of the measurement, an evaluation of all the data obtained was carried out. Based on the data obtained, possible sources of air pollution in the town of Tišnov were identified. Thanks to the above-mentioned activities, the dust level in the town of Tišnov was determined and its sources were identified. The knowledge gained is important for improving the quality of the environment, especially for the sake of the city''s inhabitants and their health. Based on these results, the city can take measures to improve the quality of life of its residents.
Based on the evaluation of the measured data, the final report of the project was prepared, which includes commented measurement results, including the identification of sources of dust pollution in the town of Tišnov. An interactive map was created on the web interface (ovzdusitisnov.cz), which the city has used and still uses to inform the public about dust levels. The main findings from the evaluation of the measured data were presented to the general and professional public in the form of a press conference. The press conference also included a presentation of proposals for possible measures that the city can apply that will lead to an improvement in the current state of air quality. The project provided accurate information about the state of dust in the town of Tišnov. This knowledge will be used in the future by the city management to introduce measures that will lead to an improvement in air quality. The situation has not yet improved because the project did not include the application of measures to improve air quality.
The project was a follow-up to the project from the call 2A "Tromso" from the program "Environment, Ecosystems and Climate Change" financed from the Norway Grants (project Detailed monitoring of polycyclic aromatic hydrocarbons in connection with the specification of the Air Quality Improvement Plan of the South-East Zone CZ06Z 2020+ (PAUPZKO)). As part of the project, three 14-day measurements were carried out (winter 2022, summer 2022, winter 2023) at one location in the town of Tišnov (location at the primary school Smíškova). Based on the results of this project, it was clear that it is necessary to continue monitoring air quality in the town of Tišnov, especially in terms of dust and monitoring of local furnaces. Therefore, the locations were chosen for the purpose of covering the town of Tišnov. Thanks to this project, problematic parts of the town of Tišnov in terms of dust have been identified. Based on these results, the city can apply measures to reduce dust in the city in the future.
