Particle concentration measurement by various methods
Kuruc, Jan ; Kalivodová, Markéta (referee) ; Sitek, Tomáš (advisor)
In addition to the gaseous components, the Earth's atmosphere contains solid and liquid particles from various sources. These particles are monitored and examined mainly due to their environmental and health impacts and many methods are used for their monitoring and measurement. The aim of the research part of this thesis is to bring the topic of aerosol particles, namely their division, the methods of formation closer, to indicate the impact of these particles on the environment and human health, and to further describe the measuring instruments used to measure the concentration of fine particles. The practical part of this work is the measurement of particle concentration using the impactor, the monitoring of particle concentrations and other data measured by the Brno-Arboretum measuring station, as well as the subsequent evaluation of the measured and monitored data. The primary output from the almost 18-day impactor measurement is considered to be the total concentration of all captured particles of 11.56 g/Nm. The size distribution of the captured particles is plotted in the graph, as well as the quantities monitored from the station. The data obtained is compared at the end and the links linking these data are given.
The Environmental and Health Burden of Transport and the Possibility of its Reduction in Particular Conditions
Dvořáková, Dita ; Popelová, Barbora (referee) ; Skeřil, Robert (advisor)
Air quality is affected by many factors, one of the most important is transport, especially road transport. In this thesis, the transport intensity is compared with number/concentrations of particulate matter in the air. The evaluation is carried out for days, weeks and months, analyses are focused mainly on Brno. In addition, the particulate matter concentrations are analysed depending on meteorological conditions (temperature). The conclusion is focused on the possible measures which can reduce the impact of transport on air pollution.
Spatio-temporal distribution of atmospheric aerosol in urban and rural environment
Bendl, Jan ; Hovorka, Jan (advisor) ; Mikuška, Pavel (referee) ; Vojtíšek, Michal (referee)
Air quality in Europe remains a significant environmental concern, affecting the health and quality of life of its population. While stationary network ambient air quality monitoring allows for the observation of main trends, it is not fully representative of personal exposure of citizens due to high spatio-temporal variability of atmospheric aerosol. Therefore, highly time-and- space resolved measurements with state-of-the-art instruments and methods are needed to observe the aerosol variability, dynamics, identify hot-spots, and pollution sources, which are necessary for successful targeted mitigation measures. This thesis addresses this gap focusing on the characterization of spatio-temporal distribution of atmospheric aerosol in inhabited environments. Novel mobile measurement systems were developed and employed to investigate diverse environments, including rural, urban and suburban area. Aerosol source-apportionment were conducted, and the toxicological effects associated with these environments were also investigated. A novel mobile measurement system was developed for personal exposure measurements and pollution mapping in urban and rural environments. The system was used to measure air quality in the Munich subway, revealing high aerosol dynamics with significantly higher concentrations of...

Characteristic of aerosol particles in indoor environment of different types of libraries and archives
Mašková, Ludmila ; Smolík, Jiří (advisor) ; Hovorka, Jan (referee) ; Barták, Martin (referee)
Aerosol particles are one of the major pollutants in outdoor and indoor air. Particulate matter (PM) can be harmful for works of art by causing soiling and chemical damage, depending on particle size and chemical composition. This study includes indoor/outdoor monitoring of air quality in five archives in the CR, representing different outdoor environments: Zlatá Koruna (rural), Třeboň (small town), Teplice (industrial area), and two archives (National Library - NL and National Archives - NA) in Prague (large city with traffic). The NL and the archives in Zlatá Koruna, Třeboň and Teplice are only naturally ventilated, while NA in Prague is equipped with ventilation and filtration system. The measurements were performed during 4 intensive campaigns in different seasons of the year at every location. The measurements included particle number/mass concentrations, size distributions and chemical composition. Additional measurements were carried out in 2 museums, a depository, and a church. The aim of this study is to investigate concentrations, sources, and chemical composition of PM in the indoor environment, and to establish the relationship between the indoor and outdoor environment. The results showed that concentrations of fine particles in the indoor environment of the NA in Prague were...
