Design of the methodology of measurement for evaluation of filtration efficiency of portable air cleaners and purifiers
Dvořáková, Michaela ; Bělka, Miloslav (referee) ; Lízal, František (advisor)
This work focuses on the research and comparison of several types of air purifiers. It clarifies the principles of filtration and describes the basic types of air purifiers. Part of this work is designed methodology of measurement for comparison of filtration efficiency and filtration rate. The experimental part of this work contains the measurement and comparison made for two types of air purifiers. Selected purifiers were De’Longhi AC230 with mechanical filters and ionic air purifier Ionic-CARE Triton X6. Within the framework of this work an experimental set-up was constructed in the home environment for the simulation of real conditions for the function of the air purifiers. The measurement results provide information about aerosol number concentration process during the measurements and evaluation of filtration efficiency of air purifiers.

Exposure to Nanoparticles in Means of Transport
Maslonková, Ivana ; Kadlec, Radek (referee) ; Adamec, Vladimír (advisor)
The diploma thesis deals with the exposure of nanoparticles in means of transport. The diploma thesis provides an overview of the current state of exposure to nanoparticles in vehicles that people use every day travelling to work. Moreover, the work describes the health risks that can be caused by these particles and have an adverse effect on human health. The work processed data (particle number concentration, particle size and LDSA) which monitored the exposure of nanoparticles in the tram of public transport in the city of Brno and the extent of pollution by nanoparticles at stops.
