Emise tuhých znečišťujících látek v chovu hovězího dobytka
PETR, Jan
In this thesis there are presented the values of air pollution by separated solid pollutants of size 10 microns (PM10) in carrying out almost daily activities in selected areas of the two stables, which one of them is based on the economy of manure and the second one is based on housing on the deep bedding. The measurement was done in two selected entirely different stables with different ways of breeding of cattles and different technological processes and expected differences in the values of airborne dust. The measured values and the comparison of the results show that several factors have influence on air pollution in stables. The main factors are the way the technology is used in the stables, the type and characteristics of bedding, difference of work of individual machines and other significant factor is the total transit time of mechanization through stables.

Rating mass concentration of airborne dust in road transport, depending on the amount of traffic and the environment
NOVOTNÝ, Jiří
The aim of my bachelor thesis was to assess the weight concentration of airborne dust in road transport in dependence to traffic intensity and environment. The measurement was performed on class 1, 2 and 3 roads. One to five vehicles following one another were measured on each road class, which simulated the traffic intensity. The measurement has shown that occurrence of airborne dust particles is many times higher on lower class roads than on the class 1 road. Several factors affect the resulting carriageway pollution. The road dirt level and character, intensity of traffic, choice of vehicle track as well as dirt location on the road are the main factors.

Rating mass concentration of airborne dust in road transport depending on the speed of vehicles
PÍŠEK, David
This thesis focuses on an evaluation of the mass concentration of airborne dust in road transport in relation to the speed of the vehicles. Initially described are airborne dust, its types, fractions and impacts on humans and living environment. Furthermore, the work devotes itself to the measures taken against dustiness, the effects and impacts of transport on living environment and the closely related EURO European emission limits. Part of the work also includes a description of the DustTRAK II 8530 measuring device and individual measurements of dustiness of fraction size 10 m (PM10) during the movement of two vehicles of different weights on selected transport routes. The values measured and their analysis show that the size of the dust matter concentration in the atmosphere is affected by several factors. The main factors are the level and nature of pollution and the type of transport routes, the intensity of traffic, the speed of passing vehicles, the chosen track of passing vehicles in the traffic lane and the distribution of dirt on the road.

Map dust loads of road transport on the environment.
HANŽL, Jaromír
In this thesis, the main objective of implementing mass measurements of airborne dust in the road, depending on the traffic environment and obtain objective information about the actual performance of vehicles in road traffic on air pollution by emissions from non-combustion processes.
