This diploma thesis deals with the concentration of dust particles during harvesting of forage, namely hay, straw and fed forage. The measurements were always carried out on another land in the Vysočina Region. DUST TRAK II 8530 instrument was used to measure dust concentration. Each measurement was performed for ten minutes.

Topic of this thesis is comparsion of emission concetration of solid pollutants in intensive poultry farming with different technologies. Measurement was done in cage system and two alternative poultry housing systems in company International poultry testing based in Ústrašice. For measurement of dust particles was used measurement device DUSTTRAK II 8530, own measurement has been done continuously for 24 hours with record every 3s. Dustiness was tracked in size fraction PM10. This dust particles can negatively influence health of employees and reared poultry. By measuring and following evaluation was found, that lowest value of dust particles was achieved in cage housing system. Considering health protection of employees and requirements for poultry wellfare is necessary keep dustiness of stable enviroment on lowest level.

Intensive poultry farming releases contaminated gases, odors, microorganisms and large concentrations of dust particles. Dust particles have a negative effect on the health of humans and animals. Dangerous particles with a diameter of less than or equal to 4 m, which can travel to the gas exchange area of the human respiratory system, pose a great health risk. The aim of this thesis is to measure PM10 dust particles in intensive poultry farms depending on the age of the chickens. Another goal is to compare the results between farms and compare them with the values shown in Table 5.15 on page 157 of document Final TWG meeting for review of the IRPP (Integrated Pollution Prevention and Control) BREF (Reference Document on Best Available Techniques). The measurements were carried out at the farm Alas a.s. in Hartmanice and at the farm Farma u lesa a.s. in Sudoměřice u Bechyně.

As agricultural production grows, the focus is on improving air quality, which affects not only residents around farms, but also climate change on a global scale. This thesis deals with the measurement of particulate pollutants and odor emissions in intensive poultry farming. The measurements were carried out at the Farma U Lesa in Sudoměřice u Bechyně in the spring and autumn of 2018. The production specific emission of odorous substances into the air was evaluated using dynamic olfactometry according to ČSN EN 13 725, which ranged from 0.01 to 0 according to the fattening cycle phase, 3 OUE. Ks-1. s-1. Compared to the BREF reference document, which lists emission odor values from 0.032 to 0.7 OUE. Ks-1. s-1 the measured values on the farm Mr. Šonky came out very low. Dust particles of PM10 fraction were measured according to the ČSN EN 12 341 methodology for the measurement of dust particles and the production specific emission of PM10 particles was found, which during the whole fattening cycle was measured to a maximum of 0.0025 kg. Ks-1.year-1. The measurement results were compared with the BREF reference document, where the maximum permissible production of solid pollutants of this fraction from 0.004 to 0.025 kg. Ks-1.year-1. In comparing the measured dust emission values with the BREF, the production of harmful emissions was very low.

This thesis was focused on monitoring production of dust particles in poultry farming. This measurement was made with the Dusttrak II 8530 which monitored the environment in the stable every 3 seconds for 24 hours. For monitoring were selected companies in the South Bohemian Region, specifically MTD Ústrašice and Farma u lesa. Results of Dusttrak measurements showed that none of the stables exceeded the permissible limits of dust particles. Additionally microscopic analysis of the samples of dust particles revealed that the main component of source of dust was feed mixture.

The objective of this diploma thesis is to assess the factors affecting the concentration of dust particles during forage pressing. For this purpose, five presses for square bales and five presses for round bales were selected. They were harvesting different kinds of straw. Thanks to measurement using an aerosol monitor, the concentration of dust particles during the harvest was detected. The measured values were evaluated and the amount of concentration of the dust particles between the square and round bale presses was compared. There were also set the methodological steps of the measurement procedure.

Title: Dust trap for light scattering study Author: Petr Bartoň Department: Department of Surface and Plasma Science Supervisor: doc. RNDr. Jiří Pavlů, Ph.D., Department of Surface and Plasma Science Abstract: Light scattering on small grains is common interaction occurring wi- dely in space environments, including Moon surface, dusty nebulas or even the upper atmosphere of the Earth. For experimental measurements of light scatte- ring intensity profiles, we designed and constructed a unique experiment. Using so called acoustic trapping, we are able to capture a single dust grain (or small water droplet) in midair, to irradiate it with the laser beam, and to observe scattered light directly with the photodiode mounted on a precise goniometer. In the thesis, we present not only construction details, but also the first results, which help us to evaluate abilities of the experiment, and provide useful recommendations for further development of all dust-related experiments. Keywords: light scattering, acoustic trap, dust grain, scattering measurement 1

The aim of this thesis is to perform comparative analysis of the state policies of the Czech Republic and Poland aimed at reducing dust emissions from industrial and power generation sources of air pollution in the Moravia-Silesia and in the Silesian Voivodeship. The analysis is meant to facilitate improving the regulation requirements of these sources in both districts. The extent of regulation of the sources of air pollution in the Silesia Voivodeship influences the amount of dust emissions produced by such sources and, due the influence of the existence of cross-border transfer of emissions, this influences the concentration of particulate matter in the atmosphere in the Moravian-Silesian Region. The thesis arrives at the conclusion that the industrial and power generation sources of air pollution in the Czech Republic in the Moravian-Silesian Region faces stricter regulation requirements in comparison with similar sources in Poland in the former Silesian Voivodeship. Stricter conditions of regulation for Czech sources are the reason for the lower level of emissions and the resulting higher control costs such sources. The thesis concerns comparative analysis of the control costs a sample group of metallurgic and power generation plants in the Moravian-Silesian Region and in the Silesian Voivodeship.

This thesis deals with aspects of the dust particles which occur in gaseous products from biomass combustion. The thesis introduces technologies by which solid particles capture from a combustion flow can be implemented. Principles and technical means of dust particles separation in mechanical separators are put in focus primarily. The thesis is concluded with a technical design of a cyclone separator.

Title: Dust - UV interaction Author: Libor Nouzak Department: Department of Surface and Plasma Science Supervisor: RNDr. Jiri Pavlu, Ph.D. Supervisor's e-mail address: jiri.pavlu@mff.cuni.cz Abstract: Micrometer objects (dust grains) are an integral part of the universe. As other objects in the plasma, these dust grains charge to potencial close to the potencial of the plasmas (in this case, interplanetary plasma). In the universe, the photoelectric charging dust grain dominantes all other charging processes. In general, the resulting charge of dust grain is given by a balance of all processes, which haven't been mostly jet theoretically described. In our laboratory, we are simulating space conditions and measure resulting charge and his changes on a single separated dust grain. This work is partly focused to UV source application and to finishing its electronics, and partly on test measurements and model calculations, connected with newly built experiment (e.g., to estimate effects of backgound currents, surfaces, and the geometry of the dust trap electrodes). The work is finished by the first measurements of glass grain charge under electron bombardment with provisional detection optics. Obtained results are compared with previous measurements on the same type of dust grains. Key words: dust, dusty plasma,...
