Měření emisí zápachu a tuhých znečišťujících látek z intenzivního chovu drůbeže
 BELKA, Daniel
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.

Emissions of particulate matter in poultry farms
 VACOVSKÝ, Miroslav
Among the considerable factors in poultry include climatic conditions, where the breeding takes place. This work focuses on the content of solid particles PM10 and PM2,5 occurring in this environment. These particles can negatively affect the health status of breeding and staff, ensuring the necessary care in poultry farming. Dust particles settle on the skin, where they have an irritant effect or are inhaled into the respiratory tract bodies of birds. These particles are transferred microorganisms causing a variety of diseases. It is therefore desirable to eliminate the amount of such particles to the maximum extent possible.
