Zhodnocení kvality ovzduší v zájmovém území na základě vybraných ukazatelů
Sklenář, Tomáš
This bachelor thesis deals with the evaluation and development of air quality in the city of Znojmo based on selected indicators. The theoretical part first deals with the key legislative, administrative and economic instruments of air quality protection in the Czech Republic. In addition, the selected site will be described and the key sources of pollution will be identified. The most significant pollutants such as SO2, which due to relatively low concentrations stopped measuring at the site in 2012 and whose daily concentrations rarely exceeded 15 μg.m- 3, which is well below the immission limit. Another substance is carbon dioxide (CO), which also did not exceed the limit value set by the law and its concentration was almost not above 500μg.m-3. Nitrogen oxides (NOx), nitrogen dioxide (NO2) and nitric oxide (NO) were also not out of the legal limits set by the law in the reporting period. However, it was found out that dust particles PM10, as opposed to dust particles PM2.5, exceeded the immission limit given by law not only in terms of permitted concentrations but also in the maximum number of exceedances. These pollutants emitted into the atmosphere are then evaluated, including impacts they have or may have on the environment. As a procedure for the elaboration of the theoretical part, the study of professional literature, professional journals and professional articles, both foreign and domestic, will be used. The practical part is in the form of compilation of the database of data on pollutants from data obtained from monitoring stations of the Czech Hydrometeorological Institute, which are located in a locality, from the period 2009-2016. At the end of the bachelor thesis there is a statistical and graphical evaluation of the results obtained from tabular surveys published by the Czech Hydrometeorological Institute.
