Long-term analysis of major ambient air pollutants in the Czech Republic
Šmejkalová, Marie ; Hůnová, Iva (advisor) ; Braniš, Martin (referee)
The thesis evaluates the long-term development of concentration of major air pollutants (sulphur dioxide, nitrogen oxides and particulate matter) at 17 air pollution monitoring stations. Chosen stations include automated monitoring as well as manual measuring stations and the locales cover the range from nature background stations (CR) to industrial and transport sites (in polluted areas of CR). The development of air pollution on the representative set of measurements is supplemented by the progress of pollution inventory of SO2, NOX and particulate matter from man-caused sources, and present state and development of pollution of precipitation and wet deposition in recent years. The pollution data was processed using monthly average concentrations by basic statistical methods of comparing multiple samples and time-series data analysis. Contemporary progress in recent years was considered in evaluation of air pollution, plus progress in the 90s characterised by pronounced changes and preceding period. The surveilled period is concerned mainly with problematics of SO2, from the trend of growing concentrations, across slight decline, followed by rapid decline in the course of the 90s till the present, when the SO2 moves gradually out of focus. The magnitude of decline depends on the locale pollution,...
