| Description
| - The aim of this study is the assessment of 1996-2005 PM data from the Czech air quality monitoring network. Gradual decline in emissions of PM after 1989 in the Czech Republic was caused by general decrease of industrial production and reduction in electricity generation in conventional thermal power stations. In the beginning of new millennium the decreasing trend was interrupted and the emissions slightly increased. Decreasing trend of PM10 concentration was registered in the period 1996-1999 at all types of stations (traffic, urban, suburban, rural and regional), but this trend was stopped in the beginning of this century and the concentrations slightly increased and the differences between types of stations became smaller. The most serious situation is in the Moravian-Silesian region. This is caused by the fact that in this area, in addition to transport and local sources of PM significant contribution is made by further emission sources (metallurgy, fuel processing). Regional transfer from Poland (heavily industrialized Katowice region) is also very significant. The PM10 concentrations in winter are higher than in the summer, the most significant annual variation was found at traffic stations. In 2005 measurements of PM2,5 began at 25 localities. The results show significant contribution of PM2,5 fractions to air pollution situation in the Czech Republic. The proposed annual air pollution limit would be exceeded in more than 10 sites, mainly in the Moravian-Silesian region. The ratio between PM2,5 and PM10 shows certain seasonal course that is connected with the seasonal character of several emission sources. (en)
