In the recent study, the summer and winter aerosol samples were analyzed using NMR aerosolomics ap-proach. The samples were collected in Prague-Suchdol during summer 2008 and winter 2009 in two different particle size fractions - PM2.5 and PM 10. Around 50 compounds were identified in each aerosol spectrum owing to the comprehensive library. The profile of 86 compounds identified in the samples altogether served as an input data for statistical analysis. Multivariate statistical analysis clearly discriminates the two groups studied. Furthermore, the most significant compounds varying between seasons were determined by the means of univariate statistical analysis. These compounds were subjected to further analysis of their possible sources.
