    NMR Aerosolomics offers a different analysis approach of water-soluble organic compounds (WSOCs) from complex aerosol mixtures, inspired by the profiling of substances in metabolomics. To this end, an extensive library of compounds commonly found in atmospheric aerosols was created. The method was evaluated on a set of 21 samples of aerosol particulate matter (PM2.5 and PM10) collected in summer 2008 and winter 2009 at a Prague suburban site. Approximately 60 compounds were identified in each sample. Three compounds were identified for the first time in atmospheric aerosols and the presence of four other theoretically predicted species was confirmed. In total, the number of identified compounds reached 79. The concentration values of the identified compounds were then used for statistical analysis. A clear differentiation between summer and winter samples was obtained, while separation by particle size was indicated only in the group of summer samples. Univariate statistical analysis revealed which compounds were responsible for the group separation, and possible sources for these compounds were suggested.
