We present some results of H2SO4 and ammonium sulfate concentration measurements with an ECN thermodenuder system. Data on aerosol composition obtained with standard filter-sampling based analysis are presented. It is shown, that SO-,4 is present in the particulate matter not only in the form of secondary aerosol of ammonium sulfate, but also in the form of associates with the lithophyll cations of calcium and magnesium.
