CHEMICAL COMPOSITION AND SIZE DISTRIBUTION OF FINE AEROSOL PARTICLES ON THE EAST COAST OF THE BALTIC SEA
The size distribution and chemical composition of ambient aerosol particles (PM1) were measured using an Aerodyne aerosol mass spectrometer (AMS) at the Preila air pollution research station on 3–15 September, 2006. The major observed components of aerosol particles were sulfate and organic matter w...

The size distribution and chemical composition of ambient aerosol particles (PM1) were measured using an Aerodyne aerosol mass spectrometer (AMS) at the Preila air pollution research station on 3–15 September, 2006.

Large contribution of organic matter was established in all air masses, however it reached 60 % of the total aerosol particle mass in the North Atlantic marine air masses. The analysis of size distribution spectra enabled us to explain the origin of aerosol chemical components.
