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...
