Abstract
Acidic aerosols were measured simultaneously at two sites in Germany: Düsseldorf in a dense populated area and Grafschaft (Sauerland) in a remote mountain range. The concentrations of SO2, HNO2 and NH3 are much higher in Düsseldorf compared to Grafschaft. The concentrations of SO sub 4 high 2 minus, NO sub high minus, Cl high minus and NH sub 4 high plus in the particles are in most cases higher in Düsseldorf. Gaseous HNO3 and the H high plus sub minus content of the particulate matter are much higher in Grafschaft. The results indicate a higher oxidation potential in the remote mountain range compared to the urban area. Correlations between the components and the influence of meteorological parameters are discussed.
