The Rating of the Relation between the Composition of Solid Matter in the Atmosphere and Their Sources in Selected Areas of Prague

From eght chemical composition of aerosols PM10 and PM2,5 from two areas in Prague on the end of winter and in sommer in analogy with statistical analyses of other authors it was concluded which are possible sources of aerosols in the areas of measurement. For chemical analysis AAS, iont chromatography and X-ray fluorescence methods were used..Soil dust and fine silicates there are a very probable source of aerosols . In connection with realisation of a few measurements the existence of other sources (heating, traffic, cment kiln, industry, ammonium sulphate, nitrate iont) is discussed
