- Abstract
Identification of PM10 particles in the city of Olomouc (the Czech Republic) was aimed at determining the proportion of inorganic and organic compounds. Organic compounds in PM10 represent 30-36% of PM10, of which 21-25% is biogenic material (spores were identified). The rest of 10 to 15% of organic matter is represented by anthropogenic processes. Combustion processes (35.1 to 40.9% of PM10) and emissions from transport (20.0 to 22.9% of PM10) have the main share in the PM particles, minerals from resuspension - weathering processes and mechanical processes of construction activity account for around 9% of the particles and Fe - particles also constitute about 9%. The iron concentration in the aerosol is in accordance with the values measured in other European cities. Mineral phases in the inorganic aerosol were determined by X-ray diffraction. Both natural and anthropogenic crystalline phases were identified - quartz, clay minerals (kaolinite), feldspar, calcite, dolomite, iron oxides (magnetite), gypsum, boussingaultite, mascagnite and koktaite.
