The investigations performed by applying electron microscopy (SEM-EDS technique) unequivocally confirmed the results made by using XRF, the X-ray diffraction and the results from the determination of chemical composition of particles PM-10 with the application of the ICP-AES and ICP-MS. From the results performed with all of the applied techniques it can be concluded that the presence of specified mineral phases that have typically anthropogenic origin are registered as well as the mineral phases that have lithogenic origin or the origin of the present geological structure. Therefore, it can be concluded that the urban dust with a sizes below 10 μm (PM-10) in the Tikveš area originated from lithogenic and anthropogenic processes. It can be concluded that the phase composition of the particles PM10 from Tikveš area consisting of mineral phases which have anthropogenic origin confirmed by the high content of Fe, Ni, Cu, Zn, Ag, Cr (present in higher content in the ore processed in the ferronickel smelter), and by the presence of the minerals like: chlorite, amphibole, pyroxene, magnetite, chromites, Ag-minerals (chlorargyrite), metallic forms of Mn-Cr, Cu-Zn (also present in the ore processed in the smelter plant). The lithogeneic origin of the part of PM10 is confirmed by the presence of minerals quartz, calcite or plagioclase clay minerals.
