Short summary
The magnetic fraction of the aerosols in Kraków was collected and analysed using scanning and transmission electron microscopy with energy-dispersive spectrometry, X-ray diffraction, Mössbauer spectrometry, and magnetometry. It contains metallic Fe or Fe-rich alloy and Fe oxides. The occurrence of nanometre-scale Fe3O4 particles (predominantly of anthropogenic origin) is shown. Our results can help to determine the sources and transport of pollutants, potential harmful effects, etc.
