five granulometric fractions, ie 1000–500 μm, 500–250 μm, 250–100 μm, 100–71 μm and<
71 μm, for street dust collected at two locations in Warsaw. Combination of grain-size
determination, magnetometry, electron microscope observation, mineral composition and
chemical analyses was applied as an effective and multidisciplinary approach for the
complete characterization of individual fractions of street dust. The magnetic properties of …
