Particulate matter (PM) air pollution is a matter of concern in most cities. Most of the PM is exhaust related, with dominant contributor, traffic. In the near future, we will see a shift toward electromobility and low emission heat sources. Non-exhaust sources of PM could be dominant. Resuspension of previously deposited PM is likely to increase its contribution. Resuspension process can be induced by wind or vehicles. It can be recognized from the long-term air quality data, creating a long-term characteristic of the process. In this paper the resuspension process of three PM fractions was recognized and characterized. Results show that wind-induced resuspension of PM1 fraction is a considerable source of pollution. The threshold wind speed causing resuspension (TWSR) is slightly lower for PM1 than for PM10-2.5. Considering the variability in the results, resuspension for PM1 and PM10-2.5 could happen simultaneously. Similarly, the intensity of resuspension is lower by 27% for PM1 than for PM10-2.5, still PM1 resuspension intensity cannot be neglected. Wind induced resuspension can contribute up to 8 mu g/m3 in each fraction. The analysis of the properties of resuspension showed, that except of resuspension intensity, PM10 has similar properties to each fraction. The values of TWSR are very much similar across all PM fractions. Still, resuspension properties seem to have large scatter and tends to be site specific.
