Conditions Affecting Wind-Induced PM10 Resuspension as a Persistent Source of Pollution for the Future City Environment

Air pollution by particulate matter (PM) in cities is an ongoing problem with increasing severity. The biggest PM contributors are traffic and domestic fire burning. With the shift towards electromobility use of low-emission fuels, attention should be shifted to less mentioned sources pollution. Such include wind-induced resuspension. This study focuses on determining threshold wind speed causing resuspension (TWSR) aerodynamic diameter smaller than 10 µm. A methodology introduced that examines how data could treated identify its characteristics (for locations where only PM10 available). most significant monitored parameters air humidity, direction, time day, surface type. characteristic speeds identified four for different times day. It was proven at intense human activity, particles lifted more easily. mean studied urban environment as 1.58 m/s a height 2 m above surface. were also compared experimental studies results proved correspondence between results.
