Resuspension of Road Traffic Related Particulate Matter to the Environment
An important source of suspended particles PM in urban air is the resuspension of road dust. The aim of the described study was to collect road dust at sampling points and to determine its size distribution by a classical screening test. Grains of road dust passed through a 0.125 mm sieve (sub-sieve fraction) are subjected to X-ray fluorescence spectroscopy to determine the chemical composition. At the measuring station, measurements of particulate matter PM10, PM2.5 and PM1 were performed by the gravimetric method (sampling of particulate matter on filters). In addition, measurements were performed with SMPS and APS particle size spectrometers, which monitored the distribution of aerosol in the range of 12 nm to 20 µm. The amount of selected chemical elements in the particulate samples obtained by the gravimetric method was determined by inductively coupled plasma mass spectrometry (ICP-MS). Based on chemical analyzes of collected road dust and particulate matter collected from the air, the concept of the possible contribution of road dust resuspension to the concentration of particulate matter in the air was determined.
