Magnetic fraction must be removed from road dust using magnetic separation the fly dust of coal during transportation must be suppressed, and covers must be used in coal yards the mass contents of TWP and CB in road dust should be removed by vacuum cleaning instead of water flushing. Finally, to reduce the exposure of the finest particles to road dust, three methods were suggested. Coal was only found in the steel complex. Created using macro photography of natural dust, these excellent video clips can be used as. The 2nd Dust and Scratches Pack contains 12 stylized and bold-looking overlay effects. The maximum concentrations of TWP and CB originating from the vehicle varied depending on the region and particle size range: TWP 2.066 wt% at 45-75 μm (industrial complex) and CB 5.559 wt% at 75-160 μm (steel complex). The dust particles are subtle, while the stray hair effect adds realism, ideal for creating a realistic period film.

The enrichment factors of Mn, Zn, and Ni were higher than two, indicating that they were related to industrial activities in steel complexes. As the particle size decreased, the mass content of Fe, Mn, and TWP increased. In the magnetic separation for <45 μm fraction, 34.4 wt% and 50.9 wt% was removed for steelmaking and steel-related industrial complexes, respectively.

The mass distribution of TWP, carbon black (CB), bituminous coal, and heavy metals (Fe, Zn, Mn, Pb, Ni, As, Cu, Cd, and Hg) in different size fractions of road dust was quantified by combining four different analytical techniques. Road dust samples were collected from three areas near steelmaking complexes. Herein, road dust collected from steel industrial complexes with high traffic of high-weight vehicles and the composition distribution of five size-fractioned particle sizes were analyzed. The mass content of metallic species in road dust may increase owing to the traffic of heavy vehicles and industrial activity consequently, metallic particles are also present in road dust. For example, after the macrophages swallow silica particles, they die and give off toxic substances. The amount of dust and the kinds of particles involved influence how serious the lung injury will be. Tire-wear particles (TWP) from vehicles serves as a non-exhaust emission source. Dust particles and dust-containing macrophages collect in the lung tissues, causing injury to the lungs.
