Fine Particles Applications
Fine dust is generated by industrial exhaust gases but in particular due to traffic. Environmental pollution is therefore caused particularly by exhaust gases of diesel-engined vehicles (diesel soot) but on the other hand also by abrasion of street, tyres and brakes and its resuspensions.

The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.
