Dust emission from crushing of hard rock aggregates
Crushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source. The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher. The mass concentration of fine particles (PM 2.5 and PM 1) ranged between ten μg/m 3 and few hundreds of μg/m 3 ...Web
