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
