Dust composition

Dust is composed of coarse sand and a large number of fine particles (dust). The particle size of dust is mostly concentrated in 0. 1 ~ 0.5 mm, while the particle size of dust is 0.0039 ~ 0.25 mm, among which fine particles with particle size ≤ 10μm can enter the deep respiratory tract with breathing, causing lung injury effect.
