Airborne particulate matter can be a complex mixture of organic and inorganic substances which might be divided into two groups: coarse and fine particles. The fine particles include formed aerosols (gas that looked to particles), combustion particles, and metal vapors. The large particles are items like dust in the road or a factory.
