Airborne aerosol is a suspension of solid particulate matter and/or liquid particles in air, which are often observed as dust, haze and smoke. They present an overall number concentration usually varying between a few hundred per cubic centimeter of air in the remote areas of the planet and more than 104 cm-3 in the most polluted urban areas, with sizes ranging mainly between 0.01 and no more than 100 µm, and therefore varying by more than four orders of magnitude (Heintzenberg, 1994). Aerosol particles are present in the atmosphere as a result of primary emissions or are formed through secondary processes involving both natural and anthropogenic gaseous species.
