Aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium, also known as a gas dispersion system. The dispersed phase is a solid or liquid small particle with a size of 0.001 to 100 μm, and the dispersion medium is a gas. Liquid aerosols are often referred to as mists, and solid aerosols are often referred to as mist smoke.
Clouds, fog, dust in the sky, smoke from unburned fuel in boilers and various engines used in industry and transportation, solid dust from mining, quarry abrasives and grain processing, Artificial masking smoke screens and poisonous smoke are specific examples of aerosols.
The elimination of aerosols mainly depends on atmospheric precipitation, collisions between small particles, condensation, aggregation and sedimentation.
