What is aerosol?
We will deal with aerosol and natural phenomenon of aerosol. Aerosols, small particles suspended in air with a lifetime of at least minutes, are either emitted as primary aerosols or formed by the conversion of sulfur dioxide, nitrogen oxides, ammonia and organic compounds in atmospheric chemical reactions to sulfates, nitrates and ammonium compounds, and non-volatile organics (secondary aerosol). The total mass of aerosols per unit of volume is called "Particulate Matter." PM-10 is the mass of aerosol particles with a diameter of 10 micrometers or smaller. PM-2.5 is the mass of aerosol particles with a diameter of 2.5 micrometers or smaller. We will deal with aerosol and natural phenomenon of aerosol. An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas. Examples of aerosols include haze, dust, particulate air pollutants and smoke. The liquid or solid particles have diameter mostly smaller than 1 μm or so; larger particles with a significant settling speed make the mixture a suspension, but the distinction is not clear-cut. In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container.
