Aerosol Dynamics

Abstract

Airborne particulate matter (PM) contains different chemical components, its size ranging from few nanometers to several hundred micrometers (Hinds, 1999). It is apparent that particulate matter is not a single pollutant, and its mass includes a mixture of numerous pollutants distributed differently at different sizes. Particle size is an essential parameter that determines the chemical composition, optical properties, deposition of particles, and their inhalation in the human respiratory tract (Hinds, 1999; Friedlander, 2000; Seinfeld and Pandis, 2006; Lazaridis, 2011). Particle size is specified by the particle diameter, , which is most commonly expressed in micrometers. Particles represent a very small fraction, less than 0.0001%, of the total aerosol mass or volume (Drossinos and Housiadas, 2005). The gas phase influences mainly the particle flow through hydrodynamic forces.JRC.F.6-Energy systems evaluatio
