Basic Aerosol Science

Abstract

Aerosol contaminants can be injurious to health, therefore it is essential to understand the behavior and properties of the aerosol. Health effects caused by aerosols depends on particle size and size distribution as well as on the composition of the particles. Other aerosol behavior including light scattering and coagulation can also vary markedly with particle size. This chapter focuses on various properties of the aerosol particle which influence the behavior, such as Stokes law, Reynolds number, Cunningham correction factor, particle motion, electrical properties, and optical properties. Keywords: particle size; particle bounce; brownian motion; homogeneous nucleation
