Physical Properties of Atmospheric Particulates

  • Roger J. Cheng


Microscopic investigations of atmospheric particulates reveal a complex variation with respect to size and shape. Emission from combustion processes contributes more than 70% of the fine particle burden in the atmosphere. Flyash from coal-fired boilers have a relatively smooth surface in contrast to flyash from oil-fired boilers which have a rough, honeycomb-like surface. Particles from automobile exhaust and smoke are extremely small, spherical, and fairly uniform in size. In addition they always exhibit a chain-like aggregation.
