Abstract

"Sub-micron particulate matter emissions from various combustion sources such as power plants and diesel engines have serious negative impacts on health and environment as they can penetrate through the human respiratory system and accelerate global climate forcing. Accurate characterizations of such PM emissions based on independent diagnostic techniques are essential to monitor, regulate and model atmospheric pollution levels so that a broad scientific database can be reached to guide improvements in environmental policies. Of current interests are the relevant sizes of combustion-generated particulates that are typically fractal aggregates of small spherical primary particles. Separate measurement of spherule and aggregate sizes, in addition to mass, is crucial as they determine the transport, toxic, optical, chemical and deposition properties of particulates. In this study, three different experimental methods were critically evaluated and compared for their abilities to characterize size of soot particulates from a well-controlled laminar burner"--Abstract, page iii.
