Particle Size Analysis in Industrial Hygiene discusses technical information on particle properties, kinetic behavior, sampling instruments, and interpretation. This book is composed of seven chapters and is prepared by the American Industrial Hygiene Association for the Division of Technical Information, United States Atomic Energy Commission. This monograph is a part of the continuing effort of both organizations to extend the field of technical knowledge and safeguard the health and well-being of persons exposed to toxic or deleterious material. After briefly discussing the fundamental physics and chemistry of aerosol systems, the book goes on describing the analytical methods and instruments for particle size analysis. Such methods include direct and indirect sampling methods as well as automatic counting and sizing instruments. Specific methods considered include sieve analysis, optical and electron microscopy, and scanning electron microscopy. A chapter on particle size interpretation and representation with the use of applied mathematical statistics concepts is also provided. This book also covers a general discussion on typical applications of particle size analysis to industrial hygiene, radiation protection, air pollution control, industrial toxicology, and related areas. This book is an invaluable source for industrial hygienists and to those working in the many disciplines dealing with particle behavior.
