Air Pollution, Third Edition, Volume IV: Engineering Control of Air Pollution focuses on the sampling, measurement, analysis, and monitoring of air pollution. This book discusses the various gas and air cleaning devices used to eliminate or reduce emissions of air polluting substances. Organized into three parts encompassing 21 chapters, this edition starts with an overview of the methods of air pollution control that are designed to minimize the production or emission of contaminants. This book then discusses the techniques of rational air use management, which is based on the principle that air quality standards have been set at levels that protect the population from harm with an acceptable margin of safety. This text explores as well the waste-disposal process of incineration in which combustible wastes are burned completely under controlled conditions. Other chapters discuss the production of nonferrous metals, which has been very significant in the development of the science of air pollution control. Engineers, physicist, chemists, meteorologists, agronomists, toxicologists, sociologists, physicians, and lawyers will find this book extremely useful.
