"Harmful of toxic substances enter the body through the air we breathe, through food or water ingested, or through the skin. This book by two prominent epidemiologists explores the relationship between air pollution and health. The book is well documented and well illustrated and provides a wealth of useful information including epidemiologic results and standards or requirements that influence air quality—both indoor and out. the 17 edited contributions are divided into discussions of (1) sources, (2) health effects, and (3) control and legal aspects. Each chapter is a detailed but readable review, of excellent quality and reliability. Particularly strong are the chapters on indoor air pollution, nitrogen dioxide, wood smoke, formaldehyde, and radon. Worldwide in coverage, this volume successfully provides a review for policy makers, engineers, lawyers, and health professionals, and for students in these disciplines, undergraduate and graduate."
