xvi PREFACE • The approach is scientific, but applied, rather than theoretical. In this it differs from more general works in toxicology, which fail to emphasize the information pertinent to the industrial environment. • The book consistently stresses evaluation and control of toxic hazards. • Numerous illustrations and figures clarify and summarize key points. • Case histories and examples demonstrate the application of toxicological principles. • Chapters include annotated bibliographies to provide the reader with additional useful information. • A comprehensive glossary of toxicological terms is included. Phillip L. Williams Robert C. James Stephen M. Roberts
ACKNOWLEDGMENTS A text of this undertaking on the broad topic of toxicology would not be possible except for the contributions made by each of the authors in their field(s) of speciality. We especially appreciate the contributors patience during the many years it took to complete this revision. In addition, such an undertaking would not have been possible without the support provided by each of our employers— The University of Georgia, TERRA, Inc., and The University of Florida. We also owe a thank you to Valerie Rocchi for her administrative assistance throughout the effort and to Dr. Kelly McDonald for her editorial assistance. Phillip L. Williams Robert C. James Stephen M. Roberts xvii
