Bridging the gap between toxicology and chemistry, this book covers both at a level understandable by a wide spectrum of readers. The third edition of a best-selling resource, it has been thoroughly updated and expanded to reflect recent advances in areas such as the toxic effects and analysis of xenobiotics. A new chapter on the genetic aspects of toxicology discusses how chemical damage to DNA can cause mutations, cancer, and other adverse effects on specific body systems. The author explores the role of genetics in determining individual susceptibilities to various toxicanants. With review questions and references at the end of each chapter, this book is ideal as both a textbook and a reference.
