Since the publication of the first edition of this text, toxicology has become a more mature science and the number of courses has greatly increased. The need for an introductory text is, therefore, growing. This second edition caters for this need in a clear and easy-to-read style, featuring updated information and new examples, an extensively revised bibliography, essay type questions at the end of each chapter, illustrations and a glossary.; The fundamental principles of absorption, distribution, metabolism and excretion are described in the introductory chapters, as are the types of exposure and response. In subsequent chapters these are clarified with the use of carefully chosen examples. Among the topics considered are the potential adverse effects of drugs, pesticides, food additives and industrial chemicals.
