Continuing a long tradition, Lus Basic Toxicology, Seventh Edition, combines relatively comprehensive coverage of toxic substances in food, air, and water with brevity, thereby continuing to serve as an updated introductory text for toxicology students and for those involved in allied sciences that require a background in toxicology. The new edition, which now becomes an edited work with contributions from experts around the globe, features four new chapters and a number of existing chapters that have been updated and expanded, notably those on mechanisms of toxic effects, conventional toxicity studies, the cardiovascular system, and risk assessment and regulatory toxicology. The book consists of four parts (Part I“Part IV) that provide guidance on principles of toxicology and testing procedures for toxicities as well as a concise, yet detailed, mechanism of both target organ and nontarget organ toxicities. The book is rounded off with a final section (Part IV) on the toxic effects of chemicals and risk assessment, giving toxicologists, both students and practicing professionals, the necessary tools to enhance their practice. This edition includes new chapters on Clinical Toxicology, Systems Toxicology, Chemicals and Children, and Toxicology of Reproductive Systems, providing the essentials of these topics in the same style as the other chapters in the book. With separate subject and chemical indexes, this is a useful, quick shelf reference for everyone working in toxicology today.
