Translated into six languages, Lu's Basic Toxicology: Fundamentals, Target Organs, and Risk Assessment is a benchmark text that brings clarity and insight into a rapidly evolving subject. Topics covered include the general principles of toxicology, inhalation toxicology, toxic substances, and the testing procedures for conventional and non-target organ toxicities. Noted for its concise yet broad coverage of the subject, this fourth edition includes new chapters on over-the counter preparations, lactation and occupational toxicology. In addition, it covers the action of chemicals that cause cancer, mutations, congenital malformations and organ or system specific effects.
