The Dose Makes the Poison
John Wiley & Sons Inc (Verlag)
978-0-470-38112-0 (ISBN)
This new edition of a widely-read and highly-acclaimed book broadens the scope of its predecessors from a heavy focus on industrial chemicals as toxicants to include drugs, food additives, cosmetics and other types of compounds that people are exposed to daily. Also new to the 3rd edition are newer issues-of-the-day such as nanoparticulate toxicants, second hand smoke, food contamination, lead in toys, and others. As such, the book provides the basics of toxicology in easy-to-understand language as well as a fuller understanding of the daily insults to which our bodies are subjected.
Patricia Frank is President of Patricia Frank & Associates, Inc., a consulting firm founded in 1993 that assists companies in the development and registration of human and veterinary pharmaceutical agents. She is a past president of both the American College of Toxicology and the Roundtable of Toxicology Consultants. M. Alice Ottoboni lectures, writes, and consults in the field of toxicology. As Staff Toxicologist with the California State Department of Public Health for over twenty years, she originated, designed, and performed numerous toxicological studies of environmental factors of importance to public health. She is the author of the previous editions of The Dose Makes the Poison.
