Interest and information in the field of Medical Toxicology has grown rapidly, but medical literature lacks a concise, authoritative reference work on Medical Toxicology that focuses on the four subjects of Natural Substances, Chemical and Physical Toxins, Drugs of Abuse, Pharmaceutical Overdose. The book series will be an in-depth, sub-specialty resource on Medical Toxicology that does not compete directly with a general medical toxicology book. This approach is particularly relevant in the field of Medical Toxicology where there are many allied fields (e.g., industrial hygiene, governmental agencies, legal profession, occupational medicine, pharmacy, environmental organizations, pathology). These allied fields often do not use the majority of information in a general medical toxicology book.  The style of the book allows the easy application of the contents to searchable databases and other electronic products.
