Toxicology holds a place as important as pharmacology in medical education. This book is primarily aimed at undergraduate and graduate students, but it has also been prepared taking into account the needs and expectations of our colleagues in academia who wish to acquire a higher level of knowledge in toxicology. It is a resource that can be used by those undergoing pre- and post-graduate education, as well as physicians, pharmacists, and researchers interested in the science of toxicology. The book has been prepared as a reference work that covers toxicokinetics, toxicodynamics, organ toxicities, environmental toxins, clinical toxicology, and specific antidotes in detail. It is hoped that this book will meet the need for reference books in the field of toxicology in our country, both at the undergraduate and graduate levels.
