This glossary expands upon the Comprehensive Glossary of Terms Used in Toxicology. Like its predecessor, it addresses the need for harmonized toxicology terminology, and has undergone a full, comprehensive and rigorous review by IUPAC Committees. It serves as the reference glossary for students and researchers studying the chemical and molecular biological bases of toxicology, and for those involved in chemicals legislation, regulation and risk assessment. Toxicology uses terminology from many disciplines that have been revolutionized by recent developments in molecular biology and biochemistry, and this glossary provides a compilation of definitions of molecular entities that impact on toxicology. Extensive Notes are included to provide context for many of the proteins and important genes defined, with disambiguation where entities are referred to by different names in the literature. We hope that this will be helpful to students and professionals alike.

This glossary addresses the need for harmonised toxicology terminology. Fully comprehensive and rigorously reviewed by IUPAC Committees, it serves as the reference glossary for students and researchers in toxicology, and those involved in chemicals legislation, regulation and risk assessment. Toxicology uses terminology from chemistry, medicine, geology, botany, zoology, ecology, and veterinary medicine, as well as some legal terms. Toxicology has become crucial to global trade in chemicals as legislation is increasingly co-ordinated around the world and is based on the classification of toxicity. Consistent terminology is crucial for effective legislation and trade in the modern world.
