Chemicool was created by David D. Hsu. of the Massachusetts Institute of Technology in 1996. Chemicool went online in 1996 and since then has been trying to help out anyone involved in chemistry. This dictionary can be searched or browsed alphabetically.

Glossary of chemical terms and definitions of terminology related to the science of chemistry.

This dictionary contains definitions for most chemistry, environmental and other technical terms used on this site as well as many other chemistry and environmental terms.

Each element has its own page that includes a description, history of the discovery and naming of the element, a list of the names of the element in 70 languages, at least one illustration of the element, and links to other Web sites with more information.

This glossary, a revision of the IUPAC “Glossary for Chemists of Terms Used in Toxicology” [Pure Appl. Chem. 65, 2003 (1993)] incorporating new and redefined terms from the “Glossary of Terms Used in Toxicokinetics” [Pure Appl. Chem. 76, 1033 (2004)], contains definitions and explanatory notes, if needed, for terms frequently used in the multidisciplinary field of toxicology. The glossary is compiled primarily for those scientists and others who now find themselves working in toxicology or requiring a knowledge of the subject, especially for hazard and risk assessment. Many medical terms are included because of their frequent occurrence in the toxicological literature. There are three annexes, one containing a list of abbreviations and acronyms used in toxicology, one containing a list of abbreviations
and acronyms used by international bodies and by legislation relevant to toxicology and chemical safety, and one describing the classification of carcinogenicity according to the weight of evidence available.

Included here are common terms related to safety data sheets, GHS and other regulatory documents.
