ITER is a free Internet database of human health risk values and cancer classifications for over 680 chemicals of environmental concern from multiple organizations worldwide. ITER is the only database that presents risk data in a tabular format for easy comparison, along with a synopsis explaining differences in data and a link to each organization for more information.

The Chemical Reactivity Worksheet (CRW) is a free software program you can use to find out about the chemical reactivity of thousands of common hazardous chemicals. (Reactivity is the tendency of substances to undergo chemical change, which can result in hazards—such as heat generation or toxic gas byproducts.) The CRW predicts possible hazards from mixing chemicals and is designed to be used by emergency responders and planners, as well as the chemical industry, to help prevent dangerous chemical incidents. The chemical datasheets in the CRW database contain information about the intrinsic hazards of each chemical and about whether a chemical reacts with air, water, or other materials. It also includes case histories on specific chemical incidents, with references. You can also create your own custom chemical datasheets, as you might do, for instance, if your facility produces a proprietary chemical that is not in the CRW database.

Chélation Chélation Un article de Wikipédia, l'encyclopédie libre. Complexe chélate de l'EDTA avec un cation métallique Le « chélate » se distingue du simple « complexe » par le fait que le cation métallique est fixé au chélateur par au moins deux liaisons de coordination définissant un cycle avec le métal, à la manière d'une pince, d'où le nom. Le nombre de liaisons métal-ligand qu'il est possible de former définit la « denticité » : on parle de coordinats bidentes, tridentes, tétradentes, etc, ainsi que de ligands monodentates, bidentates, polydentates. L’atome central est lié aux atomes voisins par au moins deux liaisons en formant une structure annulaire, un cycle chélate. Les cycles chélates les plus stables sont les cycles chélates à 5 et à 6 chaînons.
