|---|---|---|---|
| acute toxicity: Wikipedia: acute toxicity |
Toxicity of a one-time dose of a chemical or a short exposure time. | chronic toxicity | |
| adaptation: Wikipedia: adaptation |
The ability of organisms to adapt to different environmental conditions. Metabolic adaptation can boost an otherwise low ability to degrade organic substances. | ||

| atmospheric half life: Wikipedia: atmospheric half life |
The time it takes for the concentration of a substance to be halved by reactions with oxidants in the atmosphere. (Standardized here for a OH radical concentration of 1.5 * 10^6 radicals/cm3 and a reaction time of 12h/day). | ||
| atom economy: Wikipedia: atom economy |
Atom economy is based on the stoichiometric equation and equals the theoretically achievable yield for complete reaction of the educt without the formation of by-products. It is dependent on the reaction type. (B. M. Trost, Angew. Chem. Int. Ed. Engl. 1995, 34, 259-281) | , yield | |
| autoignition temperature: Wikipedia: autoignition temperature |
The temperature at which substance vapors may spontaneously ignite. | flash point | |
| auxiliary materials: | Collective term for chemical substances that are used in a chemical reaction besides educts and reagents. |
