| Americas (The landmasses and islands of North America, South America, Mexico, and Central America included in the Western Hemisphere) | Americi | |
| Americas | America | |
| Ames test (A bioassay developed by Bruce N. Ames in 1974, performed on bacteria to assess the capability of environmental chemicals to cause mutations) | test Ames | |
| amine (One of a class of organic compounds which can be considered to be derived from ammonia by replacement of one or more hydrogens by organic radicals) | amină | |
| amino acid (Organic compounds containing a carboxyl group (-COOH) and an amino group (-NH2). About 30 amino acids are known. They are fundamental constituents of living matter because protein molecules are made up of many amino acid molecules combined together. Amino acids are synthesized by green plants and some bacteria, but some (arginine, histidine, lysine. threonine, methionine, isoleucine, leucine, valine, phenylalanine, tryptophane) cannot be synthesized by animals and therefore are essential constituents of their diet. Proteins from specific plants may lack certain amino acids, so a vegetarian diet must include a wide range of plant products) | aminoacid | |
| ammonia (A colorless gaseous alkaline compound that is very soluble in water, has a characteristic pungent odour, is lighter than air, and is formed as a result of the decomposition of most nitrogenous organic material, NH3) | amoniac | |
| ammonification (Addition of ammonia or ammonia compounds, especially to the soil) | amonificare | |
| ammonium (The radical NH4+, NH4) | amoniu | |
| ammonium phosphate | fosfat de amoniu | |
| amphibian (A class of vertebrate animals characterized by a moist, glandular skin, gills at some stage of development, and no amnion during the embryonic stage) | batracian | |
| amusement park (An open-air entertainment area consisting of stalls, side shows etc.) | parc de distracţii | |
| anaerobic condition (A mode of life carried on in the absence of molecular oxygen) | condiţie anaerobă | |
| anaerobic digestion | digestie anaerobă | |
| anaerobic fermentation | digestie anaerobă | |
| anaerobic process (A process from which air or oxygen not in chemical combination is excluded) | proces anaerob | |
| anaerobic treatment (Breakdown of organic material without the presence of oxygen, a treatment which permanently removes the unpleasant odour of many organic wastes so that they can be used on agricultural land) | tratare anaerobă | |
| analysis (Examination or determination) | analiză | |
| analysis programme (No definition needed) | program de analiză | |
| analytical chemistry (The branch of chemistry dealing with techniques which yield any type of information about chemical systems) | chimie analitică | |
