| beneficiu conex | co-benefit | |
| beneficiu ecologic | environmental benefit | |
| benthos | benthos (Those organisms attached to, living on, in or near the sea bed, river bed or lake floor) | |
| benzen | benzene (A colorless, liquid, flammable, aromatic hydrocarbon used to manufacture styrene and phenol. Also known as benzol, C6H6) | |
| benzină | petrol (A fuel for internal combustion engines consisting essentially of volatile flammable liquid hydrocarbons; derived from crude petroleum by processes such as distillation reforming, polymerization, catalytic cracking, and alkilation) | |
| benzopiren | benzopyrene (A five-ring aromatic hydrocarbon found in coal tar, in cigarette smoke, and as a product of incomplete combustion) | |
| beriliu | beryllium (A corrosion-resistant, toxic silvery-white metallic element that occurs chiefly in beryl and is used mainly in x-ray windows and in the manufacture of alloys) | |
| beton | concrete (A mixture of aggregate, water, and a binder, usually Portland cement; it hardens to stonelike condition when dry) | |
| bibliografie | bibliography (A complete or selective listing of documents by a given subject, author or publisher, often including the description and identification of the editions, dates of issue, titles, authorship, publishers or other written materials) | |
| bibliotecă | library (Place where books and other literary materials are kept) | |
| bicicletă | bicycle (A vehicle with two wheels in tandem, pedals connected to the rear wheel by a chain, handlebars for steering, and a saddlelike seat) | |
| bifenil halogenat | halogenated biphenyl (Halogen derivatives of biphenyl) | |
| bifenil polibromat | polybrominated biphenyl (A chemical substance the composition of which, without regard to impurities, consists of brominated biphenyl molecules) | |
| bifenil policlorurat | polychlorinated biphenyl (PCBs are a family of chemical compounds which do not exist in nature but which are man-made. Commercial mixtures are clear, pale yellow liquids, manufactured by the replacement of hydrogen atoms on the biphenyl molecule by chlorine. Because of their physical properties, PCBs are commonly found in electrical equipment which requires dielectric fluid such as power transformers and capacitors, as well as in hydraulic machinery, vacuum pumps, compressors and heat-exchanger fluids. Other uses include: lubricants, fluorescent light ballasts, paints, glues, waxes, carbonless copy paper, inks including newspapers, dust-control agents for dirt roads, solvents for spreading insecticides, cutting oils. PCBs are stable compounds and although they are no longer manufactured they are extremely persistent and remain in huge quantities in the atmosphere and in landfill sites. They are not water-soluble and float on the surface of water where they are eaten by aquatic animals and so enterthe food chain. PCBs are fat-soluble, and are therefore easy to take into the system, but difficult to excrete) | |
| bifenil policlorurat | polychlorinated biphenyl | |
| bilanț de mediu | environmental audit | |
| bioacumulare | bioaccumulation (1. The accumulation of pollutants in living organisms by direct adsorption or through food chains. 2. Accumulation by an organism of materials that are not an essential component or nutrient of that organism. Usually it refers to the accumulation of metals, but it can apply to bioaccumulation of persistent synthetic substances such as organochlorine compounds. Many organisms, such as plants, fungi and bacteria, will accumulate metals when grown in solutions containing them. The process can be employed usefully as a purification process to remove toxic heavy metals from waste water and contaminated land) | |
