| Terms for subject Environment (5949 entries) |
| biltzar | congress (A formal meeting, often consisting of representatives of various organizations, that is assembled to promote, discuss or make arrangements regarding a particular subject or some matter of common interest) | |
| bioakumulazio | 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) | |
| biodegradagarritasun | biodegradability (The extent to which a substance can be decomposed - or rotted - by bacteria and fungi. Implies that residues from degradation are nontoxic. One of the most misleading claims in business, because shoppers often assume a biodegradable product to be harmless. Some harmful compounds take much longer to degrade than others and the product can harm the environment while it is rotting. Biodegradation may also be incomplete, sometimes leaving residues in the environment which are more harmful than the original substance. Accumulation in the environment of nonbiodegradable (or poorly biodegradable) substances, such as some biocides, can cause serious problems) | |
| biodegradazio | biodegradation (Breaking down of a substance by microorganisms) | |
| biodibertsitate | biodiversity (1. Genetic diversity: the variation between individuals and between populations within a species; species diversity: the different types of plants, animals and other life forms within a region; community or ecosystem diversity: the variety of habitats found within an area - grassland, marsh, and woodland for instance. 2. An umbrella term to describe collectively the variety and variability of nature. It encompasses three basic levels of organisation in living systems: the genetic, species, and ecosystem levels. Plant and animal species are the most commonly recognized units of biological diversity, thus public concern has been mainly devoted to conserving species diversity) | |
| bioerregai | biofuel (A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is beginning to be exploited to supply the ever-increasing energy demand around the world. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol) | |
| bioetika | bioethics (The study of ethical problems arising from biological research and its applications in such fields as organ transplantation, genetic engineering, or artificial insemination) | |
| biofisika | biophysics (The hybrid science involving the application of physical principles and methods to study and explain the structures of living organisms and the mechanics of life processes) | |
| biogas | biogas (Gas, rich in methane, which is produced by the fermentation of animal dung, human sewage or crop residues in an air-tight container. It is used as a fuel, to heat stoves, lamps, run small machines and to generate electricity. The residues of biogas production are used as a low-grade organic fertilizer. Biogas fuels do not usually cause any pollution to the atmosphere, and because they come from renewable energy resources they have great potential for future use) | |
| biogeografia | biogeography (The science concerned with the geographical distribution of animal and plant life) | |
| biogeokimika | biogeochemistry | |
| bioiragazketa | biofiltration (The distribution of settled sewage on a bed of inert granular material through which it is allowed to percolate. In doing so, the effluent is aerated thus allowing aerobic bacteria and fungi to reduce its biochemical oxygen demand) | |
| bioiragazki | trickling filter (A system of secondary sewage treatment which is similar to self-purification action of streams; it is more accurately a biological oxidizing bed; the effluent is placed on the stones in the bed and microorganisms present consume the solids as a food supply) | |
| biokimika | biochemistry (The study of chemical substances occurring in living organisms and the reactions and methods for identifying these substances) | |
| bioklimatologia | bioclimatology (The study of climate in relation to fauna and flora) | |
| biokontzentrazio-faktore | bioconcentration factor (The quotient of the concentration of a chemical in aquatic organisms at a specific time or during a discrete time period of exposure, divided by the concentration in the surrounding water at the same time or during the same period) | |
| biologia | biology (A division of the natural sciences concerned with the study of life and living organisms) | |
| biologia molekular | molecular biology (The study of the chemical structures and processes of biological phenomena at the molecular level; the discipline is particularly concerned with the study of proteins, nucleic acids, and enzymes, the macromolecules essential to life processes. It seeks to understand the molecular basis of genetic processes. Techniques used include X-ray diffraction and electron microscopy) | |
| biolumineszentzia | bioluminescence (The production of light of various colors by living organisms (e.g. some bacteria and fungi, glow-worms and many marine animals). Luminescence is produced by a biochemical reaction, which is catalyzed by an enzyme. In some animals the light is used as a mating signal; in others it may be a protective device. In deep-sea forms luminous organs may serve as lanterns) | |
| biomasa | biomass (Biomass refers strictly speaking to the total weight of all the living things in an ecosystem. However, it has come to refer to the amount of plant and crop material that could be produced in an ecosystem for making biofuels and other raw materials used in industry, for example) |
