| Terms for subject Environment (5582 entries) |
| biocida | biocide (A diverse group of poisonous substance including preservatives, insecticides, disinfectants and pesticides used for the control of organisms that are harmful to human or animal health or that cause damage to natural or manufactured products) | |
| bioclimatologia | bioclimatology (The study of climate in relation to fauna and flora) | |
| biodegradabilitat | 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) | |
| biodegradació | biodegradation (Breaking down of a substance by microorganisms) | |
| biodiversitat | 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) | |
| bioètica | bioethics (The study of ethical problems arising from biological research and its applications in such fields as organ transplantation, genetic engineering, or artificial insemination) | |
| biofiltratge | 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) | |
| biofiltre | 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) | |
| biofísica | 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) | |
| biogàs | 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) | |
| biogeoquímica | biogeochemistry | |
| biologia | biology (A division of the natural sciences concerned with the study of life and living organisms) | |
| biologia animal | animal biology (The scientific study of the natural processes of animals) | |
| biologia d'estuaris | estuarine biology (The scientific study or the characteristic life processes of living organisms found in a semi-enclosed coastal body of water which has a free connection with the open sea and within which sea water is measurably diluted with freshwater) | |
| biologia de l'aigua dolça | freshwater biology (The scientific study or the characteristic life processes of living organisms found in a natural body of water that does not contain significant amounts of dissolved salts and minerals, such as a lake or river) | |
| biologia de l'aire | aerobiology (The study of the atmospheric dispersal of airborne fungus spores, pollen grains, and microorganisms; and, more broadly, of airborne propagules of algae and protozoans, minute insects such as aphids, and pollution gases and particles which exert specific biologic effects) | |
| biologia del sòl | soil biology (The study of the living organisms, mainly microorganisms and microinvertebrates which live within the soil, and which are largely responsible for the decomposition processes vital to soil fertility) | |
| biologia humana | human biology (The study of human life and character) | |
| biologia marina | marine biology (A branch of biology that deals with those living organisms which inhabit the sea) |
