| biologisk dam |
lagoon (A body of water cut off from the open sea by coral reefs or sand bars) |
|
| biologisk egenskap |
biological attribute (Properties or features belonging to living organisms) |
|
| biologisk filter |
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) |
|
| biologisk filtrering |
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) |
|
| biologisk forurensning |
biological pollution (Disturbance of the ecological balance by the accidental or deliberate introduction of a foreign organism, animal or plant species into an environment) |
|
| biologisk indikator |
biological indicator (A species or organism that is used to grade environmental quality or change) |
|
| biologisk kontaminering |
biological contamination (The presence in the environment of living organisms or agents derived by viruses, bacteria, fungi, and mammal and bird antigens that can cause many health effects) |
|
| biologisk kretsløp |
biological cycle (A series of transformations or biological events which follow one after the other one, reaching at the end of the cycle the initial conditions, as in the life cycle of many animal and plant organisms) |
|
| biologisk mangfold |
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) |
|
| biologisk marin ressurs |
living marine resource |
|
| biologisk nedbrytbarhet |
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) |
|
| biologisk nedbrytbart forurensende stoff |
biodegradable pollutant (A pollutant which can be converted by biological processes into simple inorganic molecules) |
|
| biologisk nedbryting |
biodegradation (Breaking down of a substance by microorganisms) |
|
| biologisk nitrogenfiksering |
biological nitrogen fixation |
|
| biologisk overvåking |
biological monitoring (The direct measurement of changes in the biological status of a habitat, based on evaluations of the number and distribution of individuals or species before and after a change) |
|
| biologisk produksjon |
biological production (1. The amount and rate of production which occur in a given ecosystem over a given time period. It may apply to a single organism, a population, or entire communities and ecosystems. 2. The quantity of organic matter or its equivalent in dry matter, carbon, or energy content which is accumulated during a given period of time) |
|
| biologisk prosess |
biological process (Processes concerning living organisms) |
|
| biologisk rensing |
biological treatment (Process that uses microorganisms to decompose organic wastes either into water, carbon dioxide, and simple inorganic substances, or into simpler organic substances, such as aldehydes and acids. The purpose of a biological treatment system is to control the environment for microorganisms so that their growth and activity are enhanced, and provide a means for maintaining high concentration of the microorganisms in contact with the wastes) |
|
| biologisk reservat |
biological reserve (An area of land and/or of water designated as having protected status for purposes of preserving certain biological features. Reserves are managed primarily to safeguard these features and provide opportunities for research into the problems underlying the management of natural sites and of vegetation and animal populations. Regulations are normally imposed controlling public access and disturbance) |
|
| biologisk ressurs |
biological resource (Wild organisms harvested for subsistence, commerce, or recreation (such as fish, game, timber or furbearers); domesticated organisms raised by agriculture, aquaculture, and silviculture; and ecosystems cropped by livestock) |
