| nedbryter |
saprobe (Referring to the classification of organisms according to the way in which they tolerate pollution) |
|
| nedbryting |
degradation (A type of organic chemical reaction in which a compound is converted into a simpler compound in stages) |
|
| nedbryting av forurensning |
pollutant degradation (The physical, chemical or biological breakdown of a complex polluting material into simpler components) |
|
| nedbryting av ozonlaget |
ozone layer depletion (The fragile shield of ozone is been damaged by chemicals released on earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons which are used in refrigerators, aerosols, and as cleaners in many industries, and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine. Over the past 30 years ozone levels over parts of Antarctica have dropped by almost 40% during some months and a "hole" in ozone concentrations is clearly visible in satellite observations) |
|
| nedbrytingsindeks |
saprobic index (Indication or measure of the level of organic pollution) |
|
| nedbrytingsprodukt |
degradation product (Those chemicals resulting from partial decomposition or chemical breakdown of substances) |
|
| nedbrytning |
decomposition (The more or less permanent breakdown of a molecule into simpler molecules or atoms) |
|
| nedbør |
atmospheric precipitation (The settling out of water from cloud in the form of dew, rain, hail, snow, etc.) |
|
| nedbørfelt |
catchment area (1. An area from which surface runoff is carried away by a single drainage system. 2. The area of land bounded by watersheds draining into a river, basin or reservoir) |
|
| nedbørfremkalling |
precipitation enhancement (Increase of precipitation resulting from changes in the colloidal stability of clouds. This can be either intentional, as with cloud seeding, or unintentional, as with air pollution, which increases aerosol concentrations and reduces sunlight) |
|
| nedfall |
fallout (The descent of airborne solid or liquid particles to the ground, which occurs when the speed at which they fall due to gravity exceeds that of any upward motion of the air surrounding them) |
|
| nedlagt militært område |
disused military site (Military site where all activity has ceased. Such areas, being extremely well sheltered against outside disturbances and in many ways less affected by human landuse than many other open landscapes, can contain significant natural habitats and rare or endangered wildlife. Abandoned military territories constitute an important source of natural landscapes to be managed and restored in an environmentally sound way) |
|
| nedleggelse |
closing down (The cessation, discontinuation or breaking-off of a business transaction, lease, contract or employment arrangement, usually before its anticipated or stipulated end) |
|
| nedsenking av avfall |
sinking of waste (A manner of waste disposal in which refuse or unwanted material is dumped or submerged beneath the surface of a body of water) |
|
| nekrose |
necrosis (The pathologic death of living tissue in a plant or animal) |
|
| nematode |
nematode (A group of unsegmented worms which have been variously recognized as an order, class, and phylum) |
|
| nervesystem |
nervous system (A coordinating and integrating system which functions in the adaptation of an organism to its environment; in vertebrates, the system consists of the brain, brainstem, spinal cord, cranial and peripheral nerves, and ganglia) |
|
| nes |
headland (A cape or promontory jutting seawards from a coastline, usually with a significant sea cliff; geography) |
|
| netto ressurstapping |
net resource depletion (The total decrease in the amount of natural materials available for use by humans and other living beings) |
|
| nettverkspolitikk |
netting policy (All emission sources in the same area that are owned or controlled by a single company are treated as one large source, thereby allowing flexibility in controlling individual sources in order to meet a single emissions standard; emissions trading) |
