Terms for subject Environment (5171 entries)
klimatologi climatology (That branch of meteorology concerned with the mean physical state of the atmosphere together with its statistical variations in both space and time as reflected in the weather behaviour over a period of many years)
klimatype climate type (Weather conditions typical of areas roughly corresponding to lines of latitude)
klimavern climate protection (Precautionary actions, procedures or installations undertaken to prevent or reduce harm from pollution to natural weather conditions or patterns, including the prevailing temperature, atmospheric composition and precipitation)
klippe cliff (A steep coastal declivity which may or may not be precipitous, the slope angle being dependent partly on the jointing, bedding and hardness of the materials from which the cliff has been formed, and partly on the erosional processes at work. Where wave attack is dominant the cliff-foot will be rapidly eroded and cliff retreat will take place, especially in unconsolidated materials such as clays, sands, etc., frequently leaving behind an abrasion platform at the foot of the cliff)
kloakk sewage (Any liquid-born waste that contains animal or plant matter in suspension or solution, soils and storm water, or chemicals in solution)
kloakkbehandlingssystem sewage treatment system (Sewage treatment comes in two stages - primary and secondary treatment. The primary stage involves a process of screening solids from sewage, leaving a sludge and relatively clear water for further treatment or for disposal into rivers, the sea or on to the land. In the secondary stage the sludge is stirred constantly in vast tanks to get more oxygen into the mixture, allowing bacteria to break down the organic matter and leave a harmless residue that falls as a sediment to the bottom of the tank. After processing, the clear water on top of the tank is discharged into rivers and the sediment is used as landfill or discharged at sea)
kloakkdisponering sewage disposal
kloakkslam sewage sludge (A semi-liquid waste with a solid concentration in excess of 2500 parts per million, obtained from the purification of municipal sewage)
kloakkspredningsforbud sewage spreading prohibition (Prohibition of spreading sewage sludge on land to prevent accumulation of toxic heavy metals in excessive quantities)
kloning cloning (The production of genetically identical individuals from a single parent. Cloning plants usually involves plant cell culture. Cloning animals is more difficult and relays on some manipulation of their normal reproductive cycle. A clone is a group of organisms of identical genetic constitution, unless mutation occurs, produced from a single individual by asexual reproduction, parthenogenesis or apomixis)
klor chlorine (A very reactive and highly toxic green, gaseous element, belonging to the halogen family of substances. It is one of the most widespread elements, as it occurs naturally in sea-water, salt lakes and underground deposits, but usually occurs in a safe form as common salt (NaCl). Commercially it is used in large quantities by the chemical industry both as an element to produce chlorinated organic solvents, like polychlorinated biphenyls (PCBs), and for the manufacture of polyvinyl chloride plastics, thermoplastic and hypochlorite bleaches. Chlorine was the basis for the organochlorine pesticides, like DDT and other agricultural chemicals that have killed wildlife. The reactivity of chlorine has proved disastrous for the ozone layer and has been the cause of the creation of the ozone hole, which was first detected in the Southern Hemisphere over Antarctica and then over the Northern Hemisphere)
klorering chlorination (The application of chlorine to water, sewage or industrial wastes for disinfection or other biological or chemical purposes)
kloreten chloroethylene (A flammable, explosive gas with an ethereal aroma; soluble in alcohol and ether, slightly soluble in water; boils at -14° C; an important monomer for polyvinyl chloride and its copolymers; used in organic synthesis and in adhesives)
klorfenol chlorophenol (Major group of chlorinated hydrocarbons, pesticides and biocides which account for a very high percentage of the non-agricultural pesticide use, such as anti-rotting agents in non-woollen textiles and wood preservatives. The chlorophenols act as biocides by inhibiting the respiration and energy-conversion processes of the microorganisms. They are toxic to man above 40 parts per million, to fish above 1 ppm, whilst concentrations as low as one part per thousand million can taint water)
klorfluorkarbon chlorofluorocarbon (Gases formed of chlorine, fluorine, and carbon whose molecules normally do not react with other substances; they are therefore used as spray can propellants because they do not alter the material being sprayed)
klorhydrokarbon chlorinated hydrocarbon (A class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, mirex, hexachloride, and toxaphene. In insects and other animals these compounds act primarily on the central nervous system. They also become concentrated in the fats of organisms and thus tend to produce fatty infiltration of the heart and fatty degeneration of the liver in vertebrates. In fishes they have the effect of preventing oxygen uptake, causing suffocation. They are also known to slow the rate of photosynthesis in plants. Their danger to the ecosystem resides in their rate stability and the fact that they are broad-spectrum poisons which are very mobile because of their propensity to stick to dust particles and evaporate with water into the atmosphere)
klorid chloride (A compound which is derived from hydrochloric acid and contains the chlorine atom in the -1 oxidation state)
klorofyll chlorophyll (A green pigment, present in algae and higher plants, that absorbs light energy and thus plays a vital role in photosynthesis. Except in Cyanophyta (blue-green algae), chlorophyll is confined to chloroplasts. There are several types of chlorophyll, but all contain magnesium and iron. Some plants (e.g., brown algae, red algae, copper beech trees) contain additional pigments that masks the green of their chlorophyll)
klorose chlorosis (A disease condition of green plants seen as yellowing of green parts of the plants)
knappcellebatteri button-cell battery (A tiny, circular battery made for a watch or for other microelectric applications)
