| Terms for subject Environment (6279 entries) |
| dávka záření | radiation dose (The total amount of radiation absorbed by material or tissues, in the sense of absorbed dose, exposure dose, or dose equivalent) | |
| dávkování | dosage (The amount of a substance required to produce an effect) | |
| DDT | DDT (A persistent organochlorine insecticide, also known as dichlorodiphenyltrichloroethane, that was introduced in the 1940s and used widely because of its persistence (meaning repeated applications were unnecessary), its low toxicity to mammals and its simplicity and cheapness of manufacture. It became dispersed all over the world and, with other organochlorines, had a disruptive effect on species high in food chains, especially on the breeding success of certain predatory birds. DDT is very stable, relatively insoluble in water, but highly soluble in fats. Health effects on humans are not clear, but it is less toxic than related compounds. It is poisonous to other vertebrates, especially fish, and is stored in the fatty tissue of animals as sublethal amounts of the less toxic DDE. Because of its effects on wildlife its use in most countries is now forbidden or strictly limited) | |
| decentralizace | decentralisation (Basic organizational leadership concept and process of shifting and delegating power and authority from a higher level to subordinate levels within the administrative/managerial hierarchy in order to promote independence, responsibility, and quicker decision-making in applying or interpreting policies and procedures to the needs of these levels) | |
| dechlorace | dechlorination (Removal of chlorine from a substance) | |
| decibel | decibel (A unit used to express relative difference on power, usually between acoustic or electric signals, equal to ten times the common logarithm of the ratio of the two level) | |
| dědictví biologické | biological heritage (The inheritance and preservation of the earth's or a particular region's balanced, integrated functionality as a natural habitat, with special concern for the water resources necessary to maintain the ecosystem) | |
| dědictví kulturní | cultural heritage (The inherited body of beliefs, customs, artistic activity and knowledge that has been transmitted by ancestors) | |
| dědictví přírodní | natural heritage (Generally, the world's natural resources as handed down to the present generation, and specifically, the earth's outstanding physical, biological and geological formations, and habitats of threatened species of animals and plants and areas with scientific, conservation or aesthetic value) | |
| dědictví rostlin | plant heritage (The sum of the earth's or a particular region's herb, vegetable, shrub and tree life viewed as the inheritance of the present generation, especially plant species deemed worthy of preservation and protection from extinction) | |
| dědictví živočichů | animal heritage (The sum of the earth's or a particular region's non-human, non-vegetable, multicellular organisms viewed as the inheritance of the present generation, especially animal species deemed worthy of preservation and protection from extinction) | |
| deficit kyslíku | oxygen deficiency (No definition needed) | |
| degradace | degradation (A type of organic chemical reaction in which a compound is converted into a simpler compound in stages) | |
| degradace chemická | chemical degradation (The act or process of simplifying or breaking down a molecule into smaller parts, either naturally or artificially) | |
| degradace pomocí světla | photodegradation (The capability of being decomposed by prolonged exposure to light) | |
| degradace půdy | soil degradation (Soil may deteriorate either by physical movement of soil particles from a given site or by depletion of the water-soluble elements in the soil which contribute to the nourishment of crop, plants, grasses, trees, and other economically usable vegetation. The physical movement generally is referred to as erosion. Wind, water, glacial ice, animals and tools in use may be agents of erosion) | |
| dehet | tar (A viscous material composed of complex, high-molecular-weight, compounds derived from the distillation of petroleum or the destructive distillation of wood or coal) | |
| dekantace | racking (The mechanical dewatering of a wet solid by pouring off the liquid without disturbing the underlying sediment or precipitate) | |
| dekarbonizace ekonomiky | decarbonisation of the economy | |
| dekontaminace | decontamination (The removing of chemical, biological, or radiological contamination from, or the neutralizing of it on a person, object, or area) |
