| Terms for subject Environment (6671 entries) |
| oxidizable material (Substance that can undergo a chemical reaction with oxygen) | oxidálható anyag | |
| oxygen (A gaseous chemical element; an essential element in cellular respiration and in combustion processes; the most abundant element in the earth's crust and about 20% of the air by volume) | oxigén | |
| oxygen content (Amount of oxygen contained in a solution) | oxigéntartalom | |
| oxygen deficiency (No definition needed) | oxigénhiány | |
| oxygenation (Treating with oxygen) | oxigéndúsítás | |
| oyster farming (There are two types of oyster farming: suspension culture, in which oysters are grown off bottom, in floating trays, is a labor-intensive form of cultivation that requires continuous tending and cleaning of both gear and shellfish, and bottom culture, which is similar to conventional crop farming on land; it involves selecting areas of the sea floor that provide a natural food supply, necessary currents, minimum exposure to predators, and proper temperature and then "seeding" the bottom with shellfish stock that are left to grow to market size. Then they are harvested with a bottom drag from a boat. Both suspension culture and bottom culture depend on natural food supplies for growing the shellfish being raised) | osztrigatenyésztés | |
| ozone (An allotropic form of oxygen containing three atoms in the molecule. It is a bluish gas, very active chemically, and a powerful oxidizing agent. Ozone is formed when oxygen or air is subjected to a silent electric discharge. It occurs in ordinary air in very small amounts only) | ózon | |
| ozone depletion potential (A factor that reflects the ozone depletion potential of a substance, on a mass per kilogram basis, as compared to chlorofluorocarbon-11 (CFC-11). Such factor shall be based upon the substance's atmospheric life time, the molecular weight of bromine and chlorine, and the substance's ability to be photolytically disassociated, and upon other factors determined to be an accurate measure of relative ozone depletion potential) | ózonréteg elvékonyodási potenciál | |
| ozone killer | ózonkárosító anyag | |
| ozone layer (The general stratum of the upper atmosphere in which there is an appreciable ozone concentration and in which ozone plays an important part in the radiative balance of the atmosphere) | ózonréteg | |
| 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) | ózonréteg elvékonyodása | |
| ozone-depleting substance | ózonkárosító anyag | |
| ozonization (The process of treating, impregnating or combining with ozone) | ózonizálás | |
| packaged | csomagolt | |
| packaging (All products made of any materials of any nature to be used for the containment, protection, handling, delivery and presentation of goods, from raw materials to processed goods, from the producer to the user or the consumer) | csomagolás | |
| packaging waste (Waste comprised of materials, or items, used to protect, contain, or transport a commodity or product and usually considered a type of consumer waste) | csomagolóanyag hulladék | |
| packing industry (No definition needed) | csomagolóipar | |
| paint (A mixture of pigment and a vehicle, such as oil or water, that together form a liquid or paste that can be applied to a surface to provide an adherent coating that imparts colour to and often protects the surface) | festék | |
| paint room (A portion of space within a commercial establishment that is used for applying coloring substances to certain products or materials, providing a decorative or protective coating) | festékszoba | |
| paint shop (A shop where paint and related items are sold) | festékbolt |
