| Terms for subject Environment (6297 entries) |
| ملوث كيميائي | chemical pollutant | |
| ملوث للماء | water pollutant (A chemical or physical agent introduced to any body of water that may detrimentally alter the natural condition of that body of water and other associated bodies of water) | |
| ملوث مهلجن | halogenated pollutant (An organic compound bonded with one of the five halogen elements (astatine, bromine, chlorine, fluorine, and iodine). Several of these compounds contribute to reductions in the concentration of ozone in the stratosphere) | |
| ملوث هواء غازي | gaseous air pollutant (Uncondensed or volatile gases, usually comprised of chemical compounds, discharged to the atmosphere) | |
| ملوثات التحلل الحيوي | biodegradable pollutant (A pollutant which can be converted by biological processes into simple inorganic molecules) | |
| ملوثات التراكم الأحيائي | bioaccumulative pollutant (Pollutants that become concentrated in living organisms through the consumption of food or water) | |
| ملوثات التربة | soil pollutant (Solid, liquid and gaseous substances that detrimentally alter the natural condition of the soil) | |
| ملوثات حيوية | biological pollutant (Viruses, bacteria, fungi, and mammal and bird antigens that may be present in the environment and cause many health effects) | |
| ملوثات مجهرية | micropollutant (Pollutant which exists in very small traces in water) | |
| ملوحة التربة | soil salinity (Measurement of the quantity of mineral salts found in a soil. Many semi-arid and arid areas are naturally salty. By definition they are areas of substantial water deficit where evapotranspiration exceeds precipitation. Thus, whereas in humid areas there is sufficient water to percolate through the soil and to leach soluble materials from the soil and the rocks into the rivers and hence into the sea, in deserts this is not the case. Salts therefore tend to accumulate) | |
| ملوحة التربة | soil salination (The accumulation of soluble mineral salts near the surface of soil, usually caused by the capillary flow of water from saline ground water. Where the rate of surface evaporation is high, irrigation can exacerbate the problem by moistening the soil and causing water to be drawn from deeper levels as water evaporates from the surface. The evaporation of pure water leaves the salts behind, allowing them to accumulate, and they can reach concentrations that are toxic to plants, thus sterilizing the land) | |
| ملوحة الماء | water salinity (The degree of dissolved salts in water measured by weight in parts per thousand) | |
| ممارسات الغابات | forestry practice (The farming of trees to ensure a continuing supply of timber and other forest products. Foresters care for existing trees, protecting them from fire, pests and diseases, and felling where trees are overcrowded or dying and when ready for cropping. They also plant new areas (afforestation) and replant felled areas (reafforestation)) | |
| ممارسة التجارة المقيدة | restrictive trade practice (Business operation or action that confines or limits the free exchange of goods and services within a country or between countries, which may include discrimination, exclusive dealings, collusion agreements or price fixing) | |
| ممر | corridor (A physical linkage, connecting two areas of habitat and differing from the habitat on either side. Corridors are used by organisms to move around without having to leave the preferred habitat) | |
| ممر أخضر | green corridor (Avenues along which wide-ranging animals can travel, plants can propagate, genetic interchange can occur, populations can move in response to environmental changes and natural disasters, and threatened species can be replenished from other areas) | |
| ممر التزلج | ski run (A trail, slope, or course for skiing) | |
| ممر للحيوانات | animal corridor (Line corridors (roads, paths, and hedgerows) which lack interior habitat but may serve as movement groups for organisms. Corridors may also provide an efficient migratory pathway for animals. The presence or absence of breaks in a corridor may be a very important factor in determining the effectiveness of its conduit and barrier functions) | |
| ممشى | footpath (A narrow path for walkers only) | |
| ممشى تريُّض | hiking trail (A trail in the country along which one can walk, usually for pleasure or exercise) |
