| Terms for subject Environment (5878 entries) |
| accumulation in body tissues | تراكم في أنسجة الجسم | |
| accumulator (A rechargeable device for storing electrical energy in the form of chemical energy, consisting of one or more separate secondary cells) | مُجَمِّع - مُراكِم | |
| acid (A compound capable of transferring a hydrogen ion in solution) | حمض | |
| acid deposition (A type of pollution which washes out of the atmosphere as dilute sulphuric and nitric acids. It tends to be a regional rather than a global phenomenon, linked to particular industrial activities and meteorological conditions. It includes rain, more than normally acidic snow, mist, sleet, fog, gas and dry particles. It upsets the balance of nature, disrupting ecosystems, and destroys forests and woodlands, plants and crops; kills aquatic life by altering the chemical balance of lakes and rivers and corrodes building materials and fabrics. The pollutants are caused principally by discharges from power station chimneys of sulphur dioxide and nitrogen oxides released by burning fossil fuels, coal and oil) | ترسيب حمضي | |
| acid deposition | تَرَسُّبات حَمضية | |
| acid rain (Rain having a pH less than 5.6. The acidity results from chemical reactions occurring when water, sulphur dioxide, and nitrogen oxides, generally released by industrial processes, are chemically transformed into sulphuric and nitric acids) | مطر حمضي | |
| acidification (Addition of an acid to a solution until the pH falls below 7) | تحميض | |
| acidity (The state of being acid that is of being capable of transferring a hydrogen ion in solution) | حمضية | |
| acidity degree (The amount of acid present in a solution, often expressed in terms of pH) | درجة الحمضية | |
| acoustic comfort | ارتياح صوتي | |
| acoustic filter (A device employed to reject sound in a particular range of frequencies while passing sound in another range of frequencies) | مُرشِّح صوتي | |
| acoustic insulation (The process of preventing the transmission of sound by surrounding with a nonconducting material) | عزل صوتي | |
| acoustic level (Physical quantity of sound measured, usually expressed in decibels) | مستوى صوتي | |
| acoustic property (The characteristics found within a structure that determine the quality of sound in its relevance to hearing) | خاصية صوتية | |
| acoustical quality (The characteristics of a confined space that determines its ability to enable music and speech to be heard clearly within it) | الخاصية الصوتية | |
| acoustics (The science of the production, transmission and effects of sound) | صوتيات | |
| act (1. Something done voluntarily by a person, and of such a nature that certain legal consequences attach to it. 2. Documents, decrees, edicts, laws, judgments, etc.) | فعل | |
| actinide (A group of 15 radioactive elements some of which occur naturally while others are produced in nuclear reactions. They include plutonium, americium and neptunium. The health hazard presented by the actinides, if they are released into the environment, comes from the potency of their radioactive characteristics. They are alpha-emitters, and therefore can cause intense localized damage in tissues if absorbed into the body) | أكتينيد | |
| actinium (A radioactive element of the actinide series, occurring as a decay product of uranium. It is used as an alpha particle source and in neutron production) | أكتينيوم | |
| action group (A collection of persons united to address specific sociopolitical or socioeconomic concerns) | مجموعة عمل |
