chemical analysis The complex of operations aiming to determine the kinds of constituents of a given substance | kimyasal analiz |
chemical composition The nature and proportions of the elements comprising a chemical compound | kimyasal bileşim |
chemical contamination The addition or presence of chemicals to, or in, another substance to such a degree as to render it unfit for its intended purpose. Also refers to the result(s) of such an addition or presence | kimyasal kontaminasyon |
chemical corrosivity The tendency of a metal to wear away another by chemical attack | kimyasal aşındırma |
chemical decontamination Removal of chemical substances from a building, a watercourse, a person's clothes, etc. | kimyasal arındırma |
chemical degradation The act or process of simplifying or breaking down a molecule into smaller parts, either naturally or artificially | kimyasal bozulma |
chemical element elements and their compounds ; A substance made up of atoms with the same atomic number; common examples are hydrogen, gold, and iron | kimyasal element |
chemical engineering The branch of engineering concerned with industrial manufacture of chemical products. It is a discipline in which the principles of mathematical, physical and natural sciences are used to solve problems in applied chemistry. Chemical engineers design, develop, and optimise processes and plants, operate them, manage personnel and capital, and conduct research necessary for new developments. Through their efforts, new petroleum products, plastics, agricultural chemicals, house-hold products, pharmaceuticals, electronic and advanced materials, photographic materials, chemical and biological compounds, various food and other products evolve | kimya mühendisliği |
chemical fallout The sedimentation of chemical substances accumulated in the atmosphere as a result of industrial emissions | kimyasal serpinti |
chemical fertiliser Fertilizer manufactured from chemicals; excessive use of them can cause pollution, when all the chemicals are not taken up by the plants and the excess is leached out of the soil into rivers and may cause algal bloom | kimyasal gübre |
chemical in the environment The presence in the environment of any solid, liquid or gaseous material discharged from a process and that may pose substantial hazard to human health and the environment | ortamdaki kimyasal maddeler |
chemical industry Industry related with the production of chemical compounds. The chemical processing industry has a variety of special pollution problems due to the vast number of products manufactured. The treatment processes combine processing, concentration, separation, extraction, by-product recovery, destruction, and reduction in concentration. The wastes may originate from solvent extraction, acid and caustic wastes, overflows, spills, mechanical loss, etc. | kimya sanayi |
chemical installation Building where chemicals are manufactured | kimya tesisi |
chemical measurement of pollution The quantitative determination of the presence, extent or type of pollutant substances in the environment by studying the actions or reactions of known chemicals to those pollutants | çevre kirliliğinin kimyasal ölçümü |
chemical oceanography | kimyasal oşinografi |
chemical oxygen demand The quantity of oxygen used in biological and non-biological oxidation of materials in water; a measure of water quality | kimyasal oksijen ihtiyacı |
chemical pest control Control of plants and animals classified as pests by means of chemical compounds | zararlılarla kimyasal mücadele |
chemical plant Plants where basic raw materials are chemically converted into a variety of products | kimya fabrikası |
chemical policy | kimyasallar politikası |
chemical pollutant | kimyasal kirletici |
chemical pollution Pollution caused by substances of chemical nature, including chlorinated hydrocarbon pesticides, polychlorinated biphenyls, metals as mercury, lead, cadmium, arsenic, etc. | kimyasal kirlilik |
chemical process The particular method of manufacturing or making a chemical usually involving a number of steps or operations | kimyasal süreç |
chemical product A substance characterized by definite molecular composition | kimyasal ürün |
chemical property Properties of a substance depending on the arrangement of the atoms in the molecule, e.g. bio-availability, degradability, persistence, etc. | kimyasal özellik |
chemical reaction A change in which a substance is transformed into one or more new substances | kimyasal reaksiyon |
chemical reduction Chemical reaction in which an element gains an electron | indirgeme (kimya) |
chemical reduction Chemical reaction in which an element gains an electron | redüksiyon |
chemical risk Probability of harm to human health, property or the environment posed by contact with any substance of a defined molecular composition | kimyasal risk |
chemical structure The arrangement of atoms in a molecule of a chemical compound | kimyasal yapı |
chemical treatment Processes that alter the chemical structure of the constituents of the waste to produce either an innocuous or a less hazardous material. Chemical processes are attractive because they produce minimal air emissions, they can often be carried out on the site of the waste generator, and some processes can be designed and constructed as mobile units | kimyasal arıtma |
chemical treatment of waste | atıkların kimyasal arıtımı |
chemical waste Any by-product of a chemical process, including manufacturing processes. Often this by-product is considered a toxic or polluting substance | kimyasal atık |
chemical weapon Chemical agents of warfare include all gaseous, liquid or solid chemical substances which might be employed because of their direct toxic effects on man and animals. Chemical weapons also include the chemical's precursors, the munitions and devices designed to deliver them, and any equipment specifically designed for their use in warfare. Nerve agents (chemicals of the same family as organophosphorous insecticides) are the most lethal of the classical chemical warfare agents, killing by poisoning the nervous system and disrupting bodily functions. Other chemical weapons include blister agents, vesicants, choking agents, etc. | kimyasal silah |
