Infrared Analyzers : Organic molecules, in general, contain interatomic valence bonds which exhibit characteristic resonance frequencies. These can be identified in the absorption spectrum of the material in gaseous form. Such information can be used to study the structure of complex molecules. In addition to research, infrared analyzers are used extensively for process quality control [e. g. in pollution control, in food technology].  3, fiche 2, Anglais, - infrared%20analyzer

Air (relatively) devoid of solid, liquid or gaseous pollutant materials.  3, fiche 3, Anglais, - pure%20air

Record number: 3, Textual support number: 1 CONT

The composition of air is variable with respect to several of its components(e. g., CH₄, CO₂, H₂O) so "pure" air has no precise meaning; it is commonly considered to be air which is free of dust, [hydrometeors, ] aerosols, and reactive gaseous contaminants of anthropogenic origin [such as industrial effluents].... Relative clean air which is free of most reactive anthropogenic pollution(NO, NO₂, SO₂, non-methane hydrocarbons, etc.), often used as a reference sample in the calibration and operation of instruments, is purchased under the designation of zero air.  4, fiche 3, Anglais, - pure%20air

[The] so-called "pure" air is a mixture of gases containing about 78 percent nitrogen; 21 percent oxygen; less than 1 percent of carbon dioxide, argon, and other inert gases; and varying amounts of water vapor.  5, fiche 3, Anglais, - pure%20air

L'air est un mélange de gaz constituant l'atmosphère qui entoure la terre. L'air pur est composé de 21 % d'oxygène et de 78 % d'azote par volume, en plus de quantités infimes d'autres gaz comme l'argon, le gaz carbonique et la vapeur d'eau.  3, fiche 3, Français, - air%20pur

Fluorines occur as either gaseous or solid emissions of such industrial processes as the manufacture of fertilizer and aluminum, iron ore smelting, and ceramics production. Airborne fluorides can damage vegetation, with some plants concentrating and accumulating these fluorides, and the livestock eating the plants as forage can become ill.(...) Close to an industrial source of fluoride pollution however, many may be subjected to eye and skin irritation, inflammation of the respiratory tract, and breathing difficulties.  2, fiche 4, Anglais, - fluoride%20pollution

Fluoridated water is credited with reducing the occurrence of dental decay in children. In excess quantities, fluorine may be a water pollutant, appearing in industrial waste water. It may also be an air pollutant resulting from manufacturing processes. Fluorides are phytotoxic.  3, fiche 4, Anglais, - fluoride%20pollution

Des adjectifs comme "nitré, soufré, azoté, fluoré" serviront couramment à désigner les différentes pollutions causées par des produits chimiques le nitrate, le soufre, l'azote et le fluor ainsi que par leurs composés. Le lien, entre le déterminé et son déterminant, ressortirait cependant davantage si on disait plutôt "pollution par le nitrate, par le soufre, par l'azote, par le fluor".  4, fiche 4, Français, - pollution%20fluor%C3%A9e
