Venturi scrubbers can be used for removing gaseous pollutants; however, they are not used when removal of gaseous pollutants is the only concern. The high inlet gas velocities in a Venturi scrubber result in a very short contact time between the liquid and gas phases. This short contact time limits gas absorption. However, because Venturis have a relatively open design compared to other scrubbers, they are still very useful for simultaneous gaseous and particulate pollutant removal...  2, record 1, English, - Venturi%20scrubber

Un laveur Venturi est composé principalement par un poumon centrifuge (ayant une fonction de séparateur de la fraction solide et de celle liquide) et d'une colonne Venturi. Venturi est constitué d'un cylindre dont la section médiane présente une diminution de diamètre.  2, record 1, French, - laveur%20Venturi

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, record 2, English, - pure%20air

A term loosely used to designate : 1) the introduction into a medium of a pollutant or of a material which the environment can not handle, degrade or disperse; 2) the presence of pollutants observed in a medium(involving an increase in the volume of materials already present in natural ecosystems, as well as those poisons and chemicals that are not normally present in nature) ;and 3) the undesirable modification of the composition of a liquid solid or gaseous medium which results from this introduction.  2, record 3, English, - pollution

In water pollution, the term "contamination" is often used as a synonym, as shown by the following definition, taken in source IWATE (Glossary of water and wastewater control engineering, by the American Public Health Association): "The introduction into water of microorganisms, chemicals, wastes, or wastewater in a concentration that makes the water unfit for its intended use." However, a distinction should be made between "pollution" and "contamination": the latter implies a health danger (particularly to humans). Compare "(air) pollutant", "(air) contaminant" and "contamination".  2, record 3, English, - pollution
