Indoor air quality(IAQ) is one of the fundamental elements affecting people's health and well-being. Currently, there is a lack of awareness among people about the quantification, identification, and possible health effects of IAQ. Airborne pollutants such as volatile organic compounds(VOCs), particulate matter(PM), sulfur dioxide(SO₂), carbon monoxide(CO), nitrous oxide(NO), polycyclic aromatic hydrocarbons(PAHs), microbial spores, pollen, allergens, etc. primarily contribute to IAQ deterioration.  3, record 1, English, - indoor%20air%20quality

Record number: 9, Textual support number: 1 CONT

Photosynthesis is the chemical process where plants and some bacteria can capture and organically fix the energy of the sun.... The main product of photosynthesis is a carbohydrate, such as the sugar glucose, and oxygen which is released to the atmosphere. All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight. This chemical reaction is catalyzed by chlorophyll acting in concert with other pigment, lipid, sugars, protein, and nucleic acid molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.  3, record 9, English, - photosynthesis

The MLS detects naturally occurring microwave thermal emissions from Earth's limb to create vertical profiles of atmospheric gasses, temperature, pressure and cloud ice. MLS looks 90° from the angle of UARS’ [Upper Atmosphere Research Statellite] orbit. Thermal radiation enters the instrument through a three-mirror antenna system. The antenna mechanically scans in the vertical plane through the atmospheric limb every 65. 5 seconds. The scan covers a height range from the surface up to 90 km(55 miles). Upon entering the instrument, the signal from the antenna is separated into three signals for processing by different radiometers. The 63-GHz radiometer measures temperature and pressure. The 183-GHz radiometer measures water vapor and ozone. The 205-GHz radiometer measures ClO, ozone, sulfur dioxide, nitric acid and water vapor.  2, record 25, English, - microwave%20limb%20sounder

The Gas Analyzer System for Metabolic Analysis Physiology(GASMAP) device is used to monitor and analyze inhaled and exhaled breath streams to determine their gas concentrations. The primary gases of interest are nitrogen(N²), oxygen(O²), carbon dioxide(CO²), argon(Ar), acetylene(C²H²), sulfur hexafluoride(SF⁶), helium(He), and carbon monoxide(C¹⁸ O). The GASMAP flight hardware consists of two components : an analyzer module and a calibration module, both of which are housed in drawers inside Spacelab. The analyzer module contains all the sensor and electronic hardware of the GASMAP.  3, record 43, English, - gas%20analyzer%20system%20for%20metabolic%20analysis%20physiology

Lorsque les CFC (chlorofluorocarbones), le HCFC ou le halon (Dymel ou Genetron), ou le chlorure de méthylène entrent en contact avec une cigarette allumée, des flammes nues ou des surfaces métalliques incandescentes, ils se décomposent rapidement et produisent de l'acide chlorhydrique, de l'acide fluorhydrique, du formaldéhyde ou de l'halogénure de carbonyle (PHOSGENE COCl2) qui est un poison.  2, record 44, French, - halog%C3%A9nure%20de%20carbonyle
