The main source of TVOC outdoors, mainly from fuel combustion and transport: In the interior is mainly from coal and natural gas combustion products, smoke, fumes and other heating and cooking, construction and decoration materials Jixi formaldehyde detection CMA qualification, furniture, household appliances, cleaning agents and the body's own emissions. There are nearly a thousand species. In the interior decoration process, VOC mainly from paints, coatings and adhesives. According to reports, indoor TVOC concentrations typically between 0.2mg / m3 to 2mg / m3, while the decoration in improper construction, or even tens of times higher. Indoor various aromatics and alkanes mainly from vehicle exhaust (76% -92%). General Paint towel TVOC content 0.4-1.0mg / m3. After Lily et al point out, as a result of strong volatility TVOC, under normal circumstances Jixi formaldehyde detection governance, within 10 hours after construction paint, 90% can be volatile, and the solvent in the paint drying process TVOC released only 25 total %. Because benzene and BTEX is an important component of Jixi TVOC formaldehyde detection control agents, so some people only detect TVOC, without detection of benzene and BTEX: However, there are only a total of benzene detected without detection TVOC: There are some Both units are detected. It mainly depends on the requirements and conditions. TVOC higher detection technology and equipment requirements, usually by gas chromatography, but also by Fourier transform infrared spectroscopy, fluorescence spectroscopy, ion chromatography and reflection interference spectroscopy method. They all appear to trace and trace levels, so easily overlooked. They mainly come from: organic solution: such as paints, water paints, adhesives, cosmetics, detergents, rubber caulking; Building materials: such as plywood, foam insulation materials, plastic sheets; interior decoration materials TVOC in the air three organic pollutants (polycyclic aromatic hydrocarbons, volatile organic compounds and aldehydes) in a more serious impact. TVOC toxicity, irritation, carcinogenicity and special odor resistance, affects the skin and mucous membranes Jixi addition to formaldehyde, acute damage to the human body. TVOC may have odor, irritation, and some genotoxic compounds. Indoor TVOC mainly by distributing building materials, interior decoration materials and living and office supplies out. Building materials such as plywood, foam insulation materials, plastic sheets; interior decoration materials, paints, coatings, adhesives, wallpaper, carpets; life used in cosmetics, detergents, etc; office supplies mainly refers to the ink, copiers, typewriters, etc; TVOC can cause the level of immune disorders affecting the central nervous system function, dizziness, headache, drowsiness, weakness, chest tightness and other symptoms; also may affect the digestive system, loss of appetite, nausea, severe cases can damage liver and hematopoietic system, there allergic reaction.
