TVOC in the air three kinds of 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, acute damage to the human body. TVOC may have odor detection governance formaldehyde stone, irritating, 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 stone formaldehyde detection governance join, dizziness, headache, drowsiness, weakness, chest tightness and other symptoms; also may affect the digestive stone formaldehyde detection CMA qualification , loss of appetite, nausea, severe cases can damage the liver and hematopoietic system, there allergic reaction. Office and home air ammonia expert judgment come mainly from concrete admixtures used in construction, there are two: one is from the winter construction cement concrete antifreeze added urea, etc., due to In the laminates and cement stone in addition to formaldehyde, released more slowly, so there will be a long time to the living room. This phenomenon is more common in the north, such as the case of ammonia pollution Beijing New Town, is the concrete antifreeze containing urea used in the winter due to the volatile construction; the other is to increase the solidification rate of concrete, the use of high alkali concrete expansion agents and early strength agent. Ammonia pollution in the southern region, mainly from here. The use of concrete admixtures, help to improve the strength and speed of construction of concrete, the country has strict standards and technical specifications in this regard. Under normal circumstances, does not pollute indoor air situation, but in recent years, Beijing extensive use of high-alkali concrete expansion and concrete antifreeze containing urea, which contains large amounts of ammonia additive substances in the wall with changes in temperature and humidity and other environmental factors, and reduced to the slow release of ammonia from the wall, causing the concentration of ammonia in indoor air continues to grow.
