Our people's lives are getting better and better now, but our pollution problem is getting worse and worse. Not only in the street, but also more serious is our indoor air pollution, then the indoor air pollutants , below Let everyone see. In fact, in addition to bacterial viruses such as measles, indoor air pollution is still a lot. Health authorities in Europe and the United States point out that indoor air pollution is two to five times more severe than outdoor air pollution (up to 100 times in the worst case). More than 1 million people die of chronic obstructive pulmonary disease each year due to indoor air pollution. 1. Decoration pollution is a unique and particularly serious type of pollution in China. The main pollutant produced is called volatile organic compounds (TVOC). Harmful gases that cause familiar indoor air pollution, such as formaldehyde, benzene, toluene, and xylene, are also in the TVOC category. 2. Under normal circumstances, the main bacteria and viruses in the room are Legionella and measles viruses. These bacteria and viruses can spread on the dust in the air. Through activities such as talking, coughing, sneezing, etc., pathogenic microorganisms in the mouth, throat, and lungs can be sprayed into the air by droplets and spread to others. For example, colds or influenza are usually spread from person to person through aerosols of body fluids. 3. In many areas of China, the construction of residential buildings, office buildings, hotels, restaurants, etc., is often artificially added to the concrete with high alkali cement expansion agent and urea-containing concrete antifreeze and other admixtures to prevent concrete in winter. It was cracked during construction, which greatly improved the construction progress. These admixtures containing a large amount of ammonia substances are slowly released into the wall by the change of environmental factors such as humidity and temperature in the wall, resulting in a large increase in the concentration of ammonia in the indoor air. 4. Pollution from indoors: Main sources of formaldehyde: 1 Wood-based panels are the most used materials for interior decoration. At present, the commonly used binders in the production of wood panels at home and abroad are urea-formaldehyde resins. The main raw materials are formaldehyde, urea and others. Excipients: 2 followed by new combination furniture and decoration materials and furniture in the plywood, large core board, MDF, particle board (fragment board) of the binder in the heat, decompression of formaldehyde is released; 3 with formaldehyde Preservative coatings, chemical fiber carpets, makeup crystals and other products; 4 indoor smoking. 5. Gas pollutants. Volatile organic compounds (VOCs) are the most important components, as well as O3, CO, CO2, NOx, and radioactive elements ruthenium (Rn) and its daughters. Especially when indoor ventilation conditions are poor, these gas pollutants will accumulate indoors, the concentration will increase, and some concentrations may exceed the hygienic standard by several times, causing serious indoor air pollution. 6. Indoor dust, burning particles, droplets and other pollutants, combined with indoor air light ions to form heavy ions. The former can only remain for 1 minute in dirty air, while the latter can remain for 1 hour, thus strengthening the adverse effects of heavy ions: headache, upset, fatigue, elevated blood pressure, mental disability, loss of attention, reduced ability to work Insomnia, etc. Now that everyone understands us, the indoor air is not good, and it will bring many dangers to everyone. I think you also know what indoor air pollutants are! Then we should pay attention to it later. The above content is told by the decoration home network, I would like to know more about the decoration, please pay more attention to us. Thank you!
