Speaking of the indoor air pollution that decoration may bring, such as formaldehyde, people are talking about pollution. Zhao Yeting, public health department of Dongcheng District Center for Disease Control and Prevention, pointed out that artificial boards such as plywood, blockboard, medium density fiberboard, and particleboard used for interior decoration will indeed contain formaldehyde, and will cause indoor air pollution. At the same time, all use of environmentally-friendly building materials is not 100% assured, because we must also consider a "environmental capacity" problem.
Zhao Yeting reminded that many building materials now claim to be “green building materialsâ€. In fact, their pollution is only lower than the national limit. Therefore, during the renovation, the decoration company must request the decoration company to present the test report of the relevant materials in order to understand the actual environmental protection indicators. When the materials are shipped to the construction site, it is necessary to check carefully whether the materials are in accordance with the agreement in the contract. Even green materials cannot be used arbitrarily, because the environmental performance of green building materials is only relatively high, and it is still unable to achieve true environmental protection. In addition, even the use of environmentally-friendly building materials is not 100% assured, because we must also consider a "environmental capacity" problem. If the amount of environmental protection materials is too much, it will make it difficult for the chemical preparations to evaporate quickly, resulting in pollution superposition and decoration pollution. Therefore, to ensure the air quality of the house after renovation, environmental protection, decoration should be simple and better, decorative materials (even environmentally friendly materials) to be limited use. In addition, even if the decoration materials are as environmentally friendly as possible, the choice of furniture should also be considered because some harmful gases in the furniture also cause environmental pollution.
In addition to trying to choose environmentally-friendly building materials, simple decoration, and timely detection of formaldehyde pollution, it is also necessary to understand some tips for dealing with indoor air pollution. Zhao Yeting recommends that people living in new homes should first test the air in their homes before entering home, and then select appropriate treatment methods according to the conditions of harmful gases. The most economical and effective way to eliminate indoor pollutants is through ventilation. In addition, bamboo charcoal, activated carbon, negative ions, and photocatalysts that are currently on the market can also effectively control indoor air pollution. Bamboo charcoal, activated carbon, etc. are all based on the principle that carbon absorbs odors and adsorbs harmful gases to control indoor air pollution. The cost is low, and there are no toxic side effects but the effect is slow. This is used as a long-term treatment method for indoor air pollution that is slightly excessive. Negative ions will quickly oxidize harmful gases such as benzene and formaldehyde to negative ions, which will be reduced to oxygen, water, and carbon dioxide when combined with air. This method can be used regularly. The photocatalyst is newly introduced from abroad and used in many applications. It is effective for heavy pollution, but its price is also high, and it may cause minor secondary pollution, which will affect the paint surface of wallpaper and wooden furniture. Also consider the use of pure plant scavenger extracted from plants, or put some anti-pollution flowers and plants in the room can also play an "air purifier" role, such as ivy, spider plant, Arisa leaf, Cactus, aloe vera, tiger skin, etc., have the function of absorbing formaldehyde and purifying the air.
