There are many factors that cause indoor pollution to cause pollution. Experts say that as long as you can grasp the three levels of materials, construction and testing during the decoration process, you can basically prevent decoration pollution.

Li Yaqing, deputy director of the Environmental Testing Center of Shijiazhuang City, believes that renovation must first be done with good materials. Li Yaqing said that in recent years, the state has formulated and promoted the standards for harmful substances in decoration materials, which has effectively cracked down on the excessive standards of harmful substances. The over-standard decoration materials have been restricted in the market. However, it cannot be considered that products that pass the inspection of hazardous substances can be used at will. Some materials, such as MDF, plywood, etc., although the products are all qualified, if used excessively, the harmful substances volatilized are still likely to exceed the safety standards and cause harm to the human body. In addition, new materials appear in the decoration market, making it difficult to clearly understand which materials contain harmful substances and the degree of harm. Based on the above considerations, he suggested that people should establish a rational sense of decoration, do not blindly pursue luxury decoration, but should advocate simple and harmonious, moderate decoration, and minimize the harm caused by decoration materials.

The construction process is also critical to prevent decoration pollution. Li Yaqing said that the decoration construction process should be carried out under well-ventilated conditions. Good ventilation can reduce the concentration of harmful substances in the air, and it is also beneficial to shorten the volatilization period of harmful substances and accelerate the concentration of harmful substances in the air to a safe range. Water-soluble materials and natural materials should be used as much as possible during the construction process. The use of water-soluble materials will greatly reduce the amount of organic volatiles, especially the amount of benzene, toluene and xylene.

After the renovation is completed, the professional environmental inspection department should be promptly inspected to check the indoor air quality after renovation, to ensure that all indicators are qualified before entering. At present, environmental protection, sanitation and epidemic prevention, construction and other departments have carried out environmental testing services. They can ask these departments to conduct tests and find that harmful substances exceed the standard and should be treated in time.

In addition, there should be as few harmful items as possible in the home. For example, after waxing the floor, the total volatile organic compounds (TVOC) in the room will increase because the polish and liquid wax contain a lot of volatile organic compounds. Many people like to use fragrances and air fresheners. In fact, these products not only contain a lot of volatile organic compounds, but also some derivatives of benzene and benzene, which are harmful to human health.
