Interior decoration pollution is an emerging environmental pollution. In simple terms, indoor decoration pollution refers to the pollution of the indoor environment caused by decoration activities. The following Xiaobian teach you a few tricks, so that everyone away from indoor decoration pollution problems. Interior decoration pollution source 1, volatile organic compounds Commonly-used decoration materials, such as paint, paint, floor leather, wallpaper, plywood, plastic, polyvinyl chloride (PVC) board, insulation materials, and indoor artificial board, such as sandwich panels, ash and other glued plywood, MDF furniture and fine art works will release volatile organic compounds. The US Environmental Protection Agency has identified 350 species, mainly aromatic hydrocarbons and aliphatic hydrocarbons. The pollution period of different decoration materials is not the same. Domestically, three commonly used decorative materials such as flooring, paint, and wallpaper were tracked and measured. The study found that the three materials had a pollution period of one month, two months, and three months respectively. Indoor volatile organic compounds can stimulate the skin, mucous membranes and nervous system, resulting in a series of allergic symptoms and neurobehavioural abnormalities. The pathological study found that the tear film stability of the subjects decreased, changes in tear cell composition, increased albumin levels, nasopharyngeal Congestion, there are a lot of inflammatory cells. Animal tests indicate potential mutagenicity, teratogenicity, and carcinogenicity. 2, radionuclides Radionuclides in building materials are mainly radium, radon and uranium. Domestic scholars have reported that the internal and external radiation indices of wall building materials are highest in granite and cinder bricks, and limestone and concrete are relatively low. The level of radioactivity of decorative materials such as marble bricks and tiles is also higher, and the radioactive glaze of tiles is higher than the back. 3, æ°¡ The indoor squats are mainly derived from the foundations, indoor floors and surrounding soil, rocks, building materials, water supply and outdoor air. The United States, Japan, France, Germany, Denmark, Switzerland and other countries all have reports of indoor radon pollution, and ruthenium is the most important radiation source that humans have contacted throughout their lives. 40% of the annual effective dose of natural radiation received by humans comes from Its daughter. A large number of surveys at home and abroad have confirmed that high concentrations of tritium and its daughters can cause lung cancer. According to the statistics of the World Health Organization, delirium has become the second cause of lung cancer after smoking. 4, other Decoration materials will slowly release some other chemicals that are harmful to the human body. For example, natural stones and ceramic products can precipitate fluorides, sulfides, and metal substances such as lead, nickel, chromium, and cobalt. These precipitates can enter the human body through a contaminated diet, contact with the skin, or formation of aerosols. Commonly used paints, coatings, and plastics contain lead. A survey of 1,101 children aged 2 to 6 years old in 11 kindergartens in 11 cities found that blood lead levels of children in the home improvement family were significantly higher, with the paint wall and the home with paved plastic flooring as the most obvious. There are ways to remove indoor decoration pollution 1, simple method Prolonged ventilation (more than three months). Analysis: Applicable to the decoration of the room with light odor, ventilation, and ventilation for a long time. For the rooms with heavy pollution and poor ventilation, it is difficult to achieve the effect of removing odors. Cost: almost zero 2, the traditional method Use tea, pineapple, etc. to fight odors. Analysis: Basically it is a masking effect or a psychological effect at the very least, and it does not achieve the fundamental role of eliminating pollution. low cost 3, plant method Green plants (such as spider plants, aloe vera, etc.) are placed in the living room. Some plants absorb harmful gases. Analysis: There is a certain absorption effect, and there is the effect of beautifying the living room, but the onset time is longer. low cost 4, chemical methods Using the chemical decomposition reaction principle, products such as formaldehyde trapping agents on the market are used to remove offensive odors. This method is applicable to the processing of plates and other materials during the decoration process. Analysis: If used in the decoration process, can fundamentally solve the problem of sustained release of formaldehyde, but the use of the decoration after the decoration is easy to damage the human body and the surface. Cost: relatively high 5, biological methods With excellent microorganisms and active enzymes, formaldehyde, benzene, ammonia, volatile organics and other harmful substances on the surface and subsurface of the object can be degraded by about 90% in a short time. Analysis: Based on the principle of natural ecological degradation, no secondary pollution, can fundamentally eliminate the harmful gases produced by the decoration, and long-term antibacterial smell, no damage to the finish. Cost: relatively high 6, physical methods The adsorption purification principle (such as the general air purification device) is used to adsorb macromolecular gas suspended particles in the air, and the purpose of filtering and purifying air is achieved through forced air circulation. Analysis: long duration of action and energy loss. high cost 7. Closed cover method The closed product is applied to the surface of large core boards, furniture, etc. to form a coating film. Analysis: This method can temporarily mask harmful substances such as formaldehyde. low cost 8. Photocatalyst method Using titanium dioxide photocatalytic effect to remove harmful gases. Analysis: Effective removal of harmful gases such as formaldehyde, benzene and ammonia, strong removal of harmful microorganisms in the room, strong bactericidal effect against various bacteria, strong self-cleaning effect of the coating itself, and long service life. The use of high-grade finishes may cause damage. higher cost Interior decoration pollution is a new type of pollution that has appeared in the decoration of indoor space in recent years as people's living standards have improved. This is mainly due to the unqualified decoration materials and unreasonable design used by people in the interior decoration process. The above is a brief introduction for Xiaobian.

The harm of radionuclides to the human body involves genetics, immunity, hematopoiesis, digestion and many other systems. Radiation also has carcinogenic, mutagenic, and immunosuppressive effects.
