Decoration not only makes the room comfortable and beautiful, but also pollutes the indoor environment. The World Health Organization calls a series of human damage symptoms caused by indoor pollution "bad building syndrome"

indoor decoration pollution is a new environmental pollution. In short, indoor decoration pollution refers to the pollution of indoor environment caused by decoration behavior. The following editor will teach you a few tricks to keep you away from the trouble of indoor decoration pollution

indoor decoration pollution sources

1. Volatile organic compounds

commonly used decoration materials, such as paint, coating, floor leather, wallpaper, plywood, plastic, polyvinyl chloride (PVC) like board, thermal insulation materials, as well as indoor man-made boards, such as sandwich board, Manchurian ash and other glued veneers, furniture and art works of density board, 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 decorative materials is also different. The three commonly used decorative materials, floor, paint and wallpaper, were tracked and measured in China. The study found that the pollution periods of these three materials were 1 month, 2 months and 3 months respectively

indoor volatile organic compounds can stimulate the skin, mucosa and nervous system, produce a series of allergic symptoms and neurobehavioral abnormalities. Pathological studies found that the stability of tear film decreased, the composition of tear cells changed, the content of albumin increased, the nasopharynx congested, and there were a large number of inflammatory cells. Animal experiments show that it has potential mutagenicity, teratogenicity and carcinogenicity

2. Radionuclides

radionuclides in building materials are mainly radium, thorium and uranium. Domestic scholars reported that the internal and external exposure index of wall building materials is the highest in granite and cinder bricks, while limestone and concrete are low. The radioactive level of decoration building materials such as marble bricks and ceramic tiles is also high, and the radioactive glaze of ceramic tiles is higher than that of the back

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

3. Radon

indoor radon mainly comes from room foundation, indoor ground and surrounding soil, rocks, building materials, water supply and outdoor air. The United States, Japan, France, Germany, Denmark, Switzerland and other countries have reported indoor radon pollution. Radon is the main source of radiation that people are exposed to throughout their lives. 40% of the annual effective dose of natural radiation that people receive comes from radon and its daughters. A large number of investigations at home and abroad have confirmed that high concentrations of radon and its daughters can cause lung cancer. According to the statistics of the World Health Organization, radon has become the second cause of lung cancer after smoking

4. Other decoration materials will slowly release some other chemicals harmful to human body. For example, natural stone and ceramic products can precipitate fluoride, sulfide, lead, nickel, chromium, cobalt and other metal substances, which can enter the human body by polluting diet, contacting skin or forming aerosols. Commonly used paints, coatings, plastics, etc. contain lead. A survey of 1101 2-6-year-old children in 11 municipal nurseries and kindergartens in China found that the blood lead level of children in decorated families increased significantly, especially those with painted walls and plastic floors

there are methods to remove indoor decoration pollution

1. Simple methods

long-term ventilation (more than three months)

analysis: it is applicable to the decorated room with light odor, good ventilation conditions and long-term ventilation. For rooms with heavy pollution and poor ventilation conditions, it is difficult to achieve the effect of removing odor

cost: almost zero

2. Traditional methods

use tea, pineapple, etc. to fight against peculiar smell

analysis: basically, it plays a covering role or a psychological role at all, which cannot fundamentally eliminate pollution

cost: low

3. Plant methods

place green plants (such as Chlorophytum comosum, aloe, etc.) in the room, and some plants can absorb harmful gases

analysis: it has a certain absorption effect, and has the effect of beautifying the room, but it takes a long time to take effect

cost: low

4. Chemical method

uses the principle of chemical decomposition reaction, and uses products such as formaldehyde capture agents on the market to remove odor. This method is applicable to the treatment of materials such as plates in the process of decoration

analysis: if used in the decoration process, it can fundamentally solve the problem of continuous formaldehyde release, but it is easy to cause damage to human body and object surface after decoration

cost: relatively high

5. Biological methods

through excellent microorganisms and active enzymes, it can degrade about 90% of formaldehyde, benzene, ammonia, volatile organic compounds and other harmful substances on the surface and sub surface of articles in a short time

analysis: Based on the principle of natural ecological degradation, there is no secondary pollution, which can fundamentally eliminate the harmful gas generated by decoration, and long-term bacteriostasis and odor elimination, without damage to the finish

cost: relatively high

6. Physical methods

use the adsorption and purification principle (such as general air purification devices) to adsorb macromolecular gas suspended particles in the air, and achieve the purpose of filtering and purifying the air through forced air circulation

analysis: the action time is long and there is energy loss

cost: high

7. Closed cover method

paint closed products on the surface of large core boards, furniture, etc., forming a layer of coating

analysis: this method can temporarily cover up harmful substances such as formaldehyde

cost: low

8. Photocatalyst method

uses the photocatalytic effect of titanium dioxide to remove harmful gases

analysis: it can effectively remove formaldehyde, benzene, ammonia and other harmful gases, has a strong removal effect on indoor harmful microorganisms, and has a strong sterilization effect on a variety of bacteria. The paint itself has a strong self-cleaning effect and a long service life, but it may cause damage to high-end finishes in use

cost: higher

indoor decoration pollution is a new kind of pollution in the process of decoration of indoor space with the improvement of people's living standards in recent years, mainly due to the use of unqualified decoration materials and unreasonable design in the process of indoor decoration
