Many domestic and foreign investigations have confirmed that: a large amount of toxic gases caused by indoor pollution, than outside the gray sky is far more terrible. Leukemia, lung cancer, infant deformity...... These shocking words more and more "decoration pollution" together. Some experts pointed out that, following the "soot type" and "motor vehicle exhaust pollution", is entering a modern "indoor air pollution" as a symbol of the third period of pollution.
For many people, because I had no recognized decoration pollution may cause serious consequences, resulting in harm to people too late to regret.
Disease prevention and Control Center indoor environment survey report. Survey of more than 10 thousand people living in new or newly renovated more than and 10 residential and more than and 30 high-end hotels, office buildings, conference centers and laboratories. It was found that indoor pollution, including chemical, physical, biological, radioactive substances of more than four kinds of 50 kinds, of which, formaldehyde, benzene and volatile organic compounds exceeded 20 to 30 times, the highest actually reached 40 times. In the survey, headache, dizziness, fatigue, sleep is not good accounted for 30%; the skin irritation symptoms accounted for 30% - 40%; chest, throat problems accounted for 40% - 30%; rhinitis accounted for about 40%...... WHO announced that 100 thousand people die of asthma as indoor air pollution around the world each year, of which 35% are children.
Five indoor pollution culprit
It really is "decoration pollution is fiercer than tigers? China Science Environmental Research Institute researcher Zhang Jinliang said that the source of indoor air pollution in China mainly from three aspects: the building itself caused by pollution, such as some building materials as the raw materials of radioactive background is higher, and radioactive pollutants in the indoor decoration materials and bring; in the process of pollution, such as sheet, carpet, wallpaper, especially low-grade materials, pollution is more serious; the pollution caused by furniture and home appliances, such as furniture release formaldehyde, sofa spray bring benzene pollution. Scientific research shows that more than 300 kinds of volatile organic compounds in the above materials, the most important and most harmful are 5:
Formaldehyde -- mainly come from the plate, such as plywood, cement and other building materials and sandwich panels. Long term exposure can cause nasal, oral, nasopharyngeal, throat, skin and digestive tract cancer, and low doses of contacts will appear chronic respiratory disease, pregnancy syndrome, and even cause nasopharyngeal cancer.
Benzene -- mainly from paint, paint, adhesive, wallpaper, carpet, synthetic fiber and detergents, solvents etc.. Benzene has a special flavor, but it is a strong carcinogen, long-term inhalation will damage the body's circulatory system and hematopoietic function, resulting in leukemia.
Radon - the latest research published by the WHO indicates that radon has become the second largest cause of lung cancer after smoking. Director of the Capital Medical University cancer treatment center Xiuyi said, radon is a natural radioactive gas, colorless and tasteless, like the "invisible smoke", it is the main place of granite and ceramic tile and sanitary ware ceramic products. With an average of 100 per cubic meter of radon per cubic meter of space, the risk of lung cancer increased by 16%. In the United States, about 60 people are killed every day by radon, more than the number of AIDS deaths.
Ammonia - mainly from concrete additives and interior decoration materials. Ammonia is easily soluble in water, eye, throat, upper respiratory tract and fast effect, strong stimulation. Short term inhalation of ammonia will appear after the tears, sore throat, cough, chest tightness, dyspnea, dizziness, vomiting, fatigue etc.. Especially in winter construction, a large number of existing in antifreeze.
Total volatile organic compounds - mainly from furniture, wallpaper, etc.. Can cause immune imbalance, affecting the central nervous system function, dizziness, headache, drowsiness, chest pain and other symptoms, may also affect the digestive system, decreased appetite, nausea, can be serious when the liver and hematopoietic system injury.
The five substances that make decoration pollution become the "invisible killer"? Xiuyi said, leading to the indoor decoration materials pollution is an important cause of cancer. Toxic substances in the decoration may be associated with leukemia.
New house had better first physical examination"
Well, in the face of the new house just renovated, and in a hurry to stay in how we should deal with the smell of the air a few experts to give you a few strokes.
Wood and stone with the use of. Deputy Secretary General China Consumer Association chairman Dong Jingsheng said, in the selection of decoration design, single material can not be used too much, the best of wood, stone, glass and iron and other materials using collocation.
Artificial board choose 100 yuan or so. Artificial board most likely to become a source of pollution, the choice of a simple standard: 100 yuan per piece of artificial board comparison insurance; 100 square meters of room with a large core board to control the amount of less than 20.
Solid wood furniture is the most environmentally friendly. Solid wood furniture glue containing the least amount of pollution is small; try not to place large volume or a large area of the furniture in the space of small room; do not choose the same ground material and furniture, especially the pavement composite flooring and other man-made floor family, as little as possible to choose man-made board furniture.
Ventilation for a month. Large, complex renovation works, the best ventilation for a month to live. For decoration or renovation simple, must pay more attention to the window, let the air convection, because the proportion of benzene, formaldehyde, ammonia and other pollutants than air, more sink to the bottom of indoor air convection, only to take them out.
To the new house "physical examination". Many people believe that the decoration has a pungent smell of pollution, can not smell the smell that no pollution. In fact, not the case, toxic and harmful gases,
