Decoration pollution is more scary than imagined
Core Tip: Autumn is the season of decoration. After the house has been re-flavored, many residents have been busy moving to their new homes.
For a short time, some people will find that the body is different, some breathing discomfort, skin allergies, dizziness, nausea, cough, etc. These are the disasters caused by indoor decoration pollution.
The artificial board threatens the respiratory paint to destroy the hematopoietic function. A large number of investigation data confirm that indoor pollution caused by a large amount of toxic gases is much more terrible than the gray sky.
Leukemia, formaldehyde, infant deformity.
These shocking words are increasingly associated with “decoration pollution”.
Some experts pointed out that following the “smoke type” and “incorporating tail gas type” pollution, modern people are entering the third pollution period marked by “indoor air pollution”.
For more people, because the previous failure to recognize the decoration pollution may have serious consequences, the damage caused by people is regrettable.
Indoor Environmental Investigation Report of the Centers for Disease Control and Prevention.
More than 10,000 people surveyed live in more than 10 newly built or newly renovated residential and more than 30 high-end hotels, office buildings, conference centers and laboratories.
The results showed that indoor pollution includes more than 50 kinds of chemical, physical, biological, and absorbing substances. Among them, formaldehyde, benzene and alternative organic matter exceeded the standard by 20 to 30 times, and the highest reached 40 times.
Among the respondents, headache, dizziness, fatigue, poor sleep accounted for 30%; skin mucous membrane irritation accounted for 30% -40%; chest tightness, throat problems accounted for 30% -40%; rhinitis accounted for 40%About %. The World Health Organization has announced that 100,000 people worldwide die every year from indoor air pollution, and 35% of them are children.
Is the five major culprits of indoor pollution really “renovation pollution is fiercer than tigers”?
Zhang Jinliang of the Chinese Academy of Environmental Sciences said that the internal indoor air pollution sources mainly come from the following aspects: the pollution caused by the building itself, such as the background background of raw materials caused by certain building materials, and there is waste; interior decoration materials and processes bringPollution, such as plates, chemical fiber carpets, wallpapers, etc., especially low-grade materials, pollution is more serious; pollution caused by furniture and home appliances, such as plate furniture release formaldehyde, fabric sofa spray tape to benzene pollution.
Scientific research shows that the above materials contain more than 300 kinds of volatile organic compounds, of which the most important, the five most harmful: formaldehyde – mainly plate, such as wood-based panels, sandwich panels and adhesives and other building materials.
Long-term exposure can cause cancer of the nose, mouth, nasopharynx, throat, skin and digestive tract; while low-dose contacts can cause chronic respiratory diseases, pregnancy syndrome, etc., and even cause nasopharyngeal cancer.
Benzene — mainly from paints, paints, glues, wallpapers, carpets, synthetic fibers and detergents, solvents, etc.
Benzene has a special aroma, but it is a strong carcinogen. Long-term rehabilitation can damage the human circulatory system and hematopoietic function, leading to leukemia.
氡—The latest research published by the World Health Organization shows that cockroaches have become the second largest cause of lung cancer after smoking.
Professor Zhi Xiuyi, director of the Center for Lung Cancer Clinical Therapy at Capital Medical University, said that cockroach is a natural radioactive gas, colorless and odorless, like “invisible smoke”. Its main hiding place is thin slices and ceramic products such as ceramic tiles and sanitary ware.
The average strontium content per cubic metre of space increased by 100 Baker, and the clinical risk increased by 16%.
In the United States, about 60 people are killed every day, more than the number of people killed by AIDS.
Ammonia – mainly from concrete additives and interior materials.
Ammonia gas is highly degradable, which has a fast effect on the eyes, throat and upper respiratory tract, and is highly irritating.
Short-term inhalation of a large amount of ammonia will cause tears, sore throat, cough, chest tightness, difficulty breathing, dizziness, vomiting, fatigue and so on.
Especially in winter construction, a large amount is present in the antifreeze.
Total volatile organic compounds – the main purpose of furniture, wallpaper and so on.
Can cause immune level disorders, affect the central nervous system function, dizziness, headache, lethargy, chest tightness and other symptoms, may also affect the digestive system, loss of appetite, nausea, etc., severely can damage the liver and hematopoietic system.
Will these five substances really decorate pollution and become “invisible killers”?
According to the maintenance, indoor pollution caused by decoration materials is indeed an important cause of cancer.
Toxic substances in the decoration may be associated with leukemia.
It is best to have a “physical examination” in the new house. In the face of the newly renovated new house, how should we deal with the air odor?
Several experts have given you the following tips.
Wood stone is used together.
Dong Jingsheng, deputy secretary-general of the China Consumers Association, said that when supplementing the decoration design, a single material should not be used too much. It is best to use wood, stone, glass and wrought iron materials.
The artificial board is selected for about 100 yuan.
Wood-based panels are the easiest source of pollution. There is a simple standard when selecting: the wood-based panels of about 100 yuan per piece are relatively safe; the amount of large-core panels in a room of 100 square meters should be controlled within 20 sheets.
Solid wood furniture is the most environmentally friendly.
Solid wood furniture contains the least amount of glue and less pollution; try not to place large or large-sized furniture in small rooms; do not choose the same furniture as floor materials, especially those with laminate flooring and other artificial flooring.Minimize the choice of wood-based panel furniture.
Ventilate for one month.
Large, complex renovation works, preferably ventilated for a month to live.
For simple decoration or renovation, it is necessary to pay attention to opening more windows to allow air to convect, because the ratio of benzene, formaldehyde, ammonia, etc. is larger than that of air, and it can be more indoors. Only air convection can drive them out.
Give a new home a “physical examination.”
Too many people think that there is a pungent taste after the decoration, and there is no pollution.
In fact, this is not the case. In toxic and harmful gases, formaldehyde has a pungent odor, and it is colorless and odorless.
Located in front, it is best to find a qualified authority to conduct indoor air toxicant testing and evaluation.
For office buildings with flexible decoration area, it is best to choose non-toxic and non-polluting building decoration materials and office furniture; the ventilation time is longer than that of ordinary families; it is best to conduct indoor air quality testing before living; some plants have adsorption to plasma, such asIvy, iron tree can absorb benzene and organic matter, spider plant, aloe vera and other absorbable formaldehyde.
