According to relevant data, indoor air pollution is 5 to 10 times that of outdoor air pollution, and nearly 70% of diseases are rooted in indoor air pollution; Due to the deterioration of indoor environment, the incidence of lung cancer in China is increasing at an alarming rate of 26.9% every year. 80% incidence of leukemia is directly related to indoor air pollution. About 265,438+ten thousand children suffer from upper respiratory tract infection due to decoration pollution, which has become an invisible killer and threatens people's health all the time. In fact, the pollution caused by the renovation of indoor new houses has aroused widespread concern through various media propaganda in recent years, but what should be done to really eliminate pollution? Many people have different understandings and practices.
The renovation of the new house is related to the physical and mental health of the family, so you should be extra careful during the whole renovation process.
After the renovation, it is best to ask a professional environmental protection company to carry out air quality testing and purify the air.
Misunderstanding of environmental protection: there is no pollution without obvious smell
The Xiao Li family in the east bought a new house last year. He renovated his new house in March this year. When decorating, Xiao Li personally went to the building materials market, made repeated comparisons of various materials, and specially bought a batch of environmentally friendly materials. After the renovation, Xiao Li opened all the windows of the new house for ventilation. After living in the new house for more than a month, Xiao Li and his wife moved into the new house with their children who had just been born for more than three months. Xiao Li also knew something about the pollution after the renovation of the new house before, but he thought that he used expensive environmental protection materials in the renovation process. After the renovation of the new house, he kept it ventilated for a while, and now he can't smell the obvious smell when he walks into the new house. Xiao Li believes that there will be no decoration pollution, even if there is slight pollution, it will not endanger the health of his family, so the family moved into the new house with confidence.
Environmental misunderstanding 2: the new house will be fine in a few months.
In the interview, Huang Laobo, who lives in Rambo Bay, told reporters that his family has moved into the new house for more than a year, and his family members are in good health, and no diseases caused by decoration pollution have been found. He said that he bought decoration materials to save money at that time, and did not deliberately buy some environmental protection materials, because those materials marked with the word environmental protection are often much more expensive than ordinary materials. He said that some friends around him didn't do pollution control after decorating their new houses, and now they haven't heard of any diseases. Huang Laobo said with a smile, when it comes to pollution, there are many now, such as air pollution around houses and river pollution. I haven't heard that people who live nearby are sick. Don't be too delicate, just leave your new house for a few more months.
Pollution control method 1: release plants to absorb waste gas.
Some people are lucky or turn a blind eye to decoration pollution, while others take various measures to eliminate pollution. A Jun and his wife both work in big companies and are typical white-collar workers. Usually, I pay great attention to the collection of all kinds of information, so I know something about decoration pollution. At the beginning of this year, after a thousand choices, they bought a house in Langqingxuan. After that, it took them two or three months to transform it. After the renovation, A Jun went online to find some ways to control the pollution caused by the renovation of new houses. After comparison, he found that the methods of pollution control by green plants on the Internet are relatively simple and feasible. For example, aloe, chlorophytum, and Huwei orchid can absorb some harmful gases, such as roses and jasmine. It has bactericidal effect, and cactus can purify the air. So, A Jun went to the flower market and bought five or six pots of flowers, and put a pot in each new house. After more than two weeks, A Jun's family moved into a new house.
Pollution control method 2: Tea pineapple deodorizes.
Aunt Ma is the owner of a bookstore. She often hears the topic of decoration pollution at work. This year, Aunt Ma's family bought a new house. After the renovation, Aunt Ma handled the renovation pollution according to some methods she usually heard from others. She bought some tea leaves and pineapples and put them in the newly-made wardrobe and desk, and put a pot of clean water in each room, and poured some vinegar in the clean water to eliminate the odor in the newly-decorated room.
Pollution control method 3: activated carbon can remove pollution.
Mr. Chen, who lives in Haotou, is the department head of a foreign-funded enterprise. He usually pays great attention to the quality of life in his life. He has long known the pollution problem of new house decoration. In order to ensure the health of the whole family, when the new house was renovated last year, Mr. Chen personally went to the building materials market to buy wood to minimize the amount of wood used in the new house. Some granite and marble with radioactive pollution are also discarded as much as possible. After the renovation of the new house, Mr. Chen went to several environmental protection companies in the city for consultation, and finally gave up because he felt that the management cost was a bit high. Later, he heard that activated carbon can control pollution, so he bought some activated carbon and put it in the corner of every room, hoping to eliminate the pollution caused by the renovation of new houses.
Journalist investigation
The public generally does not know enough about pollution.
During the investigation and visit, the reporter found that many people don't know enough about the pollution problem after the renovation of new houses. Among the more than ten newly moved households surveyed by the reporter, only one asked the decoration company to carry out decoration pollution control, and the other nine households moved in after opening the doors and windows of the new house for a period of time. They think that the new house will not taste too much and will not be polluted after being placed for a period of time. In addition, there is a voice that just because the pollution of new house decoration will bring people pain, some sensational, except in some books, no one around has been sick, so the decoration pollution is not as terrible as the book says.
The voice of experts
There are five main types of decoration pollutants.
So, what pollution does the new house decoration have? How can we effectively control pollution? Recently, the reporter visited Mr. Xiao, the head of an environmental protection company in our city. Mr. Xiao's company is an environmental protection company engaged in indoor pollution control in Zhongshan earlier. In the past, it mainly undertook some large-scale industrial wastewater, waste gas and noise control projects. In recent years, more and more people began to pay attention to the pollution caused by home decoration, so they began to set foot in the field of indoor decoration pollution. Over the past two years, more than 200 families in the city have carried out renovation pollution control.
According to reports, the main pollutants causing indoor decoration pollution are radon, formaldehyde, ammonia, benzene and TVCO. Radon mainly comes from building materials and decoration stones, floor tiles and tiles, and natural stones such as granite and marble also contain radioactive pollution. Wood-based panels, adhesives, some chemical fiber carpets, paints and coatings all contain some formaldehyde. Ammonia mainly comes from concrete additives used in building construction, and additives and brighteners used in furniture finishing will cause ammonia pollution. Benzene is mainly volatilized from paint, and natural water, thinner and various adhesives will release a lot of benzene. Indoor TVOC is mainly distributed by building materials, interior decoration materials and daily office supplies. When these indoor pollutants exceed the standard or the human body inhales these pollutants for a long time, it is easy to induce a series of diseases such as lung cancer, nasopharyngeal carcinoma and leukemia.
Single pollution control effect is not good.
Mr. Xiao said that some people think that the materials used in the renovation of new houses meet the national environmental protection standards and there must be no pollution indoors. This is a misunderstanding. In fact, if a large amount of the same material is used in a certain space, the indoor air quality may not meet the requirements due to the cumulative effect. Secondly, some people think that if you can't smell anything, there will be no pollution in the indoor environment, but in toxic and harmful gases, such as radon, it is colorless and tasteless, so it is inaccurate to judge whether there is pollution only by smell. Some people put green plants in new houses to eliminate pollution, but green plants absorb and decompose pollutants slowly and for a long time, and the effect of a small amount of green plants is not obvious. As for the use of tea, pineapple, etc. It didn't play a radical role in pollution, but covered up the unpleasant smell with fragrance. Now some people use air purifiers and activated carbon to eradicate indoor pollution, which can't solve the problem, especially when using activated carbon, when its adsorption reaches a certain saturation level, if it is not replaced in time, it will cause new pollution.
Decoration pollution must be comprehensively detected.
Mr. Xiao pointed out that ventilation must be strengthened during the renovation of new houses to reduce the concentration of pollutants and reduce the harm to the human body. In addition, some auxiliary methods should be adopted, such as using an electric fan to blow the wardrobe to promote the rapid ventilation of furniture and rooms. Turn on the air conditioner as little as possible when you check in to avoid leakage of pollutants. It is understood that there are nearly 10 decoration pollution control companies in Zhongshan, and the cost of new house decoration pollution detection in the market is generally around 300 yuan, a detection point, and the treatment cost is generally 30 yuan money per square meter. If a house of 100 square meter is used, it will cost about 3000 yuan to control pollution.
Professionals remind that it is too late to spend a little money. Don't be lucky about decoration pollution. Over time, it will slowly damage people's health. After the renovation of the new house, it is best to invite qualified environmental protection companies to carry out pollution detection and treatment, especially for families with old people and children. Don't ignore the invisible killer of decoration pollution. Mr. Xiao said that to raise people's awareness of the dangers of decoration pollution, all parties need to work together, especially some formal decoration companies and environmental protection companies should unite to give people active publicity and guidance.

Small knowledge of decoration
1, the decoration must choose a formal and powerful home improvement company. At present, some formal and large-scale decoration companies in the home improvement market are gradually launching new measures of "green decoration" and "environmental protection decoration". They not only incorporated the indoor air quality after renovation into the quality acceptance of the whole renovation project, but also promised to invite the formal indoor environmental testing department to conduct indoor environmental testing after renovation.
Be careful when choosing decorative materials and buying furniture. When buying decoration materials, you must ask the merchants for the test report issued by the authoritative department. When buying furniture, you should sign a contract with the merchant to ensure that the purchased furniture will not pollute the indoor environment. Choose granite, tiles, etc. It's best to ask the testing department for testing before decoration.
Don't rush into the newly renovated house. It is best to stay in after two to three months of ventilation. Families who have already checked in should pay attention to maintaining indoor air circulation.
4. Before the decoration, you should consult the indoor environment experts in order to master some necessary knowledge of environmental protection decoration. Before check-in, we should entrust the indoor environmental inspection department to carry out indoor air testing to ensure that the indoor air is not polluted before check-in.
5. Carefully select indoor environmental testing units. It is necessary to select testing units, testing instruments and testing laboratories recognized by the national metrological supervision department with indoor air quality testing business qualifications for testing.
6. Raise some flowers and plants that absorb harmful substances, such as ivy and cycads, which can absorb benzene, evergreen and daisies can absorb trichloroethylene, and chlorophytum, aloe and cycads can absorb formaldehyde. However, the following flowers should not be placed indoors: orchid, bauhinia, mimosa, rose, lily, cordate telosma, oleander, pine and cypress, hydrangea, tulip and rhododendron.
