With the advent of summer, the rise of room temperature, the release of harmful gases in various building materials and furniture has also increased, and the environmental protection of home improvement has been increased by the public, and complaints about interior decoration pollution have become home. Hot spots discussed with the environmental protection community.
The industry reminds the new owners that the main reason for the pollution in the home improvement room is the home improvement materials. The owners should re-decorate the light decoration. In the case of decoration pollution, as long as the source of pollution is correctly recognized, environmental protection materials should be used as the main decoration to reduce the pile-up; if problems are found in time, the pollution can be effectively controlled and the probability of illness can be reduced.

Old people and children suffer first
"I feel uncomfortable, I always feel chest tightness, and I always cough and sneeze." Aunt Li moved to his son's new home to bring a child, but after living for a week, he found many different places from living in the old house. . Now every weekend, Aunt Li returns to the old house, and the physical and mental state of the whole person will be inexplicably better.
In response to this situation, the reporter consulted Mr. Chen, an expert in the treatment of air pollution in Huizhou City. Mr. Chen said that this situation of Aunt Li is likely to be the decoration pollution of the new house. Aunt Li’s inhalation of harmful gases and the physical reaction are more obvious. Usually, because the body resistance of the elderly and children is weak, and they are looking forward to being at home, they are affected by the pollution of the decoration for a long time, and the body reaction is more obvious.
At present, formaldehyde is a major pollutant in newly renovated homes and has been identified as a type of carcinogen by the World Health Organization. It is believed that there is a causal relationship between formaldehyde and leukemia. The elderly and children are at high risk of indoor environmental pollution. The relationship between formaldehyde pollution and childhood leukemia should attract the attention of the whole society.
The latest statistics show that children between the ages of 0 and 14 are high-risk people with leukemia, and environmental pollution, especially indoor environmental pollution, is an important cause. According to the China Indoor Environment Committee, the indoor environment test results of 6,000 households in the past five years show that the number of newly-married and maternal-infant room tests exceeds 70%, and 90% of families with children's health problems exceed the standard. The National Children's Health Institute found in the history of leukemia children that nearly 90% of children have recently renovated their homes, and many of their children are still luxuriously decorated.
How much harm does formaldehyde have on the human body? Environmental experts warn that there is an odor when the indoor content is 0.1 mg/m3 (PPM); it can cause eye tears when 0.5 PPM; it causes sore throat at 0.6 PPM; Can cause nausea, vomiting, cough, chest tightness, wheezing and even emphysema; when the air reaches 230PPM, it can immediately lead to death. Long-term inhalation of low-dose formaldehyde can cause chronic diseases such as chronic respiratory diseases and conjunctivitis.
Prevention
Market-based home improvement pollution supplies are popular
Recently, the reporter found from the major supermarkets in Huizhou City that in the case of home decoration pollution, there were some professional products on the market that drove out the pollution of home improvement. Some plants with decontamination functions were also welcomed by the public.
"If you are not in a hurry, you can choose this kind of activated carbon bag, put a few directly in the room at home, can absorb the harmful gases in the home decoration. If you are anxious to stay, this powerful repellent is very effective." In the supermarket, a salesman who manages the decoration of pollution supplies introduced that the newly listed repellent, as long as the solvent is placed in the room, the window is closed for three days and three nights, the effect of repelling is obvious, and many new hotels adopt this quick method. In addition to odor.
The reporter found that the price of this powerful deodorant should be nearly 80 yuan per box, and a package of about 15 square meters. According to the general house of 100 square meters, to achieve the desired effect, at least buy 5 boxes. The reporter found that many people in the supermarket site consulted and purchased these deodorants.
In addition, there are more and more organizations specializing in air management in Huizhou. A person in charge of a company specializing in air treatment and fresh air system in Huizhou introduced that the common scientific ventilation method on the market is the fresh air system. The fan installed in the ceiling is connected to a series of exhaust vents through the pipeline, the fan is started, and the polluted air in the room is discharged to the outside through the exhaust vent and the fan, so that a negative pressure is formed in the room, and the outdoor fresh air is installed. The air inlet above the window frame (between the window frame and the wall) enters the room, so that indoor people can breathe high quality fresh air.
Misunderstanding
Using environmentally friendly materials does not mean environmentally friendly home improvement
In order to minimize the harm of decoration pollution, environmentally friendly home improvement is gradually favored by the public. It is understood that green environmental protection decoration is to regulate the various processes of design, materials, construction and other decoration, so that the air quality after renovation meets the national environmental protection value or within the national environmental protection value. The reporter learned that many consumers have a misunderstanding of the understanding that the use of environmentally friendly materials will certainly achieve the effect of environmentally friendly home improvement.
Mr. Zhang, the owner of the Donghu Garden, was immediately married, so he was satisfied with the “green†home improvement propaganda of an interior decoration company, and signed a contract for the renovation of the commercial house with the company. According to the contract, the materials used for the decoration are provided by the company, and the company promises to use the decorative materials as environmentally friendly products. After the completion of the project, Mr. Zhang directed the company to pay the remaining construction funds according to the contract. After being admitted to the new house, Mr. Zhang found that there was a pungent smell in the room, so the relevant agencies were asked to check the indoor air quality. The results show that the indoor air formaldehyde content exceeds the national standard by more than 6 times.
The company believes that the materials used in the decoration process are all environmentally friendly products. If there is a problem, consumers should report it to the manufacturer and have nothing to do with themselves.
According to industry insiders, environmentally-friendly decorative materials only refer to the release of harmful substances within the state, that is to say, there will still be a certain amount of harmful gas emissions. The living space of the living room has a problem of environmental capacity. If the amount of environmentally-friendly materials is too much, it will make it difficult for the chemical agents to evaporate quickly, resulting in pollution superimposition, which will lead to decoration pollution.
Experts say that environmentally friendly home improvement is not just about choosing environmentally friendly materials. It requires comprehensive consideration of design, materials and construction. Most people think that the use of environmentally friendly decorative materials is environmentally friendly decoration. In fact, the two cannot be equal. Since there is no domestic standard for measuring environmentally friendly materials and air quality and environmental protection, that is to say, even if 100% of environmentally friendly materials are used, it is difficult to meet the qualified air quality standards due to the superposition problem.

The industry advocates heavy decoration and light decoration
Although the home improvement pollution is invisible and intangible, it is not insurmountable and incurable. Xiao Xiaobo, general manager of Huizhou Jixiang Decoration Design Co., Ltd. introduced some prevention methods to readers, hoping to minimize decoration pollution.
First of all, we must check the design. According to Miao Xiaobo, family room decoration should be based on practicality and simplicity, focusing on “light decoration and heavy decorationâ€. Over-decoration is likely to lead to “superimposed effect†of pollution. “We have encountered some real-life examples. Some consumers have to lay a layer of blockboard underneath when laying solid wood flooring for new homes. But in fact, once there is quality problem in the lower blockboard, formaldehyde and other toxic and harmful The gas will spread and release through the upper solid wood floor. At that time, regardless of replacement or dismantling, the cost of the consumer will be very high.†Xiao Xiaobo stressed that it is necessary to know how to properly whiten.
Checking the raw materials is the key. The use of less polluting materials in accordance with national standards, such as the purchase and use of specially baked wood products, can effectively reduce the amount of formaldehyde released.
Yan Xiaobo reminded consumers to pay special attention to the environmental protection of accessories in the process of home decoration. Consumers often pay attention to environmental issues in the selection of main materials, and some environmentally friendly materials such as adhesives and waterproofing agents are easily overlooked. Some inferior adhesives contain benzene and harmful substances such as formaldehyde and halogenated hydrocarbons. Although the amount of adhesive used in decoration is small, the pollutants in inferior products may cause harm to human health.
The green plants used to decorate the living environment are a powerful tool for purifying indoor air. Studies have shown that under 24-hour lighting conditions, aloe vera can "kill" 90% of formaldehyde in 1 cubic meter of air. Ivy and agave can "swallow" 70% of benzene. Common rose and rose can absorb sulfur dioxide. .
In addition, special reminder, pregnant women during pregnancy should not contact the decoration, and try not to go to the room being renovated, so as not to cause adverse effects on the fetus; the elderly due to low resistance, do not touch the decoration too much. After the renovation, pay attention to ventilation, and wait until most of the pollutants are released.
sound
At present, some decoration companies confuse the concept of environmentally friendly materials and environmentally friendly home decoration, so that consumers only pay attention to the use of environmentally friendly materials when signing the contract, ignoring whether the indoor air quality after the renovation is up to standard. For the pollution problems that arise after the renovation, the decoration companies mostly adopt an avoidance attitude.
For the pollution problems in the decoration, the relevant person in charge of the Huizhou Decoration Industry Association suggested that consumers should write the pollution problem caused by the decoration to the contract. “The contractual clauses are agreed in advance, and the promised should be written, and the relevant documents should be kept in order to better protect their rights in the future.â€
