In recent years, home improvement environmental protection has gradually attracted the attention of the public, and complaints about indoor decoration pollution have become a hot topic of discussion in the home and environmental protection circles. Industry insiders pointed out that indoor pollution caused by improper decoration materials due to the splendid pursuit of surface decoration is the main reason for affecting the health of the body, especially the increased risk of children suffering from leukemia and upper respiratory tract infections.
As the peak decoration season is coming, the formaldehyde removal products on the market are emerging one after another. Many formaldehyde removal products have exaggerated publicity. Some products may even cause secondary pollution and cause harm to the human body. Industry insiders remind consumers that reducing indoor decoration pollution must start from the source. The most important thing is to strictly control the quality of building materials during home decoration. After the decoration, you can install windows with ventilation devices or fresh air ventilation devices to speed up the pollutants. Sway.
Pollution in home decoration, the child and the elderly suffer first
The new house in Jiangbei was recently renovated. Mr. Zhang was happily planning to move into the new house, but was dissuaded by her colleague Ms. Lin: "Let ’s put it for a few months, wait for the smell of the decoration materials to dissipate, and then move in. Health should be put first. Bit. "Finally, Mr. Zhang followed the advice of his colleagues and regularly opened doors and windows in the new house to ventilate.
In order to take care of her grandson, Aunt Zhao moved to a new house on the south bank of her son's river, but Aunt Zhao started coughing constantly after moving in. Whenever the daughter-in-law is on holiday, she will go back to the old house in the lower corner for a few days. "In the new house, my throat is particularly uncomfortable, and I always cough." Aunt Zhao said that after returning to the old house, the above symptoms basically disappeared. But Sun Zi's task of care is still a top priority, and Aunt Zhao still has to live in his son's new house. The cough intensified in these two days, and Aunt Zhao went to see the doctor. The doctor learned that Aunt Zhao's house had just been renovated, and suggested that she walk outside to breathe fresh air. If conditions permit, she will first move out of the newly renovated house for a period of time.
Yan Xiaobo, general manager of Jixiang Decoration Company, said that although the decoration company uses environmentally friendly materials, the environmentally friendly materials do not contain any formaldehyde, but only low formaldehyde content; young children, pregnant women, the elderly are particularly sensitive to formaldehyde, Aunt Zhao lived in the newly renovated The house will aggravate her respiratory illness.
According to the pediatrician, the rate of birth defects in newborns continues to rise. In addition to family inheritance and viral infections, it also has a lot to do with pollution factors such as interior decoration and long-term exposure to equipment with radiation.
The latest statistics show that children aged 0 to 14 years have become a high-risk population of leukemia, and environmental pollution, especially indoor environmental pollution, is an important cause. According to the statistics of the China Indoor Environment Committee over the past five years, the indoor environment test results of 6,000 households show that over 70% of newly-married and maternal and child room testing families exceed the standard, and 90% of the families with children's health problems exceed the standard. The National Child Health Agency found in a medical history study of leukemia children: Nearly 90% of the children's homes have been recently renovated, and many children's homes are still luxuriously decorated.
How harmful is formaldehyde to the human body? Environmental protection experts remind that when the indoor content is 0.1 mg / cubic meter (PPM), there is an odor; 0.5PPM can irritate the eyes and cause tears; 0.6PPM can cause sore throat; no matter how high the concentration can cause nausea, vomiting, cough, chest tightness Asthma and even emphysema; when the air reaches 230PPM, it can immediately cause death. Long-term inhalation of low-dose formaldehyde can cause chronic diseases such as chronic respiratory diseases and conjunctivitis.
Unqualified building materials are the culprit
"Unqualified building materials are the first cause of decoration pollution." Yan Xiaobo introduced that there are many reasons for decoration pollution, including unqualified building materials, improper decoration methods, and people's awareness of detecting indoor environment has not yet formed. Among them, unqualified building materials are harmful to the human body. The most harmful.
The data shows that there are more than 300 kinds of volatile organic compounds in the air of modern living room, among which more than 20 kinds are easy to cause harm to human body and even cause cancer. Pediatricians said that construction and decorative materials are the main sources of potential indoor air pollution, while painted furniture, paint, and synthetic fiberboard are the main indoor pollutants.
Many owners believe that the use of environmentally friendly building materials can avoid the harm of decoration pollution. In fact, this is a big misunderstanding. The extensive use of environmentally friendly building materials will result in the accumulation of formaldehyde pollution. Environmentally friendly building materials cannot avoid zero formaldehyde. The content of formaldehyde exceeds the standard.
Yan Xiaobo said that even if the floor meets the environmental protection standards, the decoration board will still exceed the standard, which is caused by the superposition effect, "Several such environmental protection materials are indoors, the harmful substances released are superimposed together, formaldehyde, benzene and other harmful substances The amount of release is greatly increased, therefore, even if a single product meets the standard, indoor decoration pollution will still exceed the standard. "
In addition, some citizens consider whether the decorative materials meet the standards and ignore the glue used during the decoration, and the formaldehyde content of these glues is often very high. Sometimes, it is not ruled out that some products that claim to be environmentally friendly have not actually achieved the standard.
Judging the inaccuracy of pollution by smelling
A considerable number of households do not take pollution seriously during decoration, neglect environmental protection, and buy cheap decoration materials. Yan Xiaobo said that after all renovations were completed, environmental monitoring should have been done, but this last link was often omitted. Some households adopted the method of opening windows to "flavor", and some simply stayed directly.
The pediatrician reminds that it is unreliable to judge the pollution beam by smelling. No smell does not mean no pollution. In the poisonous and harmful gas, formaldehyde has a pungent smell, and radon is colorless and tasteless. "This requires professional environmental testing. Harmful to the human body is formaldehyde, benzene, ammonia, radon, etc. If the decoration cannot be well controlled, people will be severely irritated to the respiratory tract after inhaling high concentrations of formaldehyde. "
Yan Xiaobo said that the formaldehyde contained in the decorative materials can sometimes have a volatilization period of more than 7 years. It is recommended to conduct environmental monitoring before moving into a new house, find a professional company that removes formaldehyde, and place some items to remove formaldehyde at home. Increasing the frequency of indoor ventilation and ventilation is also a measure to reduce indoor air pollution. The best daily ventilation time is from 6 am to 11 am. You can grow some flowers and plants indoors, such as aloe, chrysanthemum, cactus, ivy, chrysanthemum, rose, cuckoo, etc. For the best, it is best to release the plants after finishing the air treatment. "
Use products with formaldehyde removal carefully to avoid secondary pollution
200 yuan 20 bags of hardcover activated carbon, which claims to be "adsorbing 92.9% of indoor pollution in 6 hours"; the price of high-end air purifiers exceeds 3000 yuan, and the filtering system is claimed to "effectively remove 99.9% of indoor pollution factors" ... the decoration is now During the peak season, the public's concern about indoor pollution continues to increase, but the reporter visited the market and found that many products other than formaldehyde have exaggerated publicity, and some products may even cause secondary pollution and cause harm to the human body.
Many consumers have not achieved the expected results after using the above purification products, and some have also had side effects. "The home was filled with activated charcoal packs, and the furniture was sprayed with sealant. A purifier was turned on from morning to night. The family still smoked their eyes. After spraying the sealant, I felt more pungent. "Ms. Wu, who is very focused on health, said that because the pollution is too heavy, the whole family lived in a rented house for two months before moving into a new house.
Mr. Li, who works in a public relations company, has doubts about the promotion of formaldehyde removal products. "I went to the home appliance store, and the salesman said that with the air purifier, the new house can be occupied after two or three days. The more they" blow ", the more unreliable I feel."
Chen Zejia, the person in charge of Huizhou Tianying Indoor Environmental Protection Technology Co., Ltd., said that formaldehyde volatilization is a slow and continuous process, and the amount of volatilization changes continuously with the change of air temperature and humidity. "For example, activated carbon requires flowing air to play Adsorption of formaldehyde molecules and dust, etc. If it can remove more than 90% of harmful substances in the air within 6 hours, it is impossible. "
Chen Zejia analyzed that there is a double standard for the data of "99.9% formaldehyde elimination" advertised by air purifiers. The data used by companies for publicity are measured in specific polluted environments such as laboratories, and the actual purification efficiency is much lower.
He reminded consumers that the most effective and safe way to eliminate indoor decoration pollution is ventilation. In addition, “disinfectants†and “blockers†that decompose formaldehyde chemically should be used with caution to avoid secondary pollution.
