After testing the 85 wooden furniture manufacturing enterprises in the country, the General Administration of Quality Supervision, Inspection and Quarantine found that there are at least 15 kinds of chemical poisons in each enterprise, up to 31 kinds, exceeding the standard; among them, enterprises with excessive benzene accounted for 89.0%, and the highest exceeded the standard by 121.5 times; Enterprises with excessive formaldehyde accounted for 76.9%, with a maximum of 116 times exceeding the standard. Ms. Meng is an ordinary citizen of Yanshi City, Henan Province. She couldnâ€™t think of it. A gas she never knew was â€œhiddenâ€ into her life without knowing it. From the initial cough to the later blood in the sputum, and later to the difficulty of breathing, syncope, Ms. Meng spent the past year in such torture. Not only that, Ms. Meng also told reporters: "This year, people living in a street also began to appear similar symptoms to her: cough, blood stasis, difficulty breathing." The doctor's test results for them are: Tracheal infection or mild pneumonia caused by respiratory infection. Where does the source of infection come from? Ms. Meng found that every time it rains or snows, the symptoms will be alleviated, and the most serious symptom is about 5 pm. At this time, it is the furniture factory that started construction at the end of 2009. . In order to verify her suspicions, Ms. Meng specially found a friend who had worked in the furniture factory. For the first time, she knew such a term - formaldehyde. Ms. Meng learned from this friend that there is a large amount of formaldehyde in the furniture panels and painted paint, and Ms. Mengâ€™s furniture factory next door is just a family workshop. The paint is sprayed outdoors. This causes a large amount of formaldehyde to accumulate in the air. The friend also told reporters: "The health of first-line workers in furniture companies will be seriously affected by high-toxicity of formaldehyde, as well as residents near the factory. If consumers purchase unqualified products, the excess formaldehyde will pass. Respiratory tract, skin, etc. enter the body, causing damage to the nervous system, respiratory system, hematopoietic system, etc., and even cause poisoning or death." At present, formaldehyde has been identified as a carcinogenic and teratogenic substance by the World Health Organization, and is also a potential strong mutant. First, its excessive release will seriously endanger human health. Studies have shown that the formaldehyde contained in the decoration and furniture has a release period of 3 to 15 years. The reporter learned from the Youth League Committee of the Zhejiang Provincial Environmental Protection Department that in the recent free air quality testing activities for citizens, after a 9-year renovation, a citizen still detected that the formaldehyde of the furniture exceeded twice the standard. After testing the 85 wooden furniture manufacturing enterprises in the country, the General Administration of Quality Supervision, Inspection and Quarantine found that there are at least 15 kinds of chemical poisons in each enterprise, up to 31 kinds, exceeding the standard; among them, enterprises with excessive benzene accounted for 89.0%, and the highest exceeded the standard by 121.5 times; Enterprises with excessive formaldehyde accounted for 76.9%, with a maximum of 116 times exceeding the standard. The cost is tricky Xu Guangrong, secretary general of the Shanghai Furniture Industry Association, told the reporter: "The formaldehyde content of furniture exceeds the standard, mainly because in the process of processing, once the formaldehyde content of the sheet, glue and paint cannot be guaranteed, the formaldehyde content of the furniture will be unconsciously In addition, in order to reduce costs, enterprises buy inferior plates. The environmentally friendly materials have low formaldehyde content but high cost. Compared with inferior plates, the difference between each piece ranges from 60 to 100 yuan.â€ According to the reporter, the most common plate furniture Important raw materials such as slabs, particleboards, and MDF are generally made of glue and contain a certain amount of formaldehyde. The plates that meet the national standards are E0, E1, E2, of which E0 is the most environmentally friendly, and the lowest formaldehyde content, of course, the cost is also the highest. At present, according to national regulations, the amount of formaldehyde released from furniture should be less than 0.15mg/m3. Xu Guanrong pointed out: "Sometimes manufacturers purchase more environmentally friendly E0 and E1 plates, but in the process of processing, because of other factors such as glue and paint, formaldehyde will exceed the standard." The Secretary General of the Shanghai Raw Materials Committee should tell reporters: Even if green building materials are used, there is no guarantee that the formaldehyde will be exceeded. Although the company has the material certification standard, if the inspection is not strict in the production process, it cannot be guaranteed to be environmentally friendly.â€ In this regard, the government and enterprises should be considered. Should work together to manage the problem of formaldehyde over-standard from the source. At the same time, Xu Guanrong called on production companies to raise their sense of responsibility and environmental awareness. At the institutional level, Lu Weiguang hopes that the state can unify the equipment and methods of formaldehyde detection, so that the testing equipment and methods of enterprises and cities, cities and cities are consistent, reducing the artificial formaldehyde caused by excessive standards, and truly reassuring consumers.
