owner: Anti-pollution children's room decorated in advance Mr. Yuan is a civil servant. The newly-decorated new residence is located in a residential area of ​​Liusha Road, Nanning. It has three bedrooms and two halls with an area of ​​120 square meters and medium decoration. Due to concerns about decoration pollution, he recently applied for a free environmental testing activity organized by the newspaper "Home Weekly". On April 22, the reporter came to Mr. Yuan's new home together with the testing personnel of the Guangxi Analysis and Testing Center. Examination personnel Pan Gong and Huang Gong entered the living room with closed doors and windows for an hour and did not smell a pungent odor. Mr. Yuan said that the two sides of the living room were balconies and floor-to-ceiling windows, with convection from north to south, and the ventilation effect was better. He was more worried about the children's room. "How old are the children?" Mr. Yuan was a little embarrassed about the reporter's question. It turned out that he was not married yet, and only his parents lived with him. The reason why the children's room has been renovated early is because it has reached the marriageable age, considering the need to get married and have children in the future, I thought about it in one step. He said: "Now buy the children's bed in advance, you don't have to worry about pollution when using it." encounter: Giveaway brown mattress is unknown The inspectors collected air samples in the living room, master bedroom, elderly room and children's room, and used the sampling gap to carry out the on-site formaldehyde detector for testing. The results showed that the living room, master bedroom and elderly room had low formaldehyde content. The children's room is small in size, only seven or eight square meters, with only one child bed on the upper and lower floors. Mr. Yuan said that when I bought this bed, I thought it was solid wood, which is more environmentally friendly. However, I felt that the children's room always smelled after staying. I don't know whether it is the smell of solid wood or air pollutants. The testing personnel used a formaldehyde detector for on-site testing. The data showed that the formaldehyde content in the children's room did not exceed the standard. The probe was extended into the drawer of the bed, and the formaldehyde value of the detector was not increased. Mr. Yuan was relieved. At this time, the reporter saw that the upper and lower mattresses of the children's bed were brown mattresses. Upon closer inspection, it was found that the two mattresses not only had no manufacturer, production address, production date and certificate of conformity, but also no trademark. Mr. Yuan said that the mattress was a gift from the seller when buying a frame bed. Because it has not been used, even the outer packaging film is not torn. Detection: The formaldehyde content of palm mattress exceeds the standard In the past tests, cases of excessive formaldehyde content of brown mattresses were more common. The reporter suggested that Mr. Yuan tear the mattress outer packaging film to carry out on-site formaldehyde content testing. The tester extended the probe between the mattress and the packaging film. Soon, the formaldehyde content on the detector began to change from 0.02 mg / m3 to 0.46 mg / m3. Pan Gong shook his head and said, "The mattress can no longer be used." Then, after the formaldehyde detector data was cleared, another brown mattress was tested, and the same scene occurred again. The test results showed that the formaldehyde content of the brown mattress was very high. More than four times the standard value, it is a truly "poisonous" mattress. "Unexpectedly, it turned out that there was a problem with the mattress." Facing the test results, Mr. Yuan was surprised and said that he wanted to throw away the "poison" mattress. Afterwards, Mr. Yuan continued to ask inspectors to inspect mattresses in other rooms. The mattress in the master bedroom is Simmons, a well-known brand, and the bed with mattress cost nearly 10,000 yuan. After on-site testing, the mattresses in the master bedroom and the elderly room had low formaldehyde content and did not exceed the standard. Mr. Yuan sighed: "It's really cheap and not good, so pay more attention to the merchant's gifts." Using inferior glue is the cause of disaster On the morning of April 25, after laboratory analysis, the indoor air test data of Mr. Yuan's house were all released. The four test points sampled (living room, master bedroom, elderly room and children's room), formaldehyde, TVOC, benzene and ammonia All pollutants reached the standard (see attached table). The formaldehyde content of the brown mattress in the children's room exceeds the standard, why the overall air does not exceed the standard? Pan Gong of the Guangxi Analytical Testing and Research Center explained that most of the formaldehyde is present in plates, wood products, and furniture, and it will be slowly released. If the edge sealing technology is not passed or the use of inferior glue, it will cause formaldehyde pollution. In the past two years, it has been found that palm mattresses produced by small manufacturers and workshops on the market generally have a serious formaldehyde content. This is because such palm mattresses are mostly made of synthetic rubber such as unnatural mountain palm materials and urea-formaldehyde glue. In order to reduce costs, most small manufacturers use low-quality, low-quality glue, which will release a large amount of formaldehyde, which will cause harm to the human body after long-term use. The two brown mattresses in Mr. Yuan's house were also wrapped with the entire outer packaging film during the test, which to a certain extent prevented the release of formaldehyde content in the mattress. If the entire outer packaging film is torn open and the mattress is completely exposed to the air, the overall air quality of the children's room may be a different result. Professional advice: mattresses are closely related to human health, so whether you are buying a brown mattress, a spring mattress or a latex mattress, you must buy a big brand that can issue a test report and has a high market awareness.

The formaldehyde value of "three no mattresses" reached 0.46 mg / m3, which was more than 4 times higher than the standard.
The room smelled strange, and Mr. Yuan, a citizen, suspected that the furniture was not environmentally friendly. However, after testing, he found that the formaldehyde content of the furniture did not exceed the standard. The actual pollution source is a brown mattress without a manufacturer, production address and trademark, and the formaldehyde content is more than four times higher than the standard.
