The air quality of the same room of the qualified furniture decoration may not meet the standard

Provincial interior decoration and decoration engineering quality supervision and inspection station inspectors inspected the air quality of newly-renovated houses. News reporter Tang Jiying "If it is not a rash on my body, I really don't know what the problem is." Zhang Fang, 35, is The personnel director of an enterprise in Xi'an High-tech Zone, she said that after the new house was renovated, the air quality test report issued by the decoration company showed that the formaldehyde content was qualified, and the furniture and sofas she bought also carried a test certificate. But from the second half of last year, she developed a skin rash.

In January this year, when the unit organized a physical examination, the doctor said that the rash was directly related to the indoor formaldehyde concentration exceeding the standard. According to the inspection of the Shaanxi Interior Decoration Engineering Quality Supervision and Inspection Station: the formaldehyde in Zhang Fang ’s air is seriously exceeded. However, when the indoor furniture was removed and then tested, all the air indicators were qualified.

Last year's 152 test reports 60% of indoor air quality did not meet the standard

According to recent statistics from the Quality Supervision and Inspection Station of Shaanxi Interior Decoration Engineering, in 2010, Shaanxi Province issued a total of 152 "Indoor Ambient Air Test Reports" for sampling, inspection, and commissioned testing, of which more than 60% had poor air quality. Reaching the standard, mostly the indoor formaldehyde content exceeds the standard.

Wu Wenjun, chief inspector of Shaanxi Interior Decoration Engineering Quality Supervision and Inspection Station, said that the main reasons for indoor air quality failure are as follows: one is that the decoration is up to standard, and the air quality is not up to standard after the furniture is put in; the second is that the furniture is up to standard Achieved the standard; third, failed to meet the standard in both aspects; fourth, the standard was achieved in the decoration and furniture inspection, but the air pollution still occurred when it was put together, which is a problem like Ms. Zhang Fang ’s home.

The quality of qualified products placed in a room may not meet the standards

Wu Wenjun said that the wood floors, furniture, sofas, wallpapers, etc. in the home all contain formaldehyde, and it is stipulated that as long as the formaldehyde content reaches the prescribed standard, it will be qualified. When all these things are stacked together, the indoor air quality may not necessarily meet the standards. "For example, if four wooden chairs are placed in the dining room, the air quality may be detected, but if it is placed in the study room, the air quality of the study room may not be met!" Wu Wenjun told reporters that it is like the situation in Ms. Zhang Fang's home. The furniture is qualified and the decoration is qualified, but the furniture Once put into the room, it will fail.

Who should be responsible for air pollution, experts say there is a vacuum in supervision

Wu Wenjun said that after the decoration company completes the decoration, if it issues an air quality test report, it can be handed over smoothly; the building materials dealers also come up with a qualified test standard, which is also a qualified product; but when the two appear together, who is the air quality pollution? Responsibility, who should be responsible in the end, there is a vacuum in the current standard setting, becoming a blind spot for supervision.

Field test: better air in ventilated houses

On March 5, the reporter selected a suite of 38 square meters that was renovated a month ago and moved into furniture; a suite of finely decorated commercial houses of 98 square meters that had been renovated two months ago but had not been moved into furniture; For a one-year-old, 89-square-meter commercial house, please check with Shaanxi Interior Decoration Engineering Quality Supervision and Inspection Station. The results showed that the indoor formaldehyde content of the 38-square-meter apartment house exceeded the standard, and the air quality of the 98-square-meter finely decorated room that had been open for ventilation was qualified. The formaldehyde content of the commercial house that had been in the room for one year was barely qualified.

Expert Tips: Put some activated carbon and flowers after home improvement

Wu Wenjun said that the main source of indoor air pollution is the large amount of interior decoration using plywood, blockboard and other artificial boards, wooden floors and furniture made of artificial boards. Wall coverings, wallpaper, chemical fiber carpets, foam plastics, paints and coatings may also pollute the air. In addition, excessive house decoration and poor ventilation conditions are also important causes of indoor environmental pollution. "Now the best way to solve indoor air pollution is to complete the decoration and furniture to enter the room six months after the stay is safer, it is best to choose a summer or heating season." Wu Wenjun said. The conditional citizens should ventilate as much as possible for a period of time after the decoration, preferably more than 6 months. In addition, you can also put some activated carbon and other strong adsorption items and flowers at home.

For a house with poor ventilation, Wu Wenjun suggests closing the doors and windows of the house for 12 to 24 hours before ventilating, and increasing the indoor temperature, which is conducive to the release of organic substances and toxic gases in the decorative materials as soon as possible, and then the doors and windows Open and maintain convection ventilation to allow toxic gases to flow outdoors as soon as possible.
