70% of new car interior TVOC exceeds the standard
From the Indoor Environment Monitoring Center of the National Interior Decoration Association, it is learned that indoor air pollution in automobiles is becoming more and more serious. According to GB/T1883-202 (National Indoor Air Quality Standard), the monitoring center carries out five tests on formaldehyde, benzene, toluene, xylene and TVOC for 50 new vehicles that have been in operation for less than half a year. 70% of the concentration of toxic gases in the vehicle exceeds the standard. Among them, the two indicators of formaldehyde and TVOC exceeded the standard.
During the interview, many car owners told reporters that the smell in the car was unbearable. Yan Chao, director of the Indoor Environment Monitoring Center of Qingdao Interior Decoration Association, said that the harmful gas in the car exceeds the standard and the harmfulness of the indoor indoors is more harmful to the human body. Long-term headaches, dizziness, nausea, etc., severe cases may lead to anemia or even cancer; air pollution can also cause drivers to be restless, unable to concentrate, affect driving safety, and cause traffic accidents.
According to Yan Chao, the pollution source in the car mainly comes from the new car body. For example, various materials such as seats, seat covers and floors in the car contain harmful substances such as benzene, formaldehyde, acetone and xylene. The second is from the interior decoration. The third is that the space inside the car is small, the sealing is better, and the harmful substances such as carbon dioxide emitted by the human body are more and more, and it is easy to cause pollution. At present, China has not yet made clear restrictions on the concentration and content of various harmful gases in the car and formulated corresponding standards. It can only be tested with reference to indoor air testing standards. Therefore, the industry is eager to call on the country to introduce corresponding standards as soon as possible to ensure the safe driving of the owners. .
Now in March 2012, our country issued the GBT 27630-2011 Passenger Car Air Quality Assessment Guide, which can be used to test the air requirements of the car.
