The air in the car refuses to "taste heavy"

For the driver who drives on the road, the exhaust gas emitted by the surrounding vehicles is a kind of pollution, and the air quality inside the vehicle may also become pollution. The problem of excessive levels of formaldehyde, benzene, etc. in the air of automobiles, especially new cars, is very common. The World Health Organization has clearly listed the environmental pollution in cars and high blood pressure and AIDS as one of the top ten threats to human health.

At present, China's first "Guide to the Air Quality Assessment for Passenger Vehicles" has been officially implemented since March 1. The first time the relevant standards for air quality in cars have been issued. Recently, the Hangzhou Municipal Bureau of Industry and Commerce and the Hangzhou Municipal Consumer Protection Committee conducted a sample survey of 30 models sold by 30 automobile dealers in Hangzhou. The monitoring results will be announced before and after the 3-15 Consumer Protection Day.

30 major brands of vehicles for sale were sampled. The air quality sampling survey included 30 car brand dealers such as Changan Mazda, Dongfeng Citroen, Changan Ford, Shanghai GM Chevrolet, Dongfeng Peugeot, Mercedes-Benz, Haima, and Zhongtai for sale. A new car, "The monitoring samples were randomly selected from the new cars to be sold in each 4S shop, not the display cars in the exhibition hall. The vehicles under inspection were stationary at the doors, windows and air inlets one hour before the monitoring." The relevant person in charge of Hangzhou Consumer Protection Committee said.

After the sampling is completed, the monitoring agency analyzes the formaldehyde, benzene and TVOC (referring to the total volatile organic compounds, which are the most serious of the airborne organic pollutants) in the sample. The specific monitoring results will be announced around March 15. For the public, people who care about the air quality problems of the car, especially many car owners, will have a reference. The “Guidelines for Assessment of Air Quality in Passenger Cars,” which began on March 1, stipulate eight common types of benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, and acrolein in the air. The concentration requirement of VOCs in vehicles is applicable to the evaluation of air quality in passenger cars. It is mainly applicable to the sales of new production cars. The vehicles in use can also be used as reference, and the monitoring results can be used to judge each indicator with “national standard”. Qualified or not.

The new national standard for indoor air quality is not mandatory. However, although this “Guideline” has national standards for air quality in vehicles, it is a recommended nature, not a mandatory standard. It is not legally binding and cannot be used in virtually all vehicles. Harmful substances are fundamentally inhibited. At the National “two sessions” that are being held, Li Shufu, chairman of Geely Group, a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), has handed over a “Proposal on Enhancing Air Quality in the Vehicle and Preventing Indoor Environmental Pollution”.

Statistics show that in recent years, disputes and lawsuits caused by air pollution in cars have been increasing. Monitoring data show that the toxic gas in the car exceeds the standards, and the damage to the human body far exceeds the air pollution and PM2.5. Li Shufu's proposal focuses on the current status of air pollution in the vehicle, serious damage to air pollution from consumers, and regulatory measures for air quality in developed countries. It is recommended that relevant national ministries and commissions establish an authoritative air in the passenger car. The quality monitoring and issuing agency, like the China New Vehicle Evaluation Regulations (C-NCAP), regularly sampled and released new car air quality on the market, gave consumers a systematic and objective view of air quality in the car, and speeded up passenger cars. The Guidelines for Internal Air Quality Assessment have changed from the current recommended standards to the national mandatory standards.
