In the United States, vehicle pollution has been listed as one of the "top five hazards to human health"; In China, attention to the problem only began in 2004. That year, someone paid the price with their life. "Case of death compensation dispute caused by excessive benzene in Alto car", "Case of child leukemia suspected caused by Chery QQ", "Case of New Beetle formaldehyde exceeding 3 times".

The environmental quality of car interior is worrying

In the six years since then, from China Interior Decoration Association Indoor Air Monitoring Center to Shenzhen Institute of Metrology and Quality Inspection, a number of institutions in order to confirm the existence of pollution inside the car, respectively, at least 50, many thousands of new cars of the car air quality test, each data out are shocking: More than 90% of cars, benzene, xylene, formaldehyde and other toxic and harmful gases seriously exceed the national indoor air quality standards, the highest even exceed the standard of more than 10 times, far more than 37% of the household decoration pollution proportion. Tests in the United States also show levels of harmful substances in cars are five to 10 times higher than those found in homes and offices.

"Toxic cars" do not divide high school and low school

When Life Times reporters asked most of the Chinese agencies that have tested the air quality of cars, none of them were willing to disclose the specific brands and models of the vehicles that failed the test results. Most of them refused, saying it was "inconvenient to disclose". Song guangsheng of director of committee of monitor of vice chairman of association of Chinese interior decoration, indoor environment tells a reporter only, no matter high-grade car or middle and low grade car, different degree ground exists inside the car pollution problem.

The problem of automobile pollution has been taken seriously at home, but it has been alerted abroad. The Center for Ecological Research has tested more than 200 car models, including steering wheels, control panels, armrests and seats, all of which are closely related to passengers. The results showed that among the top 10 most toxic models, 40 percent were Japanese and 30 percent were South Korean, including international brands such as Nissan, Toyota, Suzuki, Hyundai, Subaru and Chevrolet. Before that, South Korean media also disclosed that the relevant departments in South Korea detected benzene and other carcinogens and harmful substances in the test of new cars more than 20 times the standard.

"Twelve locations emit toxic gases"

Tian Dexiang, professor of environmental school of Peking University, used to serve as the chairman of Automobile Environment Committee of China Association for Science and Technology. He has been paying attention to automobile environmental protection for a long time. He told reporters that some people bought a new car, more attention to the window ventilation, so the impact of pollution inside the car is not large, but people who ignore this point will be affected. Surveys show that 56.71% of people have experienced dizziness and swelling in new cars, and 15.68% of people have experienced respiratory allergies. "In a sense, pollution inside cars is more harmful to health than vehicle exhaust." Nie Jing, associate professor of environmental pollution and health research at the Chinese Academy of Environmental Sciences, believes that exhaust emissions are, after all, in the open space, but in the car pollution, a large number of harmful substances are "trapped" in the narrow confined space, and people stay there for a long time, which is a health risk that can not be ignored. At present, consumer complaints, suspected because of the car pollution caused by the disease psoriasis, liver damage, formaldehyde contact reaction, aplastic anemia, acute lymphocytic leukemia and other kinds of.

How many kinds of toxic and harmful gases are hidden in this easily overlooked "new car smell"? A test in the US found up to 100 volatile organic compounds in the car. Chinese consumer association deputy secretary-general Dong Jingsheng told reporters, from the interior of the car sent out, mainly benzene, toluene, xylene, formaldehyde, acetaldehyde, olefins, aromatic hydrocarbons, acetone, etc.; Carbon monoxide, sulfur dioxide, nitrogen oxides, inhalable particles and so on enter the car from the outside, among which, a considerable part are carcinogens and cause serious harm to the liver, kidney, respiratory system, hematopoietic organs, immune function and so on.

So many harmful gases, exactly from which parts are emitted? Test results show that they are mainly: car seat, instrument panel plastic parts, glue, carpet, ceiling, car seat cover, steering wheel cover, paint, adhesive, car air conditioning, car perfume 11 parts. In addition, there have been calls recently that many domestic cars are used in the asphalt damping plate, containing polycyclic aromatic hydrocarbons and other high carcinogens, has been eliminated by some western countries.
