Cars have become an important space for people's daily lives. The indoor air quality of cars has become a concern for car owners. The relevant agencies such as the Automobile Air Quality Inspection Bureau have provided a series of relevant data. According to national mandatory standards, the amount of formaldehyde released per cubic meter of indoor air should not exceed 0.08 mg per cubic meter of indoor air after one hour of closing doors and windows; if it reaches 0.1-2.0 mg, 50% of normal people can smell the odor; when it reaches 2.0-5.0 mg, the eyes and trachea will be strongly stimulated, and symptoms such as sneezing and coughing will appear; if it exceeds 10 mg, it will be difficult to breathe; if it exceeds 50 mg, it will cause pneumonia, etc Critical illness and even death.
"This is a very pungent taste. At first I thought it was leather, but the car has been driving for more than half a year, and it should be cleared up, but it still feels dizzy when I open the door." .
In fact, most people will feel a sense of taste after buying a new car, but the degree varies, and they don't care about it over time. Professor Tian Dexiang, School of the Environment, Peking University, once served as the chairman of the Automotive Environment Professional Committee of the Federation of Engineering Societies of the Chinese Association of Science and Technology. He has been concerned about environmental issues in automobiles for a long time. He told reporters that after buying a new car, some people pay more attention to opening the window for ventilation, so the impact of pollution in the car is not large, but those who ignore it will be more affected. Surveys have shown that 56.71% of people have experienced dizziness and brain swelling in their new cars, and 15.68% have experienced respiratory allergies. "In a certain sense, the pollution in the car is more serious than the exhaust of the car on the health." Nie Jing, associate professor of the Environmental Pollution and Health Research Institute of the Chinese Academy of Environmental Sciences, believes that the emission of exhaust is in open spaces, but A large number of harmful substances are "trapped" in a narrow confined space, and people stay inside for a longer time, which is a hidden health hazard that cannot be ignored. At present, consumers are complaining that there are many suspected diseases caused by pollution in the car, including psoriasis, liver damage, formaldehyde exposure, aplastic anemia, and acute lymphocytic leukemia.
Since pollution in the car cannot be avoided for the time being, improving self-environmental awareness is the best way to reduce harm. How to reduce the pollution inside the car by yourself, experts suggest the following measures:
Leave the new car for a month or two before driving it. In foreign countries, new cars are usually used for a period of time after they are bought, and most people in China buy the cars as soon as they leave the factory. In fact, within 6 months after the new car leaves the factory, it is the peak period for the release of various toxic gases. Therefore, if conditions permit, it is best to store it for a month or two before reuse.
Remove the plastic packaging as soon as possible. Many people buy a new car and cannot tear off the plastic film on the seat. As everyone knows, some plastic films are also a great source of pollution, and they will make the seat lose its breathability and suffocate toxic gases in the car.
Ventilation is best with four doors wide open. Professor Pan Xiaochuan of the School of Public Health of Peking University reminded that before driving in the morning, it is best to open all four doors and change the air. Tian Dexiang said that the problem of pollution in the car in summer is more serious, one is that harmful substances are more easily released at high temperatures, and the other is that temperature rises will accelerate the proliferation of various microorganisms and germs. You can take advantage of this, let the new car get more sun, and then open the four doors to drive away harmful gases. In addition, new cars in the summer should be less closed windows and less air conditioning. Nie Jing suggested that it is best to turn off the air conditioner one or two kilometers before the destination, and only open the ventilation facilities, which is conducive to drying inside the car and reducing the growth of microorganisms and bacteria; every 6 months of use or 12,000 kilometers After that, it is necessary to replace the air conditioning filter.
Floor glue and film are cheap. Low-quality, cheap floor rubber, floor mats, films, steering wheel covers, seat covers, plush toys, cushions, etc. are all strong bases for harmful gases such as formaldehyde, so the interior decoration of the car should be cheap. Car perfume, air freshener are best not to use, so as not to cause secondary pollution.
