Drivers and friends should be alert to pollution in the car

As the first of the five hazards that endanger human health, air pollution in the car is the most important. In fact, as early as the 1980s and 1990s, there have been many incidents of injuries and deaths caused by air pollution in cars in the United States. In view of this, the United States regards indoor and car pollution as one of the five major hazards to human health, and its negative impact even exceeds that of nuclear radiation!

The air pollution in the semi-trailer mainly consists of two parts. One is the total volatile organic compounds TVOC. TVOC has strong toxicity, irritation, carcinogenicity and special odor. Long-term exposure will affect the skin and mucous membranes of the human body, thereby causing imbalance of the body's immune level, affecting the function of the central nervous system, causing people to experience symptoms such as dizziness, headache, drowsiness, weakness, chest tightness, etc. It may also affect the digestive system, resulting in loss of appetite and nausea In severe cases, it can damage the liver and hematopoietic system. Organizations such as the World Health Organization (WHO) and the National Academy of Sciences/National Research Council (NAS/NRC) have always emphasized that TVOCs are an important class of air pollutants. Compared with nuclear radiation pollution, the harm of TVOC is also huge but easy to be ignored, thus causing great harm unknowingly.

The second is the bacteria in the car. Usually, due to the use of air conditioners, human carrying and other various reasons, various bacteria will breed in the car, such as Staphylococcus aureus, Escherichia coli, mold, Pseudomonas aeruginosa, Streptococcus pneumoniae... These are usually only heard in the hospital The nouns we arrived were actually close at hand, it turned out that they had been lurking in our car. In the case of Pseudomonas aeruginosa, the infection it causes can occur in any part and tissue of the body, often in burns or wounds, in the middle ear, cornea, urethra and respiratory tract. It can also cause endocarditis, gastroenteritis, empyema and even sepsis. And those more harmful Staphylococcus aureus can even cause pericirculatory failure, threatening human life!

Not long ago, the Chinese Academy of Sciences' Research Center for Physical and Chemical Environmental Analysis conducted a survey. In the testing process, the agency selected 50 common models in the market, with mileage ranging from 10,000km to 270,000km, and tested the air quality in their cars, and finally released the authoritative "Domestic Automotive Air Quality Report". . The results show that the health of the air inside the car is extremely unsatisfactory. Among them, the TVOC contained in the air in the car exceeds the standard by an average of 30% compared with the indoor air quality standard; the total number of bacterial colonies exceeds the standard by an average of 77.65% compared with the Grade 1 reference of the indoor environmental quality evaluation standard, and exceeds the standard by an average of 255.30% compared with the Singapore indoor air quality standard. In the long run, human health has been unknowingly suffered incalculable harm.

In the final analysis, no matter TVOC or the breeding of various bacteria, it is inseparable from the "cultivation" of automobile air conditioners. When summer is approaching, the frequency of use of automobile air conditioners has greatly increased, which has also increased the accumulation rate of various harmful substances. Regular professional cleaning and maintenance of car air conditioners will become an indispensable means for us to fight air pollution in cars.

In this regard, 3M, a top 500 company in the world, has given a final product solution, including four products, which are high-efficiency antibacterial deodorant purifiers.
