Vehicle air pollution need to be cautious

The tempreture is high, the temperature inside the vehicle parked car in the sun can be as high as four or five degrees Celsius, open the door, you will be surrounded by a wave of hot air, some time ago it was said on the microblogging exposure after the car can be boiled eggs micro-Bo, the recent rise of the automotive air conditioning carcinogenic ", said the car after the exposure will release benzene, produce toxins and carcinogenic to humans. Automotive air conditioning can really cause cancer?
The microblogging Lane "carcinogenic" rumors
Most recent microblogging has been circulating a "car air conditioning carcinogenic", said interior material will release toxic substances benzene, produce toxins and carcinogenic to humans. Microblogging messages issued by the tens of thousands of times forwarded comments soon.
This sensational the microblogging message from friends "Invincible Reiko" long microblogging called "car air conditioning carcinogen - required reading! ! ! . " Microblogging "According to research, the car dashboard, sofa, air filter will release benzene, produce toxins and carcinogens." The microblogging also mentioned: "acceptable level of benzene per square foot for 50 mg. parking indoors and the windows closed, 400-800 mg of Benzene. parked in the outdoor sun temperature exceeds 15.5 ° C, benzene increased to 2000-4000 mg, exceeding 40 times the allowable amount of people just go to the car and the windows closed, you will not be able to avoid excessive inhalation of toxins in quick succession. "
In recent years, the amount of private car ownership is increasing, and coincides with the summer, heavily air-conditioned car. Therefore, this microblogging, the cause of attention, and has made many people panic. Netizen "obviously I 6688", said: "Too scary, home for many years to open the car down, alas, cycling starting next week. The Road Episode - 13 Ink" friends "Niang said:" When I saw these, I do not want to buy a car, buy a equal buy the ticking time bomb. "
Testing Technology Research Institute City Room Environmental Monitoring Station for this specifically to do a test, the test results found the car by exposure benzene content is very small and does not exceed the March 1 "passenger air quality evaluation Directory "by a predetermined amount. The shell network's "rumor grinder" also said, this is a full and there is no scientific evidence to support the rumors.
The carcinogenic said not groundless
Although proven automotive air conditioning carcinogenic rumors, "carcinogenic" says not groundless.
Currently, the production of a car needed, including metal, wood, rubber, plastic, glass and other materials. In the automotive interior part, the most used materials are plastic and leather, which also includes a large quantity of binder. Most of these adhesives contain neoprene, polyurethane and other chemicals, these substances more or less will be harmful to human health, because if the car is a long time in the sun, the car adhesive or plastic contained chemical substances will be due to the reason of the high temperature that comes out, produce, such as benzene, formaldehyde and other harmful substances, which is why a lot of the reasons for the new car will have a relatively strong taste.
Formaldehyde is a destruction of the the biological cell protein protoplasm poison, the World Health Organization confirmed that formaldehyde for teratogenic and carcinogenic substances, is the source of allergy, long-term exposure will lead to mutations.
Testing Technology Research Institute City Room Environmental Monitoring Station test results show that, although the content of benzene exposure after the car is small, but the content of formaldehyde are seriously overweight. The tests results show that the new car sealed formaldehyde content of up to 0.22 mg / m3, driving a car within formaldehyde content of 0.14 mg / m 3. "Passenger air quality assessment under the Guide concentration of formaldehyde shall not exceed 0.10 mg / m3.
Vehicle air pollution need to be cautious
A car air quality researchers said, the interior components of the car because of the different materials will emit different gases. Dashboard, car roof or sofa sponge will release BTEX chemicals, air conditioning duct hang attached will be released, the vehicle fuel combustion exhaust into the car through the small gap, air conditioning will.
Although the automotive air conditioning carcinogenic say "exaggerated and false ingredients, there is no scientific evidence to support the content of benzene or formaldehyde in the air inside the vehicle after the exposure sufficient to cause cancer, but which give the danger alert can not but be vigilant .
Sources said that the car manufacturers used the adhesive had begun to adopt a low toxicity or non-toxic substances to reduce the generation of hazardous substances of the car as much as possible. But how many car manufacturers will stand on the stance of the majority of consumers use this low toxicity or non-toxic substances, and how to do this effect in the end, if they would take other methods to reduce vehicle air pollution problem worthy of our consumption those who wait and see.
In the present case, the car who suggested the vehicle for a long time confined exposure after the public into the car is a good idea to open the window ventilation, such as the release of toxic substances out before air conditioning; same time, in the car, put some activated carbon package can also adsorption of toxic substances.
