Hazards Lurking Around You Car Air Pollution

Where Does In-Car Pollution Come From?

  Hazardous sources of the car itself
  The car is not a natural product, it is assembled from various metal, plastic, leather and other accessories, and there are some harmful volatiles in these materials, such as plastics, rubber parts, fabrics and leather, paints in the car Paints, adhesives, etc., more or less emit formaldehyde, benzene, toluene and other harmful substances, which are mixed in the air inside the car, which is the main cause of the peculiar smell in the car.
  Love beauty and warm decorations
  Cars are personal belongings and belong to us. We habitually decorate and beautify them to show our personal hobbies and love for them.
  At this time, car interior decorations are usually the main source of secondary pollution. For example, many car owners like to put some plush toys, cushions, plastic carpets, child seats, etc. in the car. If the formaldehyde content of these decorations is high, it will cause air pollution in the car.
  ●Lack of maintenance for the air-conditioning system
  We experience the fun of driving and enjoy the convenience and comfort brought to us by the car. When driving, we often use air conditioners, and if the air conditioning system in the car is not properly maintained and cleaned, a large amount of pollutants will accumulate on the filter elements, air conditioning pipes and evaporators, and harmful substances such as amines, nicotine, and bacteria will be produced. Diffuse in the small space in the car, affecting the air quality in the car.
  ●Pollution inside the car and outside the car The pollutants emitted by
  the automobile exhaust pipe, crankcase, fuel evaporation and other ways will also pollute the air inside the car. The pollutants produced are mainly carbon monoxide, nitrogen oxides, olefins and aromatics, etc. . If the vehicle is not well sealed, pollutants from the external environment can easily enter the vehicle and cause air pollution inside the vehicle. The main pollutants are carbon monoxide, particulate matter, hydrocarbons, etc.
What are the health effects of these hazards

  Usually, the odor inside the car mainly contains harmful substances such as formaldehyde, benzene series, TVOC (total volatile organic compounds). It can cause the following hazards to the human body:
  Mucosa irritation The main hazard of
  formaldehyde is the irritation to the skin and mucous membranes. Formaldehyde is a toxic substance in the plasma, which can combine with proteins. When inhaled at high concentrations, severe respiratory tract irritation, edema, eye irritation, Headache.
  Nervous system
  Benzene derivatives can produce symptoms of the central nervous system, such as decreased coordination and impairment of short-term memory, associated with various neurological effects such as muscle weakness, tremor, and language impairment.
  ●Sensitization: Direct
  skin contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, and inhalation of high concentrations of formaldehyde can induce bronchial asthma.

  ●Carcinogenic effect
  High concentration formaldehyde is also a genotoxic substance. Formaldehyde is also classified as a Group I carcinogen by IARC (International Agency for Research on Cancer) and is associated with lung and nasopharyngeal cancer. Benzene is also a class of carcinogens, and exposure to benzene has been associated with increased rates of leukemia, lymphoma, and blood cancer. Ethylbenzene and styrene are classified by IARC as Group 2b carcinogens (possibly carcinogenic to humans).

  ●Other symptoms
  Headache , dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, poor appetite, heart palpitations, insomnia, weight loss, memory loss, autonomic disorders, etc.; long-term inhalation by pregnant women may lead to fetal malformation and even death; Inhalation can cause sperm deformity and death in men.
  What kind of discomfort will the peculiar smell in the car bring us
  When the drivers and passengers have the following 8 symptoms, they should be alert to whether there is pollution in the car.
  ●Eyes, especially the cornea, nasal mucosa and throat mucosa have irritation symptoms.
  ●Dry mucous membranes such as lips.
  ●Easy to have a headache.
  ● prone to symptoms of respiratory tract infection.
  ●I often feel chest tightness and suffocation.
  ●Frequent dizziness, nausea, and vomiting.
  ●Erythema, urticaria and eczema often occur on the skin, and allergies of unknown cause often occur.
  ●Tired easily.
How to Remove Air Pollution in Your Car

  ●Keep the interior of the car dry and clean. Within half a year of driving a new car, if possible, open more windows to keep the car ventilated, increase the air circulation in the car, accelerate the volatilization of harmful gases, and use the air conditioner as little as possible. This is especially true after prolonged exposure to the sun in summer.
  ●New car owners should remove the plastic packaging in the car in time, otherwise harmful substances such as formaldehyde are not easy to release, and the plastic products themselves may also release harmful substances.
  ●Choose the vehicle interior carefully. Try to avoid using chemicals containing VOCs to clean interior fixtures, dashboards, carpets, windows and flooring. When choosing decorative materials, you should choose products from regular manufacturers. If economic conditions permit, it is best to choose green and environmentally friendly decoration materials. Newly purchased textiles such as seat covers in the car should be washed with clean water before use.
  ●Try to avoid using air fresheners containing chemical ingredients. If you really need it, you must refer to the manufacturer’s instructions for use. When buying perfume in the car, don’t choose low-quality perfume because it is cheap.

  ●Activated carbon packs can be placed to absorb odors. Activated carbon is a commonly used adsorbent with good adsorption properties and can absorb various gaseous pollutants and particles in the air, so as to achieve the purpose of removing odors. What to pay attention to when using activated carbon: activated carbon can only absorb formaldehyde, but cannot remove formaldehyde. Once its adsorption capacity is saturated, it can no longer continue to work. Therefore, putting activated carbon in the car is not once and for all, and it is generally replaced every three months.
  ●Using an air purifier is by far the most effective way to purify air. The principle is also different according to different technologies. At present, there are mainly plasma, negative ion, negative oxygen ion, adsorption and other technologies. Purchase according to your own needs, pay attention to its clean air output ratio when purchasing, the larger the clean air output ratio, the higher the purification efficiency of the purifier.
  ●Car owners can choose professional photocatalyst, ozone machine and other deodorizing equipment to thoroughly disinfect the pollution sources at one time. This method takes a short time and has quick results. Photocatalyst disinfection can maintain the effect for 1 to 2 years at a time, and the maximum can reach 5 years. This is a method that can completely eliminate air pollution in the car. Ozone disinfection is also a commonly used sterilization method. The biggest advantage is that it can quickly kill various bacteria, viruses, microorganisms, etc. that cause diseases in humans and animals without causing secondary pollution.
  ●Regularly clean and care the car air-conditioning system, remove the pollutants accumulated on the surface of the air-conditioning evaporator, replace the air-conditioning filter element, and clean the car air-conditioning pipes.
  ●When using the car air conditioner, the air conditioner should be set to the external circulation mode, and the air inside the car and the air outside the car are exchanged to ensure that fresh air from the outside continuously enters the car and people can breathe fresh air.
  ●If the smell inside the car is too strong or you feel obvious physical discomfort after driving, such as eye irritation, breathing irritation or even dizziness, you should consider going to a department with national certification to test the air quality in the car, and you should find out and remove it as soon as possible source of pollution. The infirm, pregnant women, children and people with allergies should not drive or ride in a new car for a long time under closed conditions.
