What are the causes of air pollution inside a car?
2 Answers
Sources of air pollution inside a car mainly include the following: 1. The new car itself: The interior of a car is mainly composed of leather, fiber, and various engineering materials, and these materials require the use of harmful substances such as formaldehyde and benzene during production. 2. Car decorations: In the market, car decorations come in various types and materials, with varying quality, and even some 'unbranded' interiors are mixed in. 3. Car air conditioning: For example, when the engine is running, it produces carbon monoxide, gasoline volatiles, nitrogen oxides, etc. 4. Smoking inside the car: If the driver or passengers smoke, it will greatly increase the concentration of pollutants such as volatile organic compounds, carbon monoxide, and dust. 5. Car washing: When washing the car, if cleaning agents or dry cleaning agents are used inside the car and ventilation is not properly managed afterward, it may cause secondary pollution.
As a car owner, I often discuss strange odors in the car with my friends. The most common cause is the release of gases like formaldehyde from plastic seats, carpets, and adhesives when the car is new, which can be pungent and cause headaches or allergies over time. Additionally, poor-quality interior materials continuously emit volatile organic compounds. If the car ages, plastic decomposition makes it easier for harmful substances to accumulate. It's recommended to ventilate the car frequently by opening windows when it's new or using activated carbon adsorbents to help purify the air. Don't forget to regularly clean interior surfaces to prevent dust buildup and secondary pollution. Maintaining a healthy environment inside the car is crucial and can significantly reduce these issues.
