What Causes in-Car Air Pollution?

Pollutants inside a car

Whether you have a new car or an old one, there is always a type of smell in the car cabin. What you smell in your car are volatile organic compounds (VOCs), which cause the weird greasy fog inside the windshield. Your car cabin may have a mix of more than 100 chemicals such as poisonous benzene or formaldehyde.

VOCs are one of the main indoor air pollutants that lead to many health problems. VOCs in your car cabin is present in the car foam in the seats, carpets, dashboard, or glue used in the car to keep the things in place. Apart from VOCs, particulate matter released from the car brakes and aromatic hydrocarbons from various interior components can lead to a number of health problems. Lingering smells of cigarette smoke and other sources also lead to in-car air pollution.

Some of the common sources of air pollution in your car are:

  • Odors
  • Pet dander
  • Carbon dioxide
  • Cigarette smoke
  • Exhaust fumes of car
  • Dust, mold, pollen, and bacteria

Why is Air Pollution Inside Car More Dangerous Than Outside?

Pollution inside a car cabin is high as they take in emissions from the surroundings and recirculate them in the car cabin. In fact, half the pollutants inside the cars come from vehicles that are immediately ahead. Levels of some air pollutants and toxic compounds are almost ten times higher inside the vehicles and the overall air quality is fifteen times worse. Air vents and other openings in the car provide an easy way for the pollutants to enter the car cabin.  According to the Atmospheric Environment, air pollutants are higher at traffic intersections in both urban and suburban areas. Some of the findings include:

  • Stopping at red lights increases air pollution exposure
  • Traffic signals have approximately 29 times higher concentration of particulate matter as compared to open roads
  • Passing through intersections accounted for 25 percent of pollution exposure

Air pollution is quite high at intersections as drivers tend to accelerate, decelerate and idle their vehicles.

How Does it Affect Children?

As children generally sit in the back seat of the car, they are more vulnerable to the harmful effects of in-car air pollution. The fans of the car suck in the exhaust or fumes that come out from a lorry or car behind you. This affects the under-developed lungs of children and they are exposed to the increased risk of sensitization leading to asthma and breathing problems. According to a study in Barcelona, car air pollution also reduces the ability of children to concentrate and also slows down their reaction time.

How Bad is In-car Air Pollution?

Studies have found that the quality in your car cabin can be 5 times worse than the air in your home or office. In-car air pollution can lead to a number of health problems. If you experience headaches, nausea, or sore throat every time you use your car, it is a symptom of in-car air pollution. Constant exposure to in-car air can also lead to cancer and disorders in the immune system. In addition, the place where you live also increases the impact of in-car air pollution on your health. In some cases, children may also become vulnerable to DNA damage because of in-car air pollution.
