New Car Smell May Contain Carcinogenic Substances: California Study Reveals Toxic Compounds in New Vehicles and Explains How the Release of These Elements Occurs Inside the Car.
The famous new car smell is often associated with comfort and well-being, but a study from the University of California, Riverside, warns of the risks of this characteristic fragrance. According to researchers, this odor may contain toxic and carcinogenic chemicals, which can pose a health hazard when inhaled for long periods.
In this article, we explain what these compounds are, how they can affect the body, and what precautions should be taken when buying a new vehicle.
Research Points to Carcinogenic Substances in New Car Smell
The study conducted by researchers Aelakhya Reddam and David C. Volz from the University of California found that the new car smell results from the release of volatile organic compounds (VOCs) present in the interior materials of the vehicle. Among the main ones are:
-
Wax notebook falls into latrine 800 years ago, survives intact in Germany and reveals Latin notes that may expose the routine of a high-status medieval merchant.
-
After more than 11 years orbiting Mars, NASA declared the MAVEN probe lost, which disappeared after passing behind the Red Planet in December, began to spin abnormally, depleted its batteries, and never responded to controllers on Earth again.
-
China creates a capsule with artificial intelligence that scans the stomach in just 8 minutes and can reduce costs by up to R$ 1,400, paving the way for a new era of gastrointestinal diagnostics without tubes, sedation, and discomfort for patients.
-
Scientists simulate nuclear fireball in the laboratory and discover a surprise in the radioactive fallout by observing how cesium, uranium, and cerium change when they remain at high temperatures for a longer time.
- Benzene – A substance found in plastics and adhesives in the car’s interior, known to be carcinogenic.
- Formaldehyde – A chemical compound found in foams, fabrics, and carpets, with irritative and carcinogenic potential.
- Toluene – A chemical product used in solvents, which can cause dizziness and headaches.
- Styrene – Present in plastics and rubbers, it can affect the central nervous system.
- Xylene – Used in the manufacture of upholstery and plastics, it can cause irritations and respiratory difficulties.
The researchers concluded that, when inhaled for more than 20 minutes in an enclosed space, such as inside a new car, these substances can exceed recommended safety levels and increase the risk of health damage.
Exposure Varies According to Vehicle Temperature and Ventilation
In addition to the research from the University of California, the National Confederation of Transport (CNT) and the Brazilian Traffic Medicine Association (Abramet) also warn about the presence of harmful compounds in the new car smell.
According to Dr. Dirceu Rodrigues Alves Júnior, an occupational traffic medicine specialist, these gases are by-products of petroleum derivatives and are primarily released in hot or poorly ventilated environments. In warmer climates, the release of these substances can be even more intense due to the heat, which accelerates the evaporation of the compounds.
Another important factor is the length of exposure. People who spend long periods inside new vehicles may be more vulnerable to the effects of these substances. However, there is no statistical data proving a direct relationship between these gases and specific diseases in drivers and passengers.
How to Reduce the Risks of New Car Smell?
Although the presence of chemical substances in the interiors of new vehicles is inevitable, some measures can reduce exposure and minimize health risks:
- Ventilate the Car Regularly – Keeping the windows open in the first few days after purchasing the vehicle helps dissipate the gases.
- Use the Air Conditioning Properly – Whenever possible, use the air conditioning in ventilation mode to renew the internal air.
- Avoid Leaving the Car Exposed to the Sun – Heat intensifies the release of chemical compounds, so prefer to park the vehicle in shaded areas.
- Use Sunshields on the Dashboard – This practice reduces the heating of the car’s interior and, consequently, the release of vapors.
- Clean the Interior Frequently – Wiping down the upholstery and dashboard with a damp cloth can help remove chemical residues.
- Wait for the Dissipation Period – It is estimated that the volatile compounds present in the new car smell significantly reduce after six months of regular use.
The new car smell, although pleasant for many people, contains volatile chemical compounds that can be harmful to health when inhaled for long periods. Studies indicate that substances like benzene, formaldehyde, and toluene may be present in these vapors, especially in newly manufactured vehicles.
However, the risks can be minimized with simple measures, such as keeping the vehicle ventilated, avoiding sun exposure, and using the air conditioning system correctly. This way, it is possible to enjoy the comfort of a new car with greater safety and well-being.
