What You'll Learn
Volatile organic compounds (VOCs)
VOCs are commonly found in new cars, where they are released from various manufactured materials such as leather, plastics, textiles, adhesives, and other chemicals. The "new car smell" is caused by these VOCs off-gassing, or releasing harmful chemicals into the air. Some of the VOCs found in new cars include acetaldehyde, benzene, formaldehyde, styrene, toluene, and PFAS. These chemicals can pose health risks to occupants, with potential side effects including headaches, sore throats, nausea, and drowsiness.
To reduce exposure to VOCs in new cars, it is recommended to keep the car well-ventilated by driving with the windows open and parking with the windows cracked. Using a portable air purifier with HEPA filtration and activated carbon filters can also help to remove VOCs and improve air quality. It is also important to wash hands thoroughly after handling car parts, as chemicals can linger on surfaces and be transferred to the skin.
Regulatory agencies are working to reduce and eliminate the use of VOCs in car production to improve air quality and protect human health. The European Union's VOC Solvents Emissions Directive, for example, aims to reduce industrial emissions of VOCs in various solvent-using activities, including vehicle coating and the manufacture of paints and varnishes.

Carcinogens and other toxic chemicals
The "new car smell" is caused by a chemical cocktail emitted from interior parts, including dashboards, seats, carpets, and other components. These parts are made with plastics, adhesives, fabrics, and other materials that release chemicals through a process called off-gassing. While some people find the smell pleasant, it has been linked to various health risks and side effects, including carcinogens and other toxic chemicals.
One of the primary carcinogens associated with the new car smell is benzene, which has been classified as a Group 1 carcinogen ("carcinogenic to humans") by the International Agency for Research on Cancer (IARC). Benzene is a volatile organic compound (VOC) that is emitted from various sources, including vehicle fuels, paints, varnishes, and adhesives. It is essential to keep new cars well-ventilated while driving and to consider purchasing a used car that is at least two years old, as the majority of off-gassing would have already occurred by then.
Another VOC and potential carcinogen found in new cars is formaldehyde. A study by researchers at Harvard University and the Beijing Institute of Technology found that formaldehyde levels in new cars exceeded Chinese national safety standards by 34.9%. Formaldehyde is a colorless, flammable gas with a strong odor, and exposure to it has been linked to an increased risk of cancer. Acetaldehyde, another VOC found in new cars, is also classified as a probable human carcinogen.
In addition to benzene, formaldehyde, and acetaldehyde, other toxic chemicals have been identified in new cars, including toluene and xylene. Toluene is an additive found in vehicle fuels, paints, and adhesives, and it is classified as a reproductive toxicant in the European Union. Xylene is used in the production of plastics, leather, and rubber, and exposure to it may cause liver and kidney damage, as well as neurological issues such as dizziness and headache.
The health risks associated with the new car smell are not limited to carcinogens. A two-year study by the CSIRO in Australia found various health problems, including disorientation, headaches, and irritation in some drivers of new cars. Researchers in another study recommended that new car owners drive with the windows open to reduce exposure to these chemicals. Similar recommendations include parking in the shade with the windows open, using air purifiers, and placing VOC-absorbing materials inside the vehicle.

Health risks and side effects
The "new car smell" is caused by a variety of volatile organic compounds (VOCs) off-gassing from various manufactured materials in a car's interior, such as leather, plastics, adhesives, textiles, and carpets. While some people find the smell pleasant, it can pose several health risks and side effects.
The chemicals responsible for the new car smell have been linked to several health problems. A two-year study by the CSIRO in Australia reported anecdotal accounts of disorientation, headaches, irritation, and nausea in some drivers of new cars. The study measured pollutant levels in new cars that were high enough to cause similar effects within minutes in controlled experiments. These chemicals include the carcinogen benzene, two other possible carcinogens, cyclohexanone and styrene, and other toxic chemicals.
The effects of these chemicals can vary from short-term to long-term health issues. Short-term effects include headaches, sore throats, nausea, and drowsiness. Long-term exposure to these chemicals can lead to more serious health issues, such as cancer, hormonal imbalances, lowered immunity, and developmental effects in children. Per- and polyfluoroalkyl substances (PFAS), commonly used in new cars for their water and stain-repellent properties, are known as "forever chemicals" due to their persistence in the environment and their association with various health issues.
To minimize exposure to these chemicals, it is recommended to buy a used car that is at least two years old, as the majority of off-gassing would have already occurred. Additionally, good ventilation is crucial when driving a new car. Keeping the windows open, especially during the summer, can help reduce the accumulation of harmful chemicals. Parking in the shade and using solar reflectors can also help, as heat causes more VOCs to escape into the air. Air purifiers with HEPA filters and activated carbon filters can also effectively remove VOCs and other pollutants from the car's interior.
It is important to note that the health risks associated with new car smell are not limited to the initial period of ownership. The levels of VOCs can increase during hot summer months, even after several years of ownership. Therefore, maintaining good ventilation and taking proactive measures to reduce exposure to these chemicals is essential for both new and older cars.

Reducing VOC exposure
The "new car smell" is caused by volatile organic compounds (VOCs) emitted as gases from various manufactured materials in a car's interior, such as leather, plastics, textiles, adhesives, paints, lubricants, and cleaning compounds. While some people find the smell pleasant, it can pose health risks due to the presence of toxic chemicals like benzene, formaldehyde, and acetaldehyde.
To reduce exposure to VOCs in new cars, here are some recommended measures:
Ventilation
Keep new cars well-ventilated by driving with the windows open, especially during the summer months. If possible, park your car with the windows slightly open to allow fresh air to circulate. This simple act can help reduce the accumulation of VOCs and other harmful chemicals inside the vehicle.
Air Purification
Use a portable air purifier designed for vehicles. Look for models with HEPA filtration and activated carbon filters to effectively remove particulate matter and address VOCs and odors. Place the purifier securely inside the car and run it continuously while driving to maintain cleaner air.
Strategic Placement of VOC-Absorbing Materials
Place VOC-absorbing materials strategically around your vehicle. These materials can help capture and reduce the concentration of VOCs inside the car.
Hand Hygiene
Prioritize hand washing after every car trip, especially when driving a new vehicle. Wash your hands thoroughly with soap and warm water for at least 20 seconds. This practice removes potentially harmful substances that may have transferred from surfaces like the steering wheel, gear shift, and door handles. Avoid eating, smoking, or touching your face before washing your hands.
Surface Cleaning
Clean the interior surfaces of your car regularly to remove excess chemicals and absorbed VOCs. Use a HEPA vacuum on all surfaces, including seats, carpets, dashboards, and other areas that come into frequent contact with your body.
Purchasing a Used Car
If you are particularly sensitive to toxicants, consider purchasing a used car that is at least two years old. By this time, the majority of off-gassing would have occurred, and the VOC levels will have significantly decreased, providing a healthier driving environment.

The psychology of new car smell
The scent of a new car is a polarising topic, with some people loving and others hating the smell. The new car smell is caused by volatile organic compounds (VOCs) emitted from various manufactured materials, such as leather, plastics, vinyl, textiles, and adhesives. While some people find the smell pleasant, others, particularly in China, associate it with air pollution and view it negatively.
From a psychological perspective, the new car smell can evoke a sense of pride, accomplishment, and freshness. Dawn Goldworm, an expert in creating and dissecting scents, suggests that the smell of anything new often signifies "a sense of pride and accomplishment". The new car smell is often associated with luxury and quality, and for some, it may be a symbol of achievement and success. This positive association with the smell of a new car can influence purchasing decisions, with some people refusing to buy a car unless it has that distinctive scent.
However, the new car smell has also been linked to potential health risks and toxic chemical exposure. Studies have found that the chemicals responsible for the scent, such as formaldehyde, benzene, and styrene, can cause headaches, sore throats, nausea, and allergies. These compounds are considered air pollutants and can pose a danger to human health, especially in the confined space of a car cabin. As a result, regulatory agencies and automobile manufacturers are working to reduce or eliminate the use of VOCs in car production.
To mitigate the potential health risks, it is recommended to keep new cars well-ventilated while driving and to wash hands thoroughly after handling car surfaces. Buying a used car that is at least two years old can also help reduce exposure to VOCs, as the majority of off-gassing would have already occurred by that time. While the new car smell may be appealing to some, it is important to prioritise health and take precautions to minimise the impact of these pollutants.
In summary, the psychology of new car smell involves the emotional and cognitive responses evoked by the scent. While some people associate it with positive feelings of luxury and accomplishment, others view it negatively due to health concerns. The perception of the new car smell varies across cultures, and regulatory agencies and manufacturers are working to address the potential health risks associated with VOC exposure.
