Volatile organic compounds (VOCs) are emitted from plastics, vinyl, adhesives, and paints
The "new car smell" is caused by a combination of Volatile Organic Compounds (VOCs) emitted from plastics, vinyl, adhesives, paints, and other materials. These VOCs are a type of air pollutant that can be harmful to human health, even leading to severe impacts such as birth defects and learning disabilities. The compounds are released into the air through a process called off-gassing, which is accelerated by heat. As a result, it is recommended to keep new cars well-ventilated, especially during the summer months when off-gassing rates are highest.
VOCs are aromatic molecules that can be inhaled, ingested, or absorbed through the skin. They are emitted from various manufactured materials used in car interiors, including plastics, vinyl, adhesives, paints, textiles, leather, carpeting, and other components such as the steering wheel, seats, and dashboard. The specific VOCs present in a car's interior can vary depending on the materials used, with some chemicals being more toxic than others.
The potential health risks associated with new car smell have raised concerns among consumers and regulatory agencies worldwide. Studies have found over 50 different VOCs in new cars, with levels reaching up to 7,500 micrograms per cubic meter. These chemicals can cause short-term side effects such as headaches, sore throats, nausea, and drowsiness, as well as potential long-term health issues. To minimize exposure, it is recommended to increase ventilation, use air purifiers or filters, and avoid parking in direct sunlight to reduce the off-gassing process.
Some car manufacturers have started to address these concerns by creating vehicles with improved interior air quality. For example, Toyota has switched to water-based alternatives instead of solvent-based glues, and Ford has adopted soy-based foam instead of petroleum to reduce VOCs. These changes not only reduce potential health risks but also respond to consumer preferences, as seen in the Chinese market, where air quality is a key consideration for car shoppers.
While the new car smell may be appealing to some, it is important to prioritize interior air quality and take steps to reduce exposure to VOCs and other toxic chemicals. Proper ventilation, filtration, and awareness of the potential health risks can help create a healthier driving environment.

Formaldehyde, toluene, benzene, and other chemicals are linked to cancer
The "new car smell" is an appealing scent for many, but it is composed of several toxic chemicals, including formaldehyde, toluene, and benzene, which are linked to cancer. These chemicals are emitted as gases from various manufactured materials in the car's interior, such as leather, plastics, and textiles. While the health effects of these chemicals are a cause for concern, the good news is that their concentrations tend to decrease over time, as observed in a 2005 study.
Formaldehyde, a colorless gas with a strong odor, is commonly used in building materials and household products. Inhalation or skin absorption are the primary routes of exposure, and studies have linked it to cancer, particularly leukemia and nasopharyngeal cancer. Research has shown that exposure to formaldehyde can cause cancer in lab animals, and workers in industries that produce formaldehyde or formaldehyde-containing products may be at higher risk.
Toluene, another chemical found in new car smell, has been associated with an increased risk of thyroid cancer. People living near roads or industrial areas may have higher blood toluene concentrations, which could contribute to the development of thyroid cancer. Vehicle emissions are a significant source of toluene exposure, and the Japanese health ministry has set limits on volatile organic chemicals to address the health concerns associated with new car smell.
Benzene, a colorless liquid with a sweet odor, is used in the production of various chemicals and products, including plastics, resins, and lubricants. Exposure to benzene has been linked to a higher risk of leukemia, particularly acute myeloid leukemia (AML), and other blood-related cancers. Studies have shown that benzene exposure can cause chromosome changes in bone marrow cells, which is where new blood cells are produced.
In conclusion, formaldehyde, toluene, and benzene, which are present in new car smell, are indeed linked to cancer. The potential toxicity of these chemicals is a valid concern, and it is recommended to keep new cars well-ventilated, especially during the initial months after purchase, to reduce exposure to these volatile organic compounds.

Ventilation and air filtration can reduce the impact of air pollutants
The "new car smell" is caused by gases emitted from various manufactured materials, such as leather, plastics, textiles, and other chemicals. A 1995 analysis of the air from a new Lincoln Continental found over 50 volatile organic compounds (VOCs), which were identified as coming from sources such as cleaning and lubricating compounds, paint, carpeting, leather and vinyl treatments, latex glue, and gasoline and exhaust fumes.
The potential toxicity of these compounds poses a danger to human health, with side effects including headaches, sore throats, nausea, and drowsiness. To reduce the impact of these air pollutants, proper ventilation and air filtration are essential.
Ventilation helps to improve indoor air quality by controlling indoor humidity and reducing airborne contaminants, which can contribute to or act as health hazards. Opening windows or using fans can increase ventilation and bring in fresh air, allowing VOCs and other pollutants to exit the vehicle more easily. However, in some cases, outdoor air can also bring pollution indoors, such as diesel emissions from nearby freeways or pollution from factories. Therefore, it is important to pair ventilation with other measures to effectively reduce indoor air pollution.
Air filtration is another powerful tool to reduce the impact of air pollutants. Air cleaning filters are designed to remove pollutants from indoor air, including dirt, dust, debris, pollen, and other allergens. Different types of air filters, such as mechanical, electronic, hybrid, and gas phase filters, can be installed in the ductwork of a facility's central HVAC system or used as portable room air cleaners. Upgrading your car's cabin air filters and regularly changing them can help maintain the product's effectiveness in reducing pollutants.
Additionally, air purification technologies can be utilized to optimize indoor air quality. For example, electrostatic air filters have been shown to substantially decrease indoor PM2.5 levels, leading to improved cardiorespiratory health. HEPA filters or filters with carbon can also offer better protection from pollutants in your car.
In summary, ventilation and air filtration work hand in hand to reduce the impact of air pollutants, especially those associated with the "new car smell." By diluting indoor pollutants, controlling humidity, and removing harmful particles, ventilation and filtration techniques can significantly improve indoor air quality and mitigate potential health risks.
