Do you know the “new car smell” may be made up of a broad range of VOCs. VOCs are used to manufacture adhesives, plastics, resins and synthetic rubbers. As vehicle interior is normally not ventilated well, the VOC level can be as much as three times greater than in indoor spaces. This is why nowadays people are more concerned about the potentially harmful of VOCs in the interiors of automobiles.


This test aims to determine 8 types of VOCs (Volatile Organic Compound) level in vehicle interiors. After the service, you will receive a test report and our recommendations (related services and products) based on the results.

VOCs (toxic gases) in Vehicle Interiors and Their Effects to Health

It’s known that exposure to certain VOCs has been directly associated with many health problems. The most common allergic reactions resulting from VOC exposure include asthma, allergic skin, headaches, dizziness, fatigue, eye, nose and throat irritation etc.

Prolonged exposure to high level of VOCs can even case more serious health problems like leukemia, lymph cancer, blood cancer lung, nasopharyngeal cancers, chronic diseases and reproductive disorders.

A number of VOCs commonly found in vehicles have been classified as “carcinogenic”, “probably carcinogenic” or “possibly carcinogenic” to humans by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO).

Common VOCs in vehicles include

  1. Benzene and Formaldehyde – Classified as a Group 1 carcinogen by the IARC (“carcinogenic to humans”).
  2. Ethyl benzene and Styrene – Classified as a Group 2B carcinogen by the IARC (“possibly carcinogenic to humans”).
  3. Toluene is classified in the European Union (EU) as a reproductive toxicant.
  4. Xylene may cause liver and kidney damage.
  5. Acetaldehyde – Chronic exposure may cause irritation of the eyes and skin.

Testing device

We adopt RAE® VOC Monitor to perform the VOC tests.
