Recently, there has been a growing public concern over indoor air quality not only in buildings but also in vehicles. Since the vehicle is the main form of daily transportation for most people, of particular concern is the symptoms suffered by both drivers and passengers such as fatigue, headache, and eye stimulation caused by formaldehyde and volatile organic compounds (VOCs) emitted from the interior materials of newly assembled vehicles.
In order to address this problem, leading automobile manufacturers have voluntarily conducted the measurement and management of indoor air quality for new vehicles. Audi and Mercedes Benz use sensory tests carried out by a Nose Team to control the odors in new cars. Furthermore, ISO/WD 16000-26, which specifies automobile interior materials, is currently being included in ISO/TC146 /SC6.
In June 2007, the Korean government also proposed “The standard of indoor air quality new vehicle” and reported the results, which demonstrate that the harmful impact of chemical pollutants might be minimised by indoor air control strategies such as ventilation of the new vehicle within 90 days after it is manufactured. From the results [Ref 6-2], it can be seen that ventilation is as effective within a vehicle as it is in similarly enclosed spaces such as within buildings.
