Automobile industry has been rapidly developed and pollution it may bring to the environment has been a big concern. For decades, focus has been put on the fuels that autos are using and alternative fuels have been investigated. Researchers have alsoconcerned about materials used in automobiles that may contain detrimental compounds and bring in potential risks to people's health (Elke et al. 1998; Guadarrama et al. 2002). Volatile or semi-volatile toxic substances are more likely to release to either the cabins of cars or straight to the atmosphere. Odors as well as toxic compounds in the cabins of cars and outer layer, may have adverse effects to drivers and passengers, even more, when releasing to the outdoor atmosphere, they will affect more people at a much larger scale. Materials used in cars can fall into varieties of categories of different chemical compounds. As a consequence, to monitor compounds released from automobile materials is a challenge for analytical chemists given that samplematrix can be extremely complicated and level of compounds involved can be very low. Therefore, it requires an analytical method to be both sensitive and as less influenced by the matrix as possible.
