The volatile organic compounds source profiles of motor vehicle exhaus t, gasoline vapor and liquid gasoline were determined by averaging the ratios of individual VOC species concentration to the total concentrion of all VOC specie s measured. The gasoline exhaust and diesel exhaust display similar distributions . The alkanes and alkenes below C4 are the most abundant compounds in liquefied petroleum gas exhaust. The compounds below C5 and above C6 are the majo r content in gasoline vapor and liquid gasoline respectively.
