The peak area ratio of volatile organic components in China VIB vehicle gasoline sold at a certain gas station was determined using headspace gas chromatography-mass spectrometry.The results show that the volatile organic compounds in China VIB vehicle gasoline are mainly C5-C9 components,in which alkanes are the most abundant,aromatics are the second,and olefins are the least.The peak area ratio of isopentane is the highest in alkanes,fol-lowed by isohexane and trimethylpentane.The peak area ratio of toluene is the highest in aromatic hydro-carbons,followed by xylene.In alkenes,C6 compo-nents are dominant,with 3-methyl-2-pentene having the highest peak area ratio.The peak area ra-tio of volatile organic compounds in China VIB gaso-line can serve as an important basis for identifying hazardous factors of China VIB gasoline and preven-ting VOCs pollution in the air of gas stations.
