利用气相色谱质量联用仪和高效液相色谱仪分别对长途客车车内空气污染物中的挥发性有机物和甲醛进行分析。定性分析结果表明，长途客车车内空气污染物中烷烃、芳香烃和烯烃分别占41.4%、27.6%和20.7%；定量分析结果表明，对人体有较大危害的甲醛和苯系物在长途客车车内空气污染物中含量较高。随着长途客车停放或运行时间的增加，车内空气污染物浓度有显著的降低。
利用氣相色譜質量聯用儀和高效液相色譜儀分彆對長途客車車內空氣汙染物中的揮髮性有機物和甲醛進行分析。定性分析結果錶明，長途客車車內空氣汙染物中烷烴、芳香烴和烯烴分彆佔41.4%、27.6%和20.7%；定量分析結果錶明，對人體有較大危害的甲醛和苯繫物在長途客車車內空氣汙染物中含量較高。隨著長途客車停放或運行時間的增加，車內空氣汙染物濃度有顯著的降低。

The authors analyse the volatile organic compounds(VOCs)and formaldehyde of air pollutants inside coach respective ly by gas chromatography-mass spectrometry (GC-MS)and high performance liquid chromatography (HPLC). The qualitative analysis results show that the alkanes are found in the air pollutants inside the coach. The aro-matics and olefins respectively are 41.4%,27.6%and 20.7%. The quantitative analysis results show that the formalde-hyde and benzene in the coach air pollutants take up a higher percentage which has a greater hazard to human. With the increment of the coach placing or running time, the concentrations of the air pollutants decrease significantly.
