| 摘 要： | 利用热脱附-气相色谱/质谱法(TD-GC/MS)对家庭轿车、客车和环境空气中挥发性有机物进行定性和定量分析.结果表明,轿车和客车车内空气中挥发性有机物主要为烷烃和芳烃,分别占轿车和客车的车内空气中挥发性有机物的74.00%和71.88%,家庭轿车内空气中含有较多的含氧化合物;环境空气中TVOC浓度较低,分别仅为轿车和客车TVOC的7.95%和12.05%;轿车和客车车内空气中苯浓度较高,分别为环境空气中苯浓度的4.43倍和5.58倍.

| Abstract: | The concentration of volatile organic compounds(VOCs)in cars,buses and ambient air are qualitatively and quantitatively analyzed by means of thermal desorption and gas chromatography-mass spectrometry(TD-GC/MS).The results show that alkanes and aromatics are the main VOCs in vehicles and account for 74.00% and 71.88% of total volatile organic compounds(TVOC)in cars and buses respectively,and there are also more oxygenic compounds in cars.In addition,the concentration of TVOC in ambient air is relatively low... |
