| 摘 要： | 采用二次热解吸-气相色谱.质谱法对室内空气进行了定量和定性分析,共检出挥发性有机物245种,包括烷烃、烯烃、芳香类化合物、卤代烃、醇、醛、酮、酯、醚等化合物,住宅类室内空气中挥发性有机化合物浓度平均值明显高于办公类室内这些物质的浓度平均值,对室内空气样品分析中的特例进行了可能的污染源解析,推测室内过量使用液体胶粘剂有可能是引起污染物严重超标的原因之一. |
| 关 键 词： | 室内空气 挥发性有机污染物 二次热解吸 气相色谱-质谱 |

| Abstract: | The quality of indoor air in Beijing was evaluated by two stage thermal desorption/gas chromatography/mass method. 245 kinds of volatile organic compounds including alkane, alkene, aromatic hydrocarbon, halogenated hydrocarbon, alcohol, aldehyde, ketone, and ether were appeared in the investigated rooms. The results showed that concentrations in residence buildings were much higher than concentrations in office buildings. A special cases more than safety limit were analyzed and excess use of liquid adhesive was one of the pollution sources. |
