| 摘 要： | 室内装修材料是引起室内污染的主要污染源,可长期向室内空气释放大量的有害物质,给室内环境造成严重的污染,采集装修过程中以及装修完工的居室内空气样品,用Tenax树脂吸附-热解吸/色谱-质谱法定量测定室内空气中挥发性有机物(TVOCs),分析其浓度特征及其影响因素。结果显示,新装修居室内TVOCs平均浓度要远高于室外对照点,苯系物及含氧化合物为其主要污染物,通风对室内空气质量有明显的改善作用。

| Abstract: | The harmful substances released from interior decoration materials cause severe pollution to the indoor environment. The samples were collected in the house being decorated and after the decoration. The concentrations of volatile organic compounds (TVOCs) were determined by Tenax adsorption-thermal desorption /GC-MS, and the factors influencing the concentrations of TVOCs were analyzed. The result shows that the average concentrations of TVOCs in the new decorated room is much higher than that of the outdoor control spot. The mainly composition of TVOCs were the aromatic hydrocarbons and oxygen compounds. Additionally, ventilation can obviously improve the quality of indoor air. |
