北京市空气中气相与颗粒物上多环芳烃的分析
- DETERMINATION OF POLYNUCLEAR AROMATIC HYDROC-ARBONS IN VAPOR AND PARTICULATE FROM URBAN AREA OF BEIJING
- 摘要：用聚氨基甲酸酯泡沫塑料(PUFP)和玻璃纤维滤膜(GF)组成的采样器,采集空气中的气相和颗粒物上多环芳烃类化合物(PAHs),经提取分离后用反相高压液相色谱-荧光检测器进行分析。对北京市有代表性的六个采样点的室外和室内的空气样品进行了测定;分析了气相和颗粒物上七种PAHs化合物在空气中的百分比率以及各采样点冬季和夏季空气中PAHs的浓度。
- Abstract：Polynuclear aromatic hydrocarbons (PAHs) in both vapor and particu-late phases of the air samples from urban area of Beijing was measured. The PAHs trapped on polyurethane foam plugs and glass fiber filter were extracted and separated for analysis using HPLC coupled with a fluorescence detector. Seven kings of PAHs in in-door and out-door samples from six districts of Beijing area were determined.
