| 摘 要： | 2013年4月在广州市区对大气中挥发性有机化合物(VOCs)进行了观测,对其变化特征和来源进行了分析。结果表明,观测期间测得的VOC总平均混合比为41.35×10~(-9),表现为烷烃芳香烃烯烃炔烃;利用PMF解析出观测时段内影响广州市区的9个VOCs主要来源,各源占比情况依次为:LPG排放老化VOC汽油挥发石化、未知源汽油车排放油漆溶剂柴油车排放天然源;与机动车相关和工业相关的来源分别占到了大气VOCs的46.8%和21.0%。

| Abstract: | Atmospheric VOCs were measured at Guangzhou in April 2013. The variation pattern and emission sources were ana-lyzed. The average concentration of total VOCs observed was 41. 3 × 10 -9 , which showed a descending order of alkane>aromatic hydrocarbon>alkene>alkyne. Source analysis of VOCs by PMF showed that the LPG emission>aged VOC>gasoline vapor>pet-rochemical industry, unknown source emission>gasoline vehicle emission>solvent use source>diesel vehicle emission>biogenic emission. The sources related to vehicle emission and industrial activities accounted for 46. 8% and 21. 0% of total VOCs respec-tively, it showed control measures to vehicle and industry should be strengthened. |
