Abstract:

2008年12月10日-30日在佛山收集38个大气非甲烷烃(NMHCs)样品,并进行定量分析.结果表明,佛山市大气NMHCs浓度水平比较高,其中甲苯浓度最高((57.83±49.20)μg·m-3),其次为异戊烷((49.39±37.55)μg·m-3)、乙炔((31.00±17.13)μg·m-3)和丙烷((26.59±9.46)μg·m-3).日变化规律表明机动车尾气排放是大多数NMHCs的主要来源,苯/甲苯比值(0.29±0.23)也表明尾气排放是NMHCs的主要来源,同时其它来源如溶剂挥发对佛山市大气NMHCs的贡献不容忽视.后向轨迹反演显示气团的传输路径对佛山市大气NMHCs浓度有一定的影响.
