| 摘 要： | 用ＧＣ－ＭＳ定量和半定量分析了ＰＡＨ组分，研究了区大气飘尘中检测出１６种母核ＰＡＨ，ＰＡＨ的质量浓度随功能区和季节的变化而不同，冬季ＰＡＨ质量浓度高于夏季；ＰＡＨ污染程度依次为：化工区〉民居区〉交通区〉郊区。根据荧蒽与芘质量浓度比值判别市区内ＰＡＨ主要来源于燃料的不完全燃烧。 |

| Abstract: | Polycyclic aromatic hydrocarbon (PAH) fractions in airborn particulates were quantitatively and semi quantitatively analyzed by GC MS.16 kinds of parent PAH were detected in airborn particulates.Quantity of PAH is changed with function zones and the seasons,its concentrations in airborn particulates in winter were higher than in summer,and in chemical industry zone>in commercial zone>in traffic zone>in suburb zone.The ratio of fluoramthene to pyrene may indicate that PAH in the area was mainly from uncompleted combustion. |
| Keywords: | PAH pollution source airborn particulates |
