| 摘 要： | 研究了南京冬季大气气溶胶PM10中PAHs的来源及特征。结果表明,通过特征比值的比较,得出南京冬季PM10中PAHs主要来源于车辆排放;通过后向轨迹法分析看出,除了南京外,因为盛行东北风,南京东北方向的山东地区也是南京冬季PM10中PAHs的重要来源;相关性分析表明,高环数的PAHs间相关性很高,表明它们可能来自相同的污染源;南京冬季PM10中,2环PAHs（Nap）的昼夜变化与其他环数PAHs不同,其质量浓度在夜间总是稍高于白天。

| Abstract: | The main sources and characteristics of PAHs in PM10 during winter in Nanjing are studied.The results indicate that based on the comparison of characteristic ratios method,the main sources of PAHs in PM10 during winter in Nanjing are vehicle emissions;by method of analysis of hysplit,beside Nanjing,Shandong and Shanghai are as the main sources of PAHs in PM10 during winter in Nanjing under northeasterly.Correlation analysis indicates that because of the high correlation,they may come from the same source,and diurnal variation of second ring PAHs(NaP) are different from other rings,the mass concentrations at night are slightly higher than daytime. |
