摘　要：报告了一年四个季节组合样品中的有机成分分析结果。GC/MS定性分析表明，颗粒物有机物可抽提部分中，可分析识别的主要种类有正构烷烃、脂肪酸、多环芳烃等。其中正构烷烃有明显的奇数碳优先，而脂肪酸有明显的偶数碳优先。GC定量分析正构烷烃的结果和HPLC定量分析多环芳烃的结果均显示，天坛站点的有机物污染浓度大于十三陵站点。污染水平秋冬季高，春夏季低，这种季节变化趋势与有机碳总量相同。

Abstract：Organic analyses were carried out for seasonal collective samples. It was revealed by GC/MS measurements that alkanes, fatty acids and polycyclic aromatic hydrocarbons (PAHs) are of the major classes of organic pollutants as extractable and identifiable compounds. It was observed that alkanes are with preference of odd number carbon species, while fatty acids are with preference of even number carbon species. Both quantitative GC data of alkanes and HPLC data of PAHs indicated that organic pollution level was higher in Temple of Heaven site than that in Ming Tomb site. It was more severe in autumn and winter than in spring and summer. The seasonal variation pattern of alkanes and PAHs were similar to that of total amount of OC.
Keywords：atmospheric aerosols; GC/MS; GC; HPLC; alkanes; PAHs
