The patterns of polynuclear aromatic hydrocarbons (PAH) in sediments were studied by Principal Component Analysis (PCA). Phenanthrene (P), fluoranthene (Fl), pyrene (Py), benzo[a]anthracene (BaA), chrysene (Chr), and benzo[a]pyrene (BaP) were used. Three patterns were found: type P, associated primarily with petroleum hydrocarbons, type Fl, from relatively clean marine sediments, and type Py+BaA+Chr+BaP, from industrialized areas. Aerial fallout appears to be the major source of PAH for the latter. There is a considerable variation in the PAH patterns obtained in different laboratories. PCA is a good tool for the study of PAH patterns.
通过主成分分析（PCA）研究了沉积物中多环芳烃（PAH）的模式。使用了菲（P）、荧蒽（Fl）、芘（Py）、苯并[a]蒽（BaA）、屈（Chr）和苯并[a]芘（BaP）。发现了三种模式：P型，主要与石油烃有关；Fl型，来自相对清洁的海洋沉积物；Py+BaA+Chr+BaP型，来自工业化地区。大气沉降似乎是后者PAH的主要来源。不同实验室获得的PAH模式存在相当大的差异。主成分分析是研究PAH模式的一个很好的工具。
