基于选择离子色谱图(SICS)的预处理和组合部分的主成分分析(PCA)的化学计量学方法被用来描述Araucaria、Guajuvira、General Lucio和Balsa Nova市(巴西巴拉那州伊瓜库河流域)土壤和沉积物中的碳氢化合物剖面，并指出碳氢化合物污染的主要来源。这项研究在两个单独的分析中包括38个多环芳烃(PAC)和4个石油生物标志物的SIC。受污染最严重的样品位于总统Getulio Vargas炼油厂区域内。这些样品代表了成岩模式和不同的风化程度。来自炼油厂区域以外的样品要么污染较少，要么没有污染，或者含有成岩、热解和成岩输入的混合物，其中不同比例的输入占主导地位。距离工业活动最远的地区(新巴尔萨)的PAC污染水平最低。没有证据表明来自炼油厂区域外的样本与Cusiana泄漏的石油之间存在肯定的匹配。(C)2012爱思唯尔B.V.保留所有权利。
A chemometric method based on principal component analysis (PCA) of pre-processed and combined sections of selected ion chromatograms (SICs) is used to characterise the hydrocarbon profiles in soil and sediment from Araucaria, Guajuvira, General Lucio and Balsa Nova Municipalities (Iguacu River Watershed, Parana, Brazil) and to indicate the main sources of hydrocarbon pollution. The study includes 38 SICs of polycyclic aromatic compounds (PACs) and four of petroleum biomarkers in two separate analyses. The most contaminated samples are inside the Presidente Getulio Vargas Refinery area. These samples represent a petrogenic pattern and different weathering degrees. Samples from outside the refinery area are either less or not contaminated, or contain mixtures of diagenetic, pyrogenic and petrogenic inputs where different proportions predominate. The locations farthest away from industrial activity (Balsa Nova) contains the lowest levels of PAC contamination. There are no evidences to conclude positive matches between the samples from outside the refinery area and the Cusiana spilled oil. (C) 2012 Elsevier B.V. All rights reserved.
