The individual concentrations, total amount and sources of 16 priority polycyclic aromatic hydrocarbons (PAH) in sediments collected along of the Poxim River, Aracaju, Brazil, were for the first time determined. The ΣPAH ranged between 2.2±1.5ngg and 28.4±6.9ngg, with a mean value of 14.4±9.3ngg. The Pearson correlation test and Principal component analysis (PCA) were used to assess the correlation between the PAH, organic matter and grain size; and to differentiate the sampling stations. Diagnostic ratios presented predominance of pyrogenic sources. Therefore, the PAH quantified showed the influence of anthropogenic activities near of the Poxim River.
首次测定了巴西阿拉卡茹市波西姆河沿岸沉积物中 16 种优先多环芳烃（PAH）的个体浓度、总量和来源。ΣPAH 的范围为 2.2±1.5ng/g 至 28.4±6.9ng/g，平均值为 14.4±9.3ng/g。采用 Pearson 相关检验和主成分分析（PCA）来评估 PAH 与有机质和粒径之间的相关性，并区分采样点。诊断比值表明以热成因来源为主。因此，定量的 PAH 表明了波西姆河附近人为活动的影响。
