    Journal: Mar Pollut Bull; 2018 Feb; 127():478-483. PubMed ID: 29475688.
    Abstract:
    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-1 and 28.4±6.9ngg-1, with a mean value of 14.4±9.3ngg-1. 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.
