“…Data in Table 2 showed that for the majority of samples, the LMW/HMW ratios were relatively low (0.05 -0.23) to support the pyrolytic origin (Soclo et al, 1999). Furthermore, BaP as a marker for some combustion-derived PAHs has been investigated in the past few years (Magi et al, 2002), based on the fact that its level in petroleum is usually negligible. The present finding of a significant correlation between BaP and (~16 PAHs -BaP) (r = 0.97, p < 0.0001; Fig.…”

“…The ration between phenanthrene/anthracene (PHEN/ANT) was applied to differentiate PAHs of pyrogenic sources from PAHs of petrogenic sources (SOCLO; GARRIGUES; EWALD, 2000;MAGI et al, 2002;CHEN, 2011;CHEN et al, 2013). To water, SPM and sediment samples the values of this ratio were lower than 10 ( Figure 6A, C, E), indicating that PAHs samples from MRC may be associated to pyrogenic sources (combustion).…”

“…It was observed that not all sample points, applying FLUT/PYR ratio, had the same results as in the PHEN/ANT ratio, because not all sample points and collected samples show PAHs from pyrogenic sources. Some values were more than one, indicating, according to Magi et al (2002) and Chen and Chen et al (2011), PAHs from petrogenic sources.…”

“…This ratio was already applied in other studies (MAGI et al;2002;ZHANG et al, 2004b;LI et al, 2006). The ratio [FLUOR/(FLUOR+PYR)] was employed to assess if the PAHs were originated from the combustion of petroleum byproducts or from the wood, grass and/or coal burning.…”

Polycyclic aromatic hydrocarbons (PAHs) are considered persistent organic pollutants and can cause serious damage in some organisms, including mutagenic and carcinogenic properties. The aim of this study was to evaluate the PAH concentrations in an urban basin and use diagnostic ratios to possible distinguish sources of contamination. The surface water analysis showed predominance of compounds containing 3 to 4 aromatic rings while in suspended particulate matter and sediment there was a predominance of compounds containing 4, 5 and 6 rings. Although present in low concentrations in the sediment, assessment of toxicity equivalent factor (TEF) showed values higher than 3 ng g -1 pellet to 50% of the samples with values of up to 125.35 ng g -1. The use of diagnostic ratios allowed verifying that the main source of PAHs in these aquatic environments, are pyrogenic sources. Still, the use of such relations should be done with caution, trying to assess possible interference of degradation factors Keywords: Diagnostic ratios; Risk assessment; Polycyclic aromatic hydrocarbons; Environmental contamination.

O objetivo desse estudo foi avaliar as concentrações de HPAs em uma bacia urbanizada e utilizar relações diagnósticas para tentar distinguir fontes de contaminação. A análise de água superficial mostrou um predomínio de compostos de 3 a 4 anéis aromáticos, enquanto que para material particulado suspenso e sedimentos houve uma predominância de compostos com 4, 5 e 6 anéis aromáticos. Apesar de baixas concentrações no sedimento, avaliação de equivalentes de toxicidade mostraram valores superiores a 3 ng g -1 de sedimento para 50% das amostras, com valores de até 125.35 ng g PAHs diagnostic ratios for the distinction of petrogenic and pirogenic sources: applicability in the Upper Iguassu Watershed -Parana, Brazil

Bank surface soil and river sediment samples from the middle reaches of the Huaihe River were analyzed by GC-MS for polycyclic aromatic hydrocarbons (PAHs). The total PAHs concentrations ranged from104 to 947 ng/g in bank soils and from 83 to 2599 ng/g in river sediments. The PAHs levels of the studied samples are relatively higher as compared to those from other world regions, which suggest an enhanced deposition of atmospheric PAHs derived from the emissions of fossil fuel combustion in this area. Possible sources from soil and sediments were diagnosed by the paired PAHs isomer ratios and principal components analysis, and the results indicate that the PAHs in the soils mainly came from coal combustion (74 %) followed by combustion of refined petroleum products (26 %), and in the sediments mainly from pyrogenic sources (89 %) followed by petroleum sources of oil spill emissions (11 %). The PAHs exposure risk assessments show that PAHs in majority of the sediments did not pose threats to the ambient ecosystem. However, the calculated total toxic benzo[a]pyrene (BaP) equivalent of PAHs in soil and sediment indicate that BaP is the most potentially carcinogenic individual PAH.
