“…Sediments with high organic carbon content were characterized with high values of PAHs (Witt, 1995;Yang, 2000). The concentrations of PAHs in the study area exhibited positive correlations with the TOC contents (r ¼ 0.73, r < 0.001), suggesting that TOC was a significant factor controlling PAH distribution in core sediments.…”

“…They are at least one order of magnitude lower than those reported for coastal areas subjected to enhanced urban and/or fluvial inputs such as Saronikos Gulf, Greece (Sklivagou et al, 2008); the coastal area off Barcelona, Spain (Tolosa et al, 1996); the Danube estuary, Black Sea (Readman et al, 2002;Wakeham, 1996); and the coastal area off Alexandria, Egypt (Aboul-Kassim and Simoneit, 1995). Total sedimentary PAH concentrations are also significantly lower than those reported for surface sediments in coastal/estuarine areas in the Mediterranean Sea and worldwide receiving enhanced anthropogenic inputs (e.g., Bouloubassi et al, 2012;Cardellicchio et al, 2007;Lipiatou and Saliot, 1991;Sklivagou et al, 2008;Tolosa et al, 1996;Witt, 1995). They are also lower than concentrations found in deep-sea settings such as the Black Sea (Wakeham, 1996), Cap Ferret Canyon/Atlantic Ocean (OSPAR QRS, 2000) and the Arctic Ocean (Yunker et al, 2011).…”

Abstract. Surface sediments collected from deep basins (1018-4087 m depth) of the eastern Mediterranean Sea (Ionian Sea, southern Aegean Sea and northwestern Levantine Sea) were analyzed for aliphatic and polycyclic aromatic hydrocarbons as tracers of natural and anthropogenic inputs. Concentrations of total aliphatic hydrocarbons, n-alkanes and the unresolved complex mixture (UCM) of aliphatic hydrocarbons varied significantly, ranging from 1.34 to 49.2 µg g −1 , 145 to 4810 ng g −1 and 0.73 to 36.7 µg g −1 , respectively, while concentrations of total polycyclic aromatic hydrocarbons (PAHs) ranged between 11.6 and 223 ng g −1 . Molecular profiles of determined hydrocarbons reflect a mixed contribution from both natural and anthropogenic sources in deep-sea sediments of the eastern Mediterranean Sea, i.e., terrestrial plant waxes, degraded petroleum products, unburned fossil fuels and combustion of grass, wood and coal. Hydrocarbon mixtures display significant variability amongst sub-regions, reflecting differences in the relative importance of inputs from various sources and phase associations/transport pathways of individual hydrocarbons that impact on their overall distribution and fate. Hydrocarbon concentrations correlated significantly with the organic carbon content of sediments, indicating that the latter exerts an important control on their transport and ultimate accumulation in deep basins. Additionally, water masses' circulation characteristics also seem to influence the regional features and distribution patterns of hydrocarbons. Our findings highlight the role of deep basins/canyons as repositories of both natural and anthropogenic chemical species.

“…The predominance of higher molecular mass compounds in the suspended particulate material can generate greater adverse effects in the environment, once these compounds tend to induce carcinogenic, mutagenic and teratogenic responses in some organisms, originating chronic effects (WITT, 1995;CAVALCANTE et al, 2007). Otherwise, compounds containing 3 rings are frequently associated to acute effects.…”

“…Regarding toxicity, compounds with two and three aromatic rings exhibit a significant acute toxicity (PEREIRA NETTO et al, 2000) and compounds with a larger number of aromatic rings present a considerable carcinogenic, mutagenic and teratogenic potential (WITT, 1995;CAVALCANTE et al, 2007;HUSSAIN;BALACHANDRAN;HOQUE, 2015;ZHENG et al, 2016). The PAHs may induce growth inhibition, degradation of the lymphatic system, and interference in hematopoietic functions (ZAGHDEN et al, 2007;RUIZ et al, 2011).…”

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. RESUMOHidrocarbonetos policíclicos aromáticos (HPAs) são poluentes orgânicos considerados persistentes e que podem causar sérios danos em alguns organismos, incluindo propriedades mutagênicas e carcinogênicas. 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
