“…Moreover, PAH levels in the digestive gland were below the levels detected in mussels from Galician waters 2-3 months after the Prestige oil spill or in mussels from some "hot spots" such as the Galician Rias (concentrations of total PAHs above 500 μg/kg dry weight) (Soriano et al, 2006). In comparison to other cephalopod species the total PAH concentrations found in the digestive gland are overall higher than in the whole body of squids (Gomes et al, 2013) and deep-sea squids (over 1000 m depth) from the western Atlantic Ocean (Unger et al, 2008), nevertheless these differences are not higher than 3 folds.…”

“…Naphthalene was the most abundant PAH in the octopus digestive gland in the different sampling periods. Many monitoring studies concerning PAH pollution do not quantify this 2-ring compound (Frias et al, 2010;Lima et al, 2008;Perugini et al, 2007;Santos et al, 2010;Soclo et al, 2000;Soriano et al, 2006) even though it is considered a possible carcinogenic to humans according to IARC (IARC, 2010).…”

Among organic pollutants existing in coastal areas, polycyclic aromatic hydrocarbons (PAHs) are of great concern due to their ubiquity and carcinogenic potential. The aim of this study was to evaluate the seasonal patterns of PAHs in the digestive gland and arm of the common octopus (Octopus vulgaris) from the Northwest Atlantic Portuguese coast. In the different seasons, 18 PAHs were determined and the detoxification capacity of the spe-cies was evaluated. Ethoxyresorufin O-deethylase (EROD) and ethoxycoumarin O-deethylase (ECOD) activities were measured to assess phase I biotransformation capacity. Individual PAH ratios were used for major source (pyrolytic/petrogenic) analysis. Risks for human consumption were determined by the total toxicity equivalence approach. Generally, low levels of PAHs were detected in the digestive gland and in the arm of octopus, with a predominance of low molecular over high molecular weight compounds. PAHs exhibited seasonality in the con-centrations detected and in their main emission sources. In the digestive gland, the highest total PAH levels were observed in autumn possibly related to fat availability in the ecosystem and food intake. The lack of PAH elimina-tion observed in the digestive gland after captivity could be possibly associated to a low biotransformation capac-ity, consistent with the negligible/undetected levels of EROD and ECOD activity in the different seasons. The emission sources of PAHs found in the digestive gland varied from a petrogenic profile observed in winter to a pyrolytic pattern in spring. In the arm, the highest PAH contents were observed in June; nevertheless, levels were always below the regulatory limits established for food consumption. The carcinogenic potential calculated for all the sampling periods in the arm were markedly lower than the ones found in various aquatic species from different marine environments. The results presented in this study give relevant baseline data for environmental monitoring of organic pollution in coastal areas.

Mussels collected on the Cantabrian coasts (before the Prestige oil spill) showed in several zones concentrations below 50 g/kg d.w. which according to Soriano et al (2006) can be considered the background pollution in the region while in other zones values above 200 g/kg d.w. were found which according to these authors reflected the vicinity of certain urban or industrial hydrocarbons sources.…”

This paper reports the first results on alkylphenol pollution in edible bivalves from the Spanish coast. Two sampling campaigns (July 2006 and July 2007) were carried out to determine the concentration of nonylphenol (NP), octylphenol (OP) and eight Polycyclic Aromatic Hydrocarbons (PAHs) in wild mussels (Mytilus Galloprovincialys) and clams (Donax trunculus) at 14 sampling sites along the eastern Mediterranean Spanish coast. The results show that NP is the predominant alkylphenol, being the port of Valencia the most polluted area (up to 147 g/kg wet weight in clams). Moving away from the ports the concentration of NP in bivalves decreased. OP concentration was below its detection limit in most of the studied areas and its maximum concentration (6 g/kg w.w.) was measured in clams from the port of Sagunto. The presence of low levels of PAHs was observed in most of the studied areas. The total PAHs concentration (i.e. sum of the 8 measured PAHs) achieved a maximum value of 10.09 g/kg w.w. in the north coast of Valencia city. The distribution pattern of the individual PAHs showed that both pollution sources petrogenic and pyrolytic were present in the sampled areas. Fluoranthene was the most abundant PAH in mussels while benzo(b)fluoranthene in clams. The maximum concentration of 10 µg/kg w.w. for benzo(a)pyrene established by the European Commission was never reached, indeed sampled bivalves showed concentrations 10 times lower than this reference value. Thus, they can be considered safe for human consumption. Despite the low contamination levels, the results show an overall pollution of bivalves by alkylphenol and PAHs as well as an increment in the number of polluted areas from 2006 to 2007. Thus, periodical sampling campaigns should be carried out to monitor the long-term tendency of these toxic and persistent pollutants.

“…Nieto et al (2006) reported that the maximum concentration of total PAH (13 PAHs) was 5.9 mg/kg dry weight in Mytilus galloprovincialis 2 months after the Prestige oil spill. Soriano et al (2006) also reported that the concentration was above 1,000 to 7,780 μg/kg dry weight in M. galloprovincialis Concentration (ng/g dry) at sites most affected by the Prestige oil spill after 2-3 months. In the Prestige oil spill, several effects on shellfish and other aquatic organisms were reported (Cajaraville et al 2006;Laffon et al 2006;Pérez-Cadahía et al 2004).…”

Following the oil spill accident of the Solar I tanker in 2006 off the coast of Guimaras Island in the Philippines, polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs in some aquatic organisms were investigated at Luzaran in Guimaras and Taklong Islands, which were heavily polluted with spilled oil, immediately and 1 month after the accident. The concentrations of total PAHs were 11.9-52.3 ng/g dry weight in fish. Meanwhile, total PAH concentrations in shellfish were 38.0-3,102 ng/g dry weight in Luzaran and 128-236 ng/g dry weight in Taklong. Pyrene, phenanthrene, and fluoranthene were dominant in most fish and chrysene in all shellfish. Significantly higher concentrations of all alkylated homologs were detected in shellfish than in fish. These differences had two possible causes, that is, the differences between fish and shellfish could be attributed to the uptake routes and/or their metabolizing abilities.
