“…Several authors concluded that the atmosphere is an important vector for PAH inputs to the Mediterranean waters, atmospheric inputs being higher than riverine inputs in some basins (Castro-Jiménez et al, 2012;Tsapakis et al, 2006;Tsapakis and Stephanou, 2005). Diagnostic PAH ratios applied to sediments from diverse geographical areas (Gulf of Gdansk; El-Menofiya governorate in Egypt; in the lagoon system Orbetello, Central Italy; Persian Gulf; coast of Aliaga, Turkey; Izmir Bay, Turkey; in Esquimalt and Victoria, BC, Canada; Abu Qir Bay, Egyptian Mediterranean Sea; western coast of Alexandria, Egypt) have also shown that deposition of compounds produced by combustion are one of the main sources (Nasr et al, 2010;Neşer et al, 2012;Rogowska et al, 2010;Wolska et al, 2011;Yunker et al, 2012;Zhang et al, 2012). September and November appear to show mixed contamination sources which might be caused by superimposing petrogenic and pyrolytic sources at the sampling site.…”

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.

“…However, in the Mexico study phenanthrene was the predominant PAH congener (25%) detected, followed by pyrene and fl uorine [14]. In Aliağa Bay, Turkey, sediments were found to be polluted with toxic PAH compounds, and this has been attributed to the activities going on in the bay, including ship breaking, plus steel and petrochemical industries [15]. Polycyclic Aromatic Hydrocarbons (PAHs) were also detected in sediments of the Cotonou coastal zones (Benin) and in Aquitaine sediment samples (France).…”

“…The Aliağa and Nemrut Bay are very important area in the Eastern Mediterranean and pollution of the bays has been searched by several authors (Sponza and Karaoğlu, 2002;Esen et al, 2010;Neşer et al, 2008;2012a;2012b). The level of metals in surface sediments were compared with the other areas from world oceans (Table 6).…”

“…The Aliağa Bay is one of the most important ship recycling zone of the Mediterranean together shipping activity, shipbreaking industry, steel works and petrochemical complexes (Neşer et al, 2008).There are iron-steel factories, coal storage yards, fuel storage yards, fertilizer factory, natural gas power plant, electrical substation, small industrial areas and other medium and small establishments in region which cause heavy metal pollution (Sponza and Karaoğlu, 2002;Esen et al, 2010). The Aliağa Bay is contaminated by heavy metal, polycyclic aromatic and aliphatic hydrocarbons (PAHs) (Neşer et al, 2012a(Neşer et al, , 2012b. TheNemrut Bay, the neighboring marine environment of Aliağa town, is a subsystem within the Çandarlı Bay ecosystem and connects to the northern Aegean Sea.The Nemrut Bay is considered with anthropogenic pollution and sediments from the Nemrut Bay is highly contaminated by Hg, Pb, As and Zn .…”

The spatial distribution of modern dinoflagellate cysts was studied, with the purpose of understanding the impact from industrial pollution and sediment characteristics. Eight surface sediment samples were collected to analysis of the spatial distribution of dinoflagellate cysts from two industrially polluted areas: Aliağa and Nemrut Bay (Eastern Mediterranean). A total of 42 dinoflagellate cyst morphotype were identified and total cyst abundance ranged between 11 and 2543 cyst g -1 dry weight sediment at sampling points. The cyst assemblages were represented by cyst of Gymnodinium nolleri, Alexandrium affine type and Lingulodiniumma chaerophorum. The higher cyst concentration was recorded at mostly Aliağa Bay stations however the higher cyst diversity was found at Nemrut Bay stations. Total cyst concentration and autotrophic cyst concentration indicated metal pollution in the sampling areas whereas total number of cysts had no correlation with any metal levels in the sediment except Cr. The distribution of dinoflagellate cysts also showed correlation with sediment structure in Aliağa and Nemrut Bay.Keywords: Resting cyst, heavy metals, sediment, Eastern Mediterranean. Endüstriyel Kirliliğin Etkisindeki Aliağa ve Nemrut Körfezi Modern Dinoflagellat Kist Topluluğu ÖzetAliağa ve Nemrut Körfezi'nde (Doğu Akdeniz) endüstriyel kirlilik ve sediment karakteristiklerinin etkisini anlayabilmek amacı ile modern dinoflagellat kistlerinin uzamsal dağılımı çalışıldı. Sekiz yüzey sediment örneği endüstriyel kirlilik içeren bu alanlardan toplanarak dinoflagellat kistlerin uzamsal dağılımları analiz edildi. Örnekleme noktalarında toplam 42 dinoflagellat kist morfotipi belirlendi ve toplam kist bolluğu 11 ile 2543 kist g -1 kuru sediment ağırlığı olarak bulundu. Kist topluluğu Gymnodinium nolleri, Alexandrium affine tip ve Lingulodinium machaerophorum tarafından temsil edildi. Aliağa Körfezi istasyonlarında kist konsantrasyonu daha yüksek iken Nemrut Körfezi istasyonlarında kist çeşitliliği daha yüksek kaydedildi. Toplam kist konsantrasyonu ve ototrofik kist konsantrasyonu örnekleme alanında metal kirliliğini işaret etmesine rağmen toplam kist sayısı Cr hariç herhangi bir metalle bağlantılı değildir. Bununla birlikte dinoflagellat kist dağılımının Aliağa ve Nemrut Körfezi sediment yapısı ile ilişkili olduğu gözlenmiştir.Anahtar Kelimeler: Kalıcı kist, ağır metal, sediment, Doğu Akdeniz.
