“…In the study area, the Aliağa Bay sediment was found muddy except station 1which is located in the river flows. The Nemrut Bay, in station 5 and 6 were mainly muddy, station 7 and 8 contains mostly sand and these result showed similarities with Esen et al (2010). The higher total cyst abundance observed where the sediment contains mud and dinoflagellate cysts abundance changed depends on the sediment type for the Aliağa and Nemrut Bay.…”

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.

Abstract:The concentrations of Zn, Cr, Cu, As, Cd, and Pb in sediment cores collected from a representative riverine wetland located in the Huaihe River watershed, China, dramaticlly increased from the bottom to upper layer of the cores. Application of principal component analysis (PCA) and enrichment factor (EF) suggested that heavy metals might primarily have been derived from the inflow of contaminated water from an industrial park and agricultural region. Component 1 of the PCA was dominated by Zn, Cr, Cu, Cd, and Pb, while Component 2 was dominated by As. Metals' high concentrations and EF values showed that the anthropogenic pollutants have increased sharply in recent years and reflect the continuous development of industry and agriculture in the region of the wetland, with a corresponding dramatic deterioration of the environment due to constant effluent of pollutants. Cd exerted the highest potential ecological risk of individual metals of sediment cores. Additionally, integrated RI values for all metals indicated that sediments possessed low ecological risk from the bottom to about 6 cm depth of the cores, moderate ecological risk from about 5 cm depth upwards, then considerable ecological risk from 4 cm depth to the top layer of the sediment cores, which demonstrates a continuous deterioration of environmental quality in recent years in this region.

“…Trace metals did not show strong seasonal variations. Gavriil and Angelidis (2005) The heavy metal content of the sediments in Nemrut Bay has been studied by Esen et al (2008). Contamination factors (CF) and Metal Enrichment Factors (EF) have been calculated.…”

“…Pb and As had very high contamination levels where there were considerable Zn contamination in most of the sediment samples [39]. Hg concentrations corresponded to very high contamination and the elevated enrichment levels of Pb (2.03-16.06) and Zn (1.08-8.52) indicated anthropogenic pollution (Esen et al, 2008). …”

ÖZET (Hg, Cd, Pb, Cr, Cu, Zn, Mn, Ni, Fe, Mg) ABSTRACT Direct discharges of domestic and industrial wastewaters to the coastal zone of Aegean Sea are an important concern. Design of an environmental baseline assessment program prior to any coastal development is a crucial part of the feasibility studies due to the complexity of the coastal dynamics.The background biogeochemical status of the Nemrut Bay's water column was set to assess the impact of a proposed industrial discharge. The seawater samples were collected on seasonal bases representing winter (mixed water column) and summer (stratified) conditions, and were analyzed for dissolved heavy metal ions (Hg, Cd, Pb, Cr, Cu, Zn, Mn, Ni, Fe, Mg)
