“…Körfezin iç kesimlerinde kirlilik aşırı boyutlara ulaşmış ve körfezin ekolojik dengesinde onarılması güç bozulmalar gözlenmeye başlanmıştır. Bu nedenlerden dolayı 1983 yılında Büyük Kanal Projesi çerçevesinde arıtma tesisi kurma çalışmaları başlatılmış, bu tesisinin büyük bir kısmının 2000 yılında devreye girmesi ile orta ve iç körfezde fiziksel, kimyasal ve biyolojik değişiklikler söz konusu olmaya başlamıştır (Kontaş et al, 2004;Çınar et al, 2006). İzmir iç körfezde yer alan İzmir Limanı'ndan kaynaklanan yoğun gemi trafiğinin de körfez ekosistemi üzerinde olumsuz etkileri vardır.…”

ÖZET: Bu çalışmada, İzmir Körfezi'nde medio-littoral zonda seçilen 4 istasyonda, midye yataklarında dağılım gösteren yabancı Bivalvia türlerinin tespit edilmesi amaçlamıştır. 2014 yılı Kasım ayında alınan örneklerin değerlendirilmesi sonucunda 11 bivalv türü ve bu türlere ait toplam 8200 birey saptanmıştır. Tespit edilen bivalvlerden Anadara transversa, Arcuatula senhousia, Brachidontes pharaonis ve Pinctada radiata yabancı türler olup, araştırmada bu türlerin toplam 122 bireyine rastlanmıştır. Örneklerde juvenil bireyler ile temsil edilen A. transversa, toplamda 65 birey ile en baskın yabancı tür olarak belirlenirken, B. pharaonis ise toplam 12.94 gr ile en yüksek biyomas değerine sahip yabancı tür olmuştur.Anahtar Kelimeler: Bivalvia, İzmir Körfezi, midye yatağı, yabancı tür ABSTRACT: The present study is aimed to determine alien bivalve species on the mussel beds (Mytilus galloprovincialis and Mytilaster minimus) inhabiting the medio-littoral zone of four stations located in Izmir Bay (Aegean Sea). Samplings were performed in November 2014 and as a result, a total of 8200 specimens belonging to 11 bivalvian species were encountered. Of the species determined, Anadara transversa, Arcuatula senhousia, Brachidontes pharaonis and Pinctada radiata were alien ones represented with 122 individuals. Among the alien bivalves, A. transversa that comprised juvenile specimens was the most dominant species with a sum of 65 individuals and B. pharaonis had the highest biomass value (12.94 gr in total) in the area.

“…There have been many studies carried out concerning metal pollution and eutrophication in the Izmir Bay, especially the Inner Bay reported as polluted area in terms of heavy metal, trace elements, inorganic and organic matters [11][12][13][14][15][16][17] following procedure [9]; for each homogenized samples, 0.3 g homogenate (wet weight) was weighed and placed in Polytetrafluoroethylene (PTFE) vessel with 65% nitric acid/30% hydrogen peroxide (4:2). Material was then subjected to a microwave program (Table 1).…”

Comparative study of heavy metals and selenium accumulation in the digestive gland and gills of Mytilus galloprovincialis (Lamarck, 1819) caught in Izmir bay (Turkey) [İzmir Körfezi'nden (Türkiye) yakalanan Mytilus galloprovincialis (Lamarck, 1819)'un sindirim bezi ve solungaçlarındaki ağır metal ve selenyum içeriklerinin karşılaştırması] ABSTRACTObjective: The aim of this study was to evaluate heavy metals (Cr, Fe, Ni, Cu, Zn, As, Cd, Hg, Pb) and selenium levels in digestive gland and gill tissues of wild Mediterranean mussel Mytilus galloprovincialis (Lamarck, 1819) collected from four locations in Izmir Bay. Methods: A total of 180 samples of the wild Mediterranean mussel M. galloprovincialis with shell length of 50-60 mm were collected from four locations. Inductively coupled plasmamass spectroscopy was used to determine heavy metals and selenium concentrations in mussel samples after microwave digestion process. March 5, 2015] and the effects of these plants on ecosystem of the Izmir bay have been monitored [15,18]. Results ICP-MS as a technique for the inorganic trace analysisshows an excellent sensitivity for a large numbers of elements of interest and the speed of measurement makes it suitable for routine, multielement determinations at trace and ultratrace levels. Important characteristic is the ability to detect and measure concentrations of analyzed elements at very low levels [19,20].The aim of this study was to quantify and compare heavy metals and selenium in digestive glands and gill tissues of M. galloprovincialis collected from four locations in Izmir Bay. Material and MethodsIzmir Bay is located in the eastern Aegean Sea between latitudes of 38°20' and 38°42' N and longitudes of 29°25' -27°10' E. It is one of the largest natural bays of the Mediterranean. Izmir which is the third largest city in Turkey is located at the west part of the Anatolian peninsula and it is an important industrial and commercial center and a cultural focal point. The Izmir Bay has been considered dividing into three areas as Outer, Middle and Inner Bay according to their physical characteristics. The main industries in the region include food processing, oil, soap and paint production, chemical industries, paper and pulp factories, textile industries and metal processing [21][22][23].

“…In the outer bay, the Gediz River is the main source of pollution. Physico-chemical characteristics of the bay have been recently well documented: water and sediment quality by Kucuksezgin (1996), Aksu et al (1998) and Atgin et al (2000); hydrogen suphide and odour problem by Müezzinoǧlu et al (2000); physical features by Sayın (2003); nutrient and iron enrichment by Bizsel and Uslu (2000); eutrophication processes by Balci et al (1995), Bizsel et al (2001) and Kontas , et al (2004).…”
