Accumulation of some heavy metals in Hysterothylacium aduncum (Nematoda) and its host sea bream, Sparus aurata (Sparidae) from North-Eastern Mediterranean Sea (Iskenderun Bay)
(Springer, 2011) Dural, Meltem; Genc, Ercument; Sangun, M. Kemal; Guner, Ozlem
The sea bream's nematode and Sparus aurata, sampled from the Iskenderun Bay, Mediterranean, in March 2008 were analyzed by inductively coupled plasma-atomic emission spectrometry for their some heavy metal (Cd, Cr, Cu, Fe, Hg, Mn, Mg, Pb, and Zn) levels. The metal concentrations of the parasites were compared to different organs (liver, muscle, gill, intestine, and skin) of the fish hosts. There were significant differences in Cd, Cr, Cu, Fe, Mn, Zn, Hg, Mg, and Pb concentrations in tissues of fish and its parasite. The parasite Cd, Cu, and Pb concentration was higher than the other tissues. Furthermore, significant differences were detected in the heavy metal accumulations between the parasitized and unparasitized fish tissues in Cd, Cu, Hg, and Pb concentrations. The Cd, Hg, and Pb concentrations were found in fish muscle at mean concentrations over the permissible limits proposed by the Food and Agriculture Organization.

Bioaccumulation of some heavy metals in different tissues of Dicentrarchus labrax L, 1758, Sparus aurata L, 1758 and Mugil cephalus L, 1758 from the Camlik lagoon of the eastern cost of Mediterranean (Turkey)
(Springer, 2006) Dural, Meltem; Goksu, M. Z. Lugal; Ozak, Argun Akif; Derici, Baris
In this study, bioaccumulation of the heavy metals (Fe, Zn, Cd) in the liver, gill, gonad and muscle tissues of Dicentrarchus labrax, Mugil cephalus and Sparus aurata were investigated seasonally. Camlik is the important fisheries lagoon located in The Iskenderun Bay, Mediterranean cost of Turkey. Due to heavy industrial and agricultural activities in the region, the bay has the polluted coastal waters of Turkey. Therefore, the levels of cadmium, zinc, iron were determined in the muscle in each species because of its importance for human consumption and also the liver, gill, gonad were analysed since these organs tend to accumulate metals. Heavy metal levels were found generally higher in the liver and gill than the gonad and muscle tissues in three species; the levels of all metals in a given tissue were generally higher in Mugil cephalus than the other two species. Data collected in this study suggest that Camlik lagoon is affected by a relatively metal pollution. The concentrations of Zn concentrations in the muscle tissues exceeded the acceptable levels for a food source for human consumption and other metals in the edible parts of the investigated fish were in the permissible safety levels for human uses.
Çamlık Lagünü (Karataş, Adana), seston, bentoz ve sedimentinde mevsimsel ağır metal değişimi
(2006) Dural, Meltem; Göksu, Münir Ziya Lugal
Bu çalışmada, Akdeniz Bölgesinde bulunan ve yoğun kirlenme tehdidi altındaki önemli sulak alanlardan, Çamlık lagününde seston, bentoz ye sediment örneklerinde ağır metallerden Pb, Cu, Zn, Cd, Fe'in birikim miktarları ve bunların mevsimsel değişimi belirlenmiştir. Örneklerdeki ağır metal konsantrasyonları yaş parçalama yöntemi uygulandıktan sonra FLAAS ve GFAAS kullanılarak ölçülmüştür. Son yıllarda bölgeye düşen yağış miktarındaki azalma, tatlı su ve deniz suyu kaynağının yetersizliği, sedimantasyon, yeni yerleşim alanları ve çevrede bulunan tarım arazileri ile birlikte yüksek tuzluluk lagünün ekolojik dengesinin bozulmasında önemli etkenler olarak düşünülebilir. Çalışmada belirlenen bulgular değerlendirildiğinde en çok Zn (2295,06 $mu gg^{-1}$ ) ve Cd (17,06 $mu gg^{-1}$ )'un sestonda; Fe ( 30441,7O $mu gg^{-1}$) ve Pb (67,29 $mu gg^{-1}$ )'un sedimentte; Cu (72,24 $mu gg^{-1}$ )'ın ise bentozda biriktiği görülmüştür. Araştırma sonucunda lagündeki seston, sediment ve bentozda ağır metal miktarlarının genelde mevsimlere bağlı düzenli değişimler göstermediği görülmüştür.

(Medwell Online, 2010) Dural, Meltem; Bickici, Esra
Samples of Upeneus pori and Upeneus molucensis were collected in the Iskenderun Bay, Northeastern Mediterranean coast of Turkey the contents of Fe, Zn, Al, Cu, Pb, Mn, Ni, Cr, Cd in the liver, skin and muscle tissues were determined by ICP-AES. Statistical comparisons revealed that metal concentrations were significantly different in each tissue from different fish species. Al, Pb, Ni and Cd concentrations detected in the Upeneus moluccensis increased in following order; Muscle < Liver < Skin, for Fe, Zn, Cu and Cr Muscle < Skin < Liver. Al, Pb and Fe concentrations detected in the Upeneus port increased in following order; Muscle < Skin < Liver, for Zn, Muscle < Liver < Skin, for Ni skin < muscle and for Cr Skin < Muscle < Liver. Pb and Ni concentrations didn't show any significant differences between the tissues for this species. The concentrations of these metals measured in the muscle of the three species studied generally were lower than the levels issued by FAO and Turkish legislations. Only the Pb levels in two species and Cd levels in Upeneus molucensis were higher than the acceptable values for human consumption designated by various health organisations.

Element concentrations in the swimbladder parasite Anguillicola crassus (nematoda) and its host the European eel, Anguilla anguilla from Asi River (Hatay-Turkey)
(Springer, 2008) Genc, Ercument; Sangun, M. Kemal; Dural, Meltem; Can, M. Fatih; Altunhan, Cem
The European eel's swimbladder nematode, Anguillicola crassus, sampled from the Asi River (Orontes River) in Antakya (Hatay, Turkey) in May 2006 were analysed by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) for their some heavy metal (Cd, Cr, Cu, Fe, Hg, Mn, Pb and Zn) levels. The metal concentrations of the parasites were compared to different organs (swimbladder, liver, muscle and skin) of the fish hosts. The parasite contained statistically highly significantly amounts of Fe (P < 0.05). The iron level of nematode was up to 25.52 times than the muscle of its host, Anguilla anguilla. However, bioconcentration of Cd, Cr, Cu, Hg, Mn, Pb, Zn were detected in the A. crassus and it contained no statistically differences with the other tissues of its host, the eel (P > 0.05). Furthermore, no significant differences were detected in the heavy metal accumulations between the parasitized and un-parasitized fish tissues. The analysed metals (Cd, Cr, Cu, Fe, Mn, Pb and Zn) were found in fish muscle at mean concentrations under the permissible limits proposed by FAO.

Investigation of heavy metal levels in economically important fish species captured from the Tuzla lagoon
(Elsevier Sci Ltd, 2007) Dural, Meltem; Goksu, M. Ziya Lugal; Ozak, Argun Akif
Two hundred fish samples were collected seasonally from November 2000 to December 2001 from the Tuzla Lagoon. Heavy metal (Cd, Pb, Cu, Zn, and Fe) concentrations were measured in the muscle, gill, liver and gonad of three fish species (Sparus aurata, Dicentrarchus labrax and Mugil cephalus). The concentrations of heavy metals were determined by using flame atomic absorption spectrophotometry (FLAAS) and graphite furnace atomic absorption spectrophotometry (GFAAS) after wet digestion method. Our results indicated that all heavy metals were found the highest in muscle tissue in S. aurata. Although Cd and Zn were found in spring, Fe, Cu, and Pb were observed in winter. In addition, D. labrax and M. cephalus accumulated lowest heavy metals in muscle during this study. While the highest concentrations of Zn, Fe and Cu were measured in the liver of M. cephalus, the highest levels of Cd and Pb were determined in gill tissue of M. cephalus. However, in some seasons Zn, Cd and Pb concentrations in the muscle were higher than the maximum levels set by law. Especially, for each species in spring high levels of Zn were measured, for D. labrax and M. cephalus in spring and for S. aurata in winter high levels of Pb were measured; for S. aurata in spring and for M. cephalus in winter high levels of Cd were measured for human consumption.

Trace metals in the shells of blue mussels (Mytilus edulis) from the Poland coast of Baltic sea
(Springer, 2008) Protasowicki, Mikolaj; Dural, Meltem; Jaremek, Joanna
In this study, bioaccumulation of the heavy metals (Hg, Pb, Cd, Cu, Zn, Cr, Ni, Fe, Mn, V, Li, Al) in the shells of Mytilus edulis were investigated. Shells of Mytilus edulis were collected in May to September 2005 from 12 stations on the Polish coast of Baltic Sea. At each sampling sites 17-330 different size of shells were collected during 2005, respectively. Due to heavy industrial activities in the region, the bay has the polluted coastal waters of Poland. Shells were analysed by ICP AES and Coleman MAS 50 CV atomic absorption spectrometer. As expected from the similarity found between the relationships of metal content length and dry the concentrations of the different metals in the shells did not seem to depend on the shell length. No significant differences were detected in metal concentration between different shell lengths. Given their geographical distributions, as well as their abilities to show up spatial and temporal changes in metal bioavailabilities confirmed here, it is concluded that the mussel M. edulis a suitable candidate to be used in biomonitoring surveys of the Poland coast of Baltic.
Variations of heavy metal levels of seston benthos and sediment seasonally in Camlik Lagoon (Karatas, Adana)
(Ege Univ, 2006) Dural, Meltem; Goksu, M. Z. Lugal
In this research, samples were taken seasonally from the Tuzla Lagoon and heavy metal (Cd, Pb, Cu, Zn, Fe) concentrations in the sediment, seston and benthos were measured. The concentrations of heavy metals in the seston, benthos and sediment samples were determined by using Flame Atomic Absorption Spectrophotometry (FLAAS) and Grafite Furnace Atomic Absorption Spectrophotometry (GFAAS) after wet digestion method. In recent years, decrease on the amount of local rainfalls, the lack of fresh and seawater sources, sedimentation, agricultural fields around the region, new domestic places and increasing salinity can be thought as the reasons of loosing the ecological balance in the lagoon. Results in this study showed that, in general, maximum bioaccumulation of Zn (2295,06 mu gg(-1)) and Cd (17,06 mu gg(-1)) was detected in seston, Fe (30441,70 mu gg(-1)) and Pb (67,29 mu gg(-1)) in sediment and maximum Cu (72,24 mu gg(-1)) levels were detected in benthos. As the conclusion, changes of detected levels of heavy metals on seston, sediment and benthos are seasonally independent.
