“…Likewise, different heavy metal levels were observed between various species of fish in similar studies (Karadede et al, 2004;Karadede and Unlu, 2007). It was mentioned that heavy metal levels in different species depend on biometric properties of the fish (Linde et al, 1998;Al-Yousuf et al, 2000), and their feeding habits (Amundsen et al, 1997;Romeoa et al, 1999;Mormede and Davies, 2001;Watanabe et al, 2003). Karadede and Unlu (2000) studied the concentrations of some trace metals in various species from Ataturk Dam Lake (Euphrates, Turkey).…”

The Zn, Cu, As, Cd, Hg and Pb levels of the popular species (Silurus triostegus, Acanthobrama marmid, Aspius vorax, Capoeta trutta, Carasobarbus luteus, Chalcalburnus mossulens and Cyprinus carpio) of Ataturk Dam Lake (Euphrates, Turkey) were studied to estimate the risk of human consumption and pollution of Euphrates River which is important for Turkey, Syria and Iraq. Trace metal amounts differed between the species (P<0.05) even they were living in similar habitats. The variations of measured heavy metals (mg/kg d.w.) were 10.27-19.74 for Zn; 0.101-2.785 for Cu, 0.164-0.279 for As; ND (Not determined)-0.649 for Hg; ND-0.236 for Pb. Cd was not determined during the study. Regarding the Zn, Cu, Cd, and As contents, the samples were safe for human consumption. Mercury and lead were not detected in some of the samples, but their amounts exceeded the limits in S. triostegus and A. marmid, respectively. It was concluded that the fish from Ataturk Dam Lake are not heavily burdened with metals, but they should be controlled periodically to avoid excessive intake of trace metals by human, and to monitoring the pollution of aquatic environment.Keywords: Fish, heavy metal, seafood, freshwater. Atatürk Baraj Gölü (Fırat, Türkiye) Balıklarındaki İz Element Miktarının Belirlenmesi ÖzetTürkiye, Irak ve Suriye için önem taşıyan Fırat Nehri'ndeki kirliliğin ve buradaki yaygın balık türlerinin insan tüketimi açısından riskinin belirlenmesi amacıyla Atatürk Baraj Gölü'ndeki (Fırat, Türkiye) Silurus triostegus, Acanthobrama marmid, Aspius vorax, Capoeta trutta, Carasobarbus luteus, Chalcalburnus mossulens, ve Cyprinus carpio'te Zn, Cu, As, Cd, Hg ve Pb seviyeleri tespit edilmiştir. Farklı türlerin içerdiği iz elementlerin miktarı benzer ortamlarda yaşamalarına karşın farklılık (P<0,05) göstermiştir. Analiz edilen iz elementlerin miktarları Zn için 10,27-19,74; Cu için 0,101-2,785, As için 0,164-0,279; Hg için TE (Tespit edilmemiş)-0,649; Pb için TE-0,236 (mg/kg) arasında değişmektedir. Çinko, Cu, Cd ve As miktarları bakımından örnekler insan tüketimi açısından güvenlidir. Cıva ve kurşun ise bazı örneklerde tespit edilmemiş, ancak Hg miktarı bazı S. triostegus örneklerinde; kurşun ise bazı A. marmid 'lerde sınırları aşmıştır. Atatürk Baraj Gölü'ndeki balıkların ağır metalle önemli düzeyle kontamine olmadıkları, ancak insanların tüketim yoluyla aşırı ağır metal almasını önlemek için bunlarda düzenli kontrollerin yapılması ve su kirliliğinin gözlenmesi gerektiği anlaşılmaktadır.Anahtar Kelimeler: Balık, ağır metal, su ürünü, tatlısu.

“…If we consider brown trout as an indicator of heavy metal contamination in the water environment (Linde et al 1998), the water, sediment and zoobenthos in locality 4 should be the most contaminated by lead, but the reality is different. It may be due to feeding migrations or a consequence of brown trout stocking (this species is stocked yearly at the age of 1+ and 2+).…”

Vítek T., P. Spurn˘, J. Mare‰, A. Ziková: Heavy Metal Contamination of the Louãka River Water Ecosystem. Acta Vet Brno 2007, 76:149-154. Heavy metal contamination of the Louãka River water ecosystem was assessed in July 2005. We analyzed concentrations of T-Hg (total mercury), Cd, Pb, Cr, Cu, Zn, and Ni in water, sediments, zoobenthos, and in the brown trout (Salmo trutta m. fario) muscle and liver tissues (a total of 28 individuals) at four sampling sites. The highest Pb and Ni concentrations (4.634 -12.050 and 0.689 -24.980 mg·kg -1 ) were found in sediments. The zoobenthos was most contaminated by Zn and Cu (0.556 -1.505 and 2.925 -74.300 mg·kg -1 ). The heavy metal contamination of river water was highest in Ni and Cr (0.1 -6.8 and 0.5 -10.0 mg·l -1 ). Concentrations of heavy metals in the brown trout muscle were following (in mg·kg -1 ): Pb 0.108 ± 0.073 -1.010 ± 0.506, Cd 0.003 ± 0.002 -0.026 ± 0.022, Zn 3.956 ± 0.371 -5.801 ± 1.718, Ni 0.058 ± 0.018 -0.102 ± 0.046, Cr 0.028 ± 0.005 -0.073 ± 0.039, Cu 0.329 ± 0.079 -0.437 ± 0.064 and Hg 0.065 ± 0.008 -0.106 ± 0.047. Statistical differences (P < 0.05) in the brown trout muscle were in Pb and Zn. Cd, Cu and Zn were markedly accumulated in the brown trout liver (concentrations 0.107 ± 0.066 -0.223 ± 0.078, 59.973 ± 38.951 -145.800 ± 48.286 and 30.671 ± 3.574 -34.274 ± 7.226 mg·kg -1 ). Humans of 60 kg body mass may consume 1.5 kg of brown trout muscle from the Louãka River weekly without any risk. Adverse influence of the Uniglas distillery on the Louãka River environment contamination by heavy metals was not confirmed.

“…In this study we have chosen brown trout and European eel since we have already established their natural #uctuations in hepatic levels of heavy metals and MT (SaH nchez-GalaH n, 1997; Linde et al, 1999) and assessed the usefulness of these "sh species as biomonitors of aquatic pollution (Linde et al, 1996(Linde et al, , 1998.…”

“…In previous studies, we have already assessed under "eld conditions the endogenous variations of heavy metals and MT levels in brown trout, Salmo trutta, and European eel, Anguilla anguilla (Linde et al, 1996(Linde et al, , 1998SaH nchez-GalaH n, 1997). In the present work, we evaluate in the "eld situation the potential of MT as a bioindicator of heavy metal pollution in brown trout and European eel.…”
