“…These results support the hypothesis that the liver is the major storage and regulatory tissue involved in Cu homeostasis. Similar results have been observed in sea bream (Wong et al, 1999), rainbow trout (Handy, 1993;Miller et al, 1993), tilapia (Pelgrom et al, 1995;Ay et al, 1999), and the Senegales sole (Arellano et al, 1999). Therefore, after Cu exposure, the liver of olive flounder is clearly a more important storage tissue than other tissues.…”

Olive flounder, Paralichthys olivaceus were exposed to waterborne Cu (control, 50, 80, 150, and 320 µg/L) for 30 days and then depurated for 20 days to investigate the effects of waterborne Cu exposure on growth, accumulation, and elimination. The weightspecific growth rate was significantly negatively related to waterborne Cu concentrations at 150 and 320 µg/L. The order of Cu accumulation in different tissues of exposed fish was liver>intestines>gills>kidneys>muscle, suggesting that the liver is more important than other tissues for the storage of Cu in olive flounder. The accumulation factor for the gills, intestines, liver, and muscle increased with increasing exposure time, and accumulation was negatively related to exposure concentration for the gills, kidneys, and muscle. Cu concentrations in the gills, intestines, and liver continuously decreased for 20 days of depuration. The fastest elimination rate occurred in the intestines at all exposure concentrations, and the order of Cu elimination in the different tissues was intestines>liver>gills.

“…Therefore estimation of the trace metals in fish became important to estimate freshwater pollution and the risk potential of human consumption (Dural et al, 2007;Göksu et al, 2003). Likewise, many studies have been published on the trace metals in freshwater fish (Alam et al, 2002;Ay et al, 1999;Chi et al, 2007;Farkas et al, 2000;Gumgum et al, 1994;Yang et al, 2007). There are a few studies on trace metals in some of the fish caught from Ataturk Dam Lake (Karadede and Unlu, 1998;Karadede et al, 1997;Karadede et al, 2004).…”

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.

Acute toxicity estimates of copper (Cu) and zinc (Zn) in juvenile Chinese sturgeon were studied in the Yangtze River estuary and using the static test method to assess Cu and Zn toxicity. The results showed that Cu was more severely toxic to Chinese sturgeon than Zn. The Cu LC 50 after 24-, 48-, 72-and 96-h , respectively. The liver was the major accumulation site for Cu. Cu content in the liver of juveniles in the control group (no Cu) was the highest, followed by the gills, whereas the lowest content was detected in cartilage. The fastest accumulator of Cu was the liver, followed by the stomach, and cartilage and skin had the lowest contents. Superoxide dismutase (SOD) and catalase (CAT) activities in the liver tissues of juveniles were relatively low for the first 24 h, but the activities recovered gradually from 24 to 48 h and decreased after 48 h to levels lower than the contro1 group. These changes in SOD and CAT activities indicate that juvenile Chinese sturgeon were severely affected by Cu. These data show that Chinese sturgeon juveniles face the threat of Cu contamination and this alerts officials to the dangerous situation.
