“…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.

“…Karena hal ini memiliki implikasi bagi kesehatan manusia lewat konsumsi makanan dari laut (seperti, ikan, kerangkerangan dan udang-udangan). Konsentrasi residu logam dalam jaringan biota akan selalu berfluktuasi dipengaruhi antara lain, umur dan ukuran biota (Al-Yousef et al, 2000), kebiasaan makan biota atau tingkat trofik dalam jaringan (Watanabe et al, 2003), serta spesies atau jenis biota (Qugun et al, 2005;Calta dan Canpolat, 2006, Abdallah andAbdallah, 2008). Tabel 4 menyajikan bahwa konsentrasi residu logam dalam jenis-jenis ikan cukup bervariasi, namun jika dianalisis lebih dalam menunjukkan tren yang sangat nyata bahwa residu logam berat pada jaringan kelompok ikan jauh lebih rendah dibanding pada kelompok kerangkerangan.…”

Kelabat Bay is a semi enclosed waters divided into two parts, i.e., outer part of Klabat bay facing the Natuna Sea (T Luar) and inner Kelabat bay surrounded by human activities and five river mouths (T Dalam)), Cu (2,50 mg kg -1 ) dan Zn (13,64 mg kg -1 ). Konsentrasi logam Pb, Cu dan Zn di sedimen T Dalam dapat mencapai dua kali lipat lebih tinggi dibanding T Luar, namun demikian ketiga konsentrasi logam tersebut tidak dipengaruhi oleh musim. Sebaliknya, konsentrasi logam Cd cenderung merata di sedimen dan sangat dipengaruhi musim. Konsentrasi logam Pb, Cd, Cu dan Zn pada ikan umumnya lebih rendah dibanding pada jenis kerang-kerangan. Akumulasi Pb dan Cu tertinggi oleh siput gonggong Strombus canarium, dan Cd dan Zn tertinggi oleh kerang darah Anadara sp.

“…Humans ingest eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) mainly through intake of fish. But, previous research also has shown that freshwater fish may have a high level of nocuous chemicals, such as methylmercury, polychlorinated dibenzo-p-dioxins, and dibenzofurans, organochlorine residues, and other contaminants (Dai et al, 2002;Watanabe et al, 2003;Hirunwatthanakul et al, 2006;Cheng et al, 2013;Eqani et al, 2013;Saengsawang et al, 2013;Wang et al, 2013;Lee et al, 2014), and some of them have been shown to be mutagens or animal carcinogens. Because contaminants and nutrients always coexist in freshwater fish, the risk :http://dx.doi.org/10.7314/APJCP.2014.15.18…”

To investigate the association between intake of freshwater fish and their fatty acids and the risk of breast cancer in Chinese women, we conducted a case-control study with 669 cases and 682 population-based controls in Jiangsu Province of China. A structured questionnaire was used to elicit detailed information. Unconditional logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Total freshwater fish intake was linked to decrease in the adjusted OR for breast cancer, but without dose-dependence. Analyses by freshwater fish species showed that consumption of black carp and silver carp was inversely related to breast cancer risk, with adjusted-ORs for the highest intake category of black carp (≥500g/month) of 0.54 (95%CI=0.33-0.92; P trend <0.002) and for silver carp (≥1000g/month) of 0.19 (95%CI=0.11-0.33; P trend <0.001). In contrast, consumption of crucian carp was positively related to breast cancer risk, with an adjusted OR for the highest intake category (≥1000g/month) of 6.09 (95%CI=3.04-12.2; P trend <0.001). Moderate intakes of SFA, PUFA, n3-PUFA and n6-PUFA from freshwater fish may decrease the risk of breast cancer among premenopausal women. The findings of this study suggest that intake of freshwater fish and their fatty acids may modify risk of breast cancer, and that different species of freshwater fish could have a different actions on breast cancer risk. Future epidemiologic studies are needed to know the effects of freshwater fish intake on breast cancer risk and the cause of these effects.
