Makale Kodu (Article Code): KVFD-2009-982 SummaryThe purpose of this study is to determine some heavy metals in muscle tissues of fish collected from the Middle Black Sea Coast of Samsun, Sinop, Terme, Fatsa and Ordu in Turkey. A total of 1650 fish samples including Trachurus trachurus, Alosa caspia, Pomatomus saltatrix, Mullus barbatus, Spicara smaris, Engraulis encrasicolus, Gobius cephalarges, Sarda sarda, Merlangius euxmus and Psetta maxima were used as material. Metal concentrations in fish samples were measured by atomic absorption spectrophotometry. The average value of metal concentrations in fish samples were determined as follows: 2.38 μg/g for Cu, 5.41 for Mn, 26.06 for Fe, 3.40 for Ni, 25.74 for Zn, 0.77 for Pb and 0.022 for Cd, but Hg was not detected. These values were compared with FAO/WHO standards and metal concentrations in fish samples were found to be lower than the maximum permissible levels, but lead level was found to be higher. Keywords: Heavy metal, Atomic absorption spectrometry, Fish Orta Karadeniz Bölgesinden Toplanan Balıklarda Ağır Metal Düzeylerinin Belirlenmesi ÖzetBu çalışma Türkiye'nin Orta Karadeniz kıyılarındaki Samsun, Sinop, Terme, Fatsa ve Ordu yörelerinden toplanan balık kas dokularında bazı ağır metal düzeylerinin araştırılması amacıyla yapıldı. İstavrit, tirsi, çinekop, barbun, izmarit, hamsi, kaya balığı, palamut, mezgit ve kalkan olmak üzere toplam 1650 adet balık örneği materyal olarak kullanıldı. Balıkta metal konsantrasyonu atomik absorbsiyon spektrometresi kullanılarak belirlendi. Balık örneklerinde ortalama ağır metal konsantrasyonları: Cu: 2,38, Mn: 5,41, Fe: 26,06, Ni: 3,40, Zn: 25,74, Pb:0,77 ve Cd: 0,022 μg/g olarak bulundu, Hg ise tespit edilemedi. Elde edilen bu değerler FAO/WHO standartları ile karşılaştırıldığında balık örneklerinin maksimum kabul edilebilir limitleri aşmadığı, fakat kurşun düzeyinin limitlerin üzerinde olduğu belirlendi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
