Keban Baraj Gölü’nün çeşitli bölgelerinden yakalan Capoeta trutta’nın farklı dokularındaki demir, mangan, kurşun, nikel ve civanın konsantrasyonları indüktif olarak eşleşmiş plazma optik emisyon spektrometresi (ICP-OES) ile belirlenmiştir. Demirin konsantrasyonu, Ağın (S4) istasyonunda yakalanan balıkların kası hariç tüm dokulardaki tüm diğer metal seviyelerinden daha yüksek bulunmuştur. Tüm balık dokularında Fe, Mn, Pb ve Ni konsantrasyonları, kastaki Ni hariç (P>0.05), istasyonlar arasında istatistiksel açıdan önemli ölçüde değişmiştir (P<0.05). Pertek (S1), Koçkale (S2) ve Gülüşkür (S3)’den yakalan balıklar, S4 istasyonundan yakalananlarla karşılaştırıldıklarında farklı dokularda önemli bir şekilde daha yüksek metal seviyeleri sergilemişlerdir. Demir (1064.67±487.06 mg kg-1), Mn (143.42±14.14 mg kg-1), Pb (18.27±1.25 mg kg-1), Ni (11.32±1.40 mg kg-1) ve Hg (30.42±11.04 mg kg-1)’nın en yüksek seviyeleri, sırasıyla karaciğer (S3), solungaç (S2), karaciğer (S2), solungaç (S2) ve böbrek (S3) dokularında elde edilmiştir. Sonuçta, Keban Baraj Gölü’nden elde edilen balıkları tüketen kişilerdeki olası sağlık sorunlarından sakınmak için, tüm dönemlerde bu baraj gölündeki metal birikimi ve su ortamı kirlenmesinin yakın bir şekilde izlenmesi önerilir.

Some Metal Levels in Gill, Liver, Kidney and Muscle Tissues of Capoeta trutta (Heckel, 1843) in Keban Dam Lake (Euphrates-Turkey)

Öz

Concentrations of iron, manganese, lead, nickel, and mercury in different tissues of Capoeta trutta caught from various locations of Keban Dam Lake were determined by inductively-coupled plasma optical emission spectroscopy (ICP-OES). The concentrations of Fe were higher than that of all other metals in all tissues except for muscle of fish captured at Agin (S4). Concentrations of Fe, Mn, Pb and Ni varied significantly among sites in all fish tissues (P<0.05), except Ni in muscle (P>0.05). Fish caught from Pertek (S1), Kockale (S2) and Guluskur (S3) exhibited significantly higher levels of the metals in different tissues as compared to those caught at S4 site. The highest level of Fe (1064.67±487.06 mg kg), Mn (143.42±14.14 mg kg), Pb (18.27±1.25 mg kg-1), Ni (11.32±1.40 mg kg-1) and Hg (30.42±11.04 mg kg-1) were obtained from liver (S3), gill (S2), liver (S2), gill (S2) and kidney (S3) tissues, respectively. Close monitoring of metal accumulation and aquatic pollution of the Keban Dam Lake for all seasons is recommended to avoid possible health hazards of consumers of fish from this lake
