Dikenli Yılan Balığı (Mastacembelus mastacembelus Banks & Solander, 1794)'nın Kas Dokusunda Bazı Ağır Metal Miktarlarının Belirlenmesi

Bu çalışmada, Keban Baraj Gölü'nde yaşayan dikenli yılan balığı (Mastacembelus mastacembelus) kas dokusunda bazı ağır metallerin birikim düzeyleri araştırıldı. Bu amaçla, balıkların yaşam bölgesinden alınan su örneklerinde ve balıkların kas dokusunda bakır (Cu), demir (Fe), çinko (Zn), krom (Cr), kadmiyum (Cd) ve kurşun (Pb) elementlerinin birikim düzeyleri araştırıldı. Pb elementinin miktarı Endüktif Eşleşmiş Plazma Optik Emisyon Spektrometre (ICP-OES) cihazının okuma duyarlılığının altında olduğundan belirlenemedi. Su örneklerindeki ağır metal konsantrasyonlarının mevsimlere bağlı olarak değiştiği tespit edildi. M. mastacembelus'un kas dokusunda tespit edilen ağır metallerin birikim oranlarının balığın vücut ağırlığı, vücut uzunluğu ve eşeyine bağlı olarak değişiklik gösterdiği tespit edildi. Sonuç olarak, M. mastacembelus'un kas dokusunda tespit edilen ağır metal konsantrasyonlarının Çevre Koruma Ajansı (EPA), Gıda ve Tarım Örgütü (FAO) ve Türk Gıda Kodeksi (TGK)'nin önerdiği kabul edilebilir ağır metal değerlerinin altında olduğu belirlendi. Bu çalışmayı, 1432 nolu münferit araştırma projesi olarak destekleyen Fırat Üniversitesi Bilimsel Araştırma Projeleri (FÜBAP) Koordinatörlüğü'ne teşekkür ederiz.

Determination of Some Heavy Metals in the Muscle Tissue of Spiny Eel (Mastacembelus mastacembelus Banks & Solander, 1794)

In this study, the levels of some heavy metals in the muscle tissue of spiny eels (Mastacembelus mastacembelus) living in Keban Dam Lake were investigated. For this purpose, the levels of copper (Cu), iron (Fe), zinc (Zn), chromium (Cr), cadmium (Cd) and lead (Pb) were investigated in the muscle tissue of spiny eels and in their surrounding water. The Pb was not determined due to being below of Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) detection limit. The concentrations of heavy metals in the water samples were found to vary by season. It was found that the levels of heavy metals detected in muscle of M. mastacembelus varied depending on the body weight, body length and sex of the fish. In conclusion, it was determined that the levels of heavy metals detected in muscle tissue of M. mastacembelus were below the acceptable values suggested by Environmental Protection Agency (EPA), Food and Agriculture Organization (FAO) and Turkish Food Codex (TGK).
