PORSUK VE ENNE BARAJ GÖLLERİ (KÜTAHYA/TÜRKİYE) SEDİMENTİNE BAĞLI AĞIR METALLERİN PULLU SAZANIN (Cyprinus carpio) FARKLI DOKULARINA BİYOAKÜMÜLASYON ORANLARI

Abstract (2. Language): 
In this study, sediment-bound heavy metal levels of Enne and Porsuk Dam Lakes and their bioaccumulation factors (BAFs) to various tissues (Muscle, skin, gill, liver and intestine) of common carp (Cyprinus carpio) were investigated. After per month acclimation period the fingerlings were subjected to one month assay in eight tanks. The analyses of heavy metals (Hg, Cd, Pb, Cu, Zn, Mn, Ni, Fe, Cr, B, Ag and Se) were performed with Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) in Laboratory of Environmental Issues Research and Training Centre, Anadolu University. Hg and B were not encountered in sediments of both Enne and Porsuk Dam Lakes. There were any statistical differences (Except Zn) between heavy metal concentrations of both dame lakes. According to international criterias and Turkish regulations, heavy metal concentrations (Except Ni) in sediment of both dame lakes were markedly below the maximum permissible levels. BAFs of the elements were significantly different. Metal levels in various tissues of the sediment-treated group were generally higher than those of the control group. Althouhg BAFs (from sediments) of some elements were above 1 in some tissues, BAFs of all elements were also markedly below 1 in the muscle tissue.
Abstract (Original Language): 
Bu çalısmada, Enne ve Porsuk Baraj Göl’leri sedimentine bağlı ağır metal seviyeleri ve Cyprinus carpio’nun farklı dokularına (Kas, deri, solungaç, karaciğer ve bağırsak) bioakümülasyon faktörleri (BAF) arastırılmıstır. Bir aylık alıstırma periyodundan sonra, fingerlingler toplam 8 tanklık deney düzeneğinde bir ay süre ile beslenmislerdir. Ağır metal (Hg, Cd, Pb, Cu, Zn, Mn, Ni, Fe, Cr, B, Ag ve Se) analizleri Anadolu Üniversitesi Çevre Mühendisliği Bölümü’nde bulunan İndüktif Eslesmis Plazma-Optik Emisyon Spektroskopi (ICP-OES) ile yapılmıstır. Hem Enne hem de Porsuk Baraj Gölleri sedimentinde Hg ve B elementleri tespit edilememistir. Her iki gölün ağır metal konsantrasyonları arasında (Zn hariç) istatistiksel fark yoktur. Uluslar arası kriterlere ve Türk standartlarına göre her iki gölün sedimentinde ağır metal konsantrasyonları (Ni hariç) izin verilen maksimum seviyelerden önemli derecede düsük bulunmustur. Elementlerin bioakümülasyon faktörleri önemli derecede farklıdır. Sediment muamele edilmis grupların farklı dokularında metal seviyeleri genel olarak kontrol grubundan yüksektir. Bioakümülasyon faktörleri (BAF) bazı dokularda 1’in üzerinde bulunmasına rağmen kas dokusunda bütün elementler için hesaplanan biokümülasyon faktörlerinin 1 den önemli derecede düsük olduğu tespit edilmistir.
