BIOACCUMULATION RATIOS OF SEDIMENT-BOUND HEAVY METALS OF PORSUK AND ENNE DAM LAKES (KÜTAHYA/TURKEY) TO DIFFERENT TISSUES OF COMMON CARP (Cyprinus carpio)

Abstract

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.
