Determination of trace metal levels in sediment and five fish species from lakes in Tokat, Turkey

In this study, concentrations of trace metals in five fish species (Cyprinus carpio, Capoeta tinca, Leiciscus cephalus, Carassius gibelio and Silurus glanis) and sediments collected from some lakes in Tokat were determined by atomic absorption spectrometry. The fish species and sediment samples were collected from six lakes (Bedirkale, Boztepe, Belpınarı, Avara, Ataköy and Akın) in Tokat, Turkey in spring and summer during 2003–2004. The samples were digested with a microwave digestion system. The maximum Fe, Mn, Zn, Cu, Pb, Cr and Ni concentrations of sediment samples were 2138, 232, 38.9, 8.2, 7.0, 10.7 and 55.4 μg/g, respectively. The maximum Fe, Zn, Cu, Pb, Cr, Mn and Ni concentrations of the fish samples were 167, 48.6, 3.6, 2.8, 1.6, 64.3 and 5.6 μg/g, respectively.
