Present study assessed the heavy metal accumulation in muscle and gill tissues of some fish species from Batlama stream in Giresun Coast. Heavy metal levels in analyzed fish were found as Co: 1.47-1.64 Cr: 0.09-0.36, Cu: 0.92-11.0, Fe: 8.01-17.6, Mn: 1.46-2.20, Ni: 2.69-3.55, Pb: 1.83-2.63, Zn: 9.80-17.0 in ppm for muscles; Co: 2.14-3.99, Cr: 0.20-0.58, Cu: 1.32-22.6, Fe: 52.2-140, Mn: 13.1-20.3, Ni: 7.85-13.6, Pb: 2.75-6.28, Zn: 37.5-80.8 in ppm for gills. Additionally, daily and weekly intakes were estimated for muscle tissue. Because these values were markedly below the limits recommended by different international authorities, it may be said that consumption of these species from the Batlama stream in Giresun Coast is not a problem on human.

Abstract River ecosystems are vulnerable to heavy metal pollution. Fish samples are considered as one of the most indicative factors, in fresh water systems, for the estimation of trace metals pollution potential since they are the final chain of aquatic web. The objective of the present study is to evaluate the concentration of some toxic elements (As, Hg, Pb, Cd and Ni) in edible part of three wild fresh water fish species (zander (Sander lucioperca), wels catfish (Silurus glanis) and European carp (Cyprinus Carpio)) caught from Bulgarian part of Danube river collected during 2010. The Danube River is the European Union's longest and the continent's second longest river that passes through or touches the borders of ten countries. It has a great importance in regard to biodiversity, economics and transportation. The elements (As, Pb, Cd and Ni) were assayed using Perkin Elmer Zeeman 3030 electrothermal atomic absorption spectrometer with an HGA-600 atomizer. Determination of Hg was performed using Milestone Direct Mercury Analyzer DMA-80. The results were expressed as μg/g dry weight. The order of heavy metal accumulation in the edible part of zander is As>Hg>Pb> Ni> Cd while the other two fish species show a different metal accumulation Hg > As >Pb> Ni > Cd. In all heavy metals, the accumulation of mercuric and arsenic proportion was significantly high in all three fish types.

ABSTRACT This research has been conducted to determine the heavy metal (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) accumulation in the fish species Carp (Cyprinus carpio Linneaus, 1758) and Fatty fish (Phoxinellus anatolicus Hanko, 1924) taken from Suğla Lake, which is one of the most important water sources of Konya. In this research, conducted in 2009-2010, the heavy metal accumulation was examined in the time span of one year seasonally. And it has been concluded at the end of the research that the heavy metal accumulations show statistical dramatic differences between the seasons (p<0,05).
