In this study accumulation levels of Fe, Cu, Zn, Mn, Al, Sr, Cr, Pb, Cd, Hg was determined in water, sediment and some carp (Cyprinus carpio) tissue samples of Karacaoren-II Dam Lake between April 2009 – March 2010. Totally 24 carp have been caught and investigated seasonally. Heavy metal analysis were carried out by using ICP-OES. According to the findings; pH value varied between 7.42-8.02. In water; Cr, Cd and Hg values were below the detection limit in all seasons. Fe, Zn, Al and Sr were present almost in the whole seasons while Sr level was highest. In sediment; Fe, Zn, Mn, Al, Sr and Cr were present in all seasons while Fe was highest. Cu, Cd and Hg were below detection limit in all seasons while Pb below the detection limit in Spring. In carp tissues; Fe and Zn were determined in all seasons in whole tissues, however Cu only in Spring in liver tissues. Fe level reached highest among all metal concentrations. Cr, Cd and Hg were not determined in any tissues in all seasons. Metal concentrations were higher in the liver and gill than muscle. |
