Determination of some heavy metals by ICP-OES in edible parts of fish from Sapanca Lake and streams

Abstract

In this study, 20 fish taken from Sapanca Lake, Sakarya River and Western Black Sea (Karasu) in total and heavy metal accumulation (Cu, Fe abd Zn) in the muscles of 15 species was determined with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectometer) device. When the results were examined, Cu, Fe and Zn concentration was determined to be 2.60-5.31 mu g/g, 0.25-54.36 mu g/g and 13.66-47.11 mu g/g respectively in fish samples. In addition, the same procedures were applied with the standard reference material DORM-3 reference material (Fish Protein Certified Reference Material for Trace Metals) to determine the accuracy of the method. As a result, it has been determined that the amount of heavy metals contained in the analyzed fish samples is below the limit values provided by the Turkish Food Codex, Food and Agriculture Organization and World Health Organization and therefore consumption of these does not constitute a threat to health.
