Background: Considering the industrial and agricultural developments and improving human life in recent decades, the use of heavy metals in various fields is unavoidable. Also, the use of aquatic resources, especially fish meal as protein sources in part due to increasing population has increased. The aim of this study was to determine the heavy metals such as Lead, Cadmium and Mercury in white and Ghezelalla fish consumed in the province of Lorestan.

Materials and Methods: In this study, 40 samples were selected to determine the heavy metals (Lead, Cadmium and Mercury) after digestion by the Association of Official Analytical Chemists methods. Mercury levels in fish were determined by hydride generation atomic absorption spectrophotometery, while Cadmium and Lead levels by graphite atomic absorption spectrophotometery model Perkin Elmer.

Results: The results showed that the mean concentrations of Lead in fish were 2.93±0.55, 1.65 ppm±0.5, cadmium 1.15±0.47, 1.36±0.54 ppm and mercury 0.68±0.4, 0.95±0.2 ppm.

Conclusion: The average concentration of metals is higher than the standard rate of World Health Organization, the National Health and Medical Research Association of Australia, and the department of Agriculture - Fisheries and Food in UK.

Keywords: Ghezelalla, White fish, Lead, Cadmium, Mercury
