Abstract :
Heavy metals may accumulate in aquatic animals’ organs and tissues such as liver, kidney, gills and muscles.As fsh muscle is important in human nutrition, its health is important. Metals are considered as non degradablesubstance and one of major environmental pollutants, those negative effects may cause cytotoxicity, mutation andcarcinogenicity in animals. The risk of heavy metal toxicities differs in each water resource and animal species.Toxicity of these metals is higher in soft waters compare with hard waters.In this present study, 44 samples of Psettodes erumei fsh were randomly collected from Boushehr’s waters. Then100 grams of pectoral muscle of each fsh dissected and got ready for atomic absorbtion measurement. The resultsof four heavy metals Lead, Cadmium, Zinc and Chromium were registered in microgram per kilogram (ppb). Inpresent research, the maximum amount of metal was related to Zinc (138.5 ppb) and the minimums to Chromium(30 ppb). In the results, the highest / lowest levels for each metals are: Lead 0.124 / 0.037, Cadmium 0.090 / 0.019,Zinc 0.208 / 0.034 and Chromium 0.054 / 0.013 ppm in muscles and all were totally in safe limits of World HealthOrganization limits.
