Abstract

This research was carried to determine the concentration of heavy metals (Pb and Cd) in the muscle and liver tissues of  javelin grunter (Pomadasys kaakan) in the Hormuz Island waters in 2017. Fish samples were  collected from local fishermen catches. Samples were frozen and transferred to the laboratory for further analysis. A total of sixteen specimens  were biometrics and muscle and liver tissues were separated. Then concentration of heavy metals were determined following wet digestion using Flame Atomic Absorption Spectrophotometry. The results indicated that the average lead concentration in muscle and liver tissues are 0.141 mg/kg and 0.399 mg/kg respectively. The average cadmium in muscle and liver tissues are 0.055 mg/kg and 0.222 mg/kg respectively. These values were compared with the WHO, Food and Drug Administration, Nation Health and Medical Research Council and UK (MAFF) safety standards regarding the amount of the above mentioned heavy metals in fish tissues. According to the results, the average concentrations of cadmium and lead in muscle tissue proved to be lower than international standards. Therefore this species is healthy for eating by people in terms of health.
