Potential health risk assessment of some heavy metals (lead ,Nickel, Zink, Copper and Iron) in muscle of Silago Sihama in Qeshm, Khamir Port and Pol Port, Hormozgan

Abstract

The present study investigated the heavy metals accumulation (lead, nickel, zinc, iron, and copper) in the muscle of 180 Silver Sillago (S. sihama) from three regions of Hormozgan Province (Qeshm, Khamir Port, and Pol Port) during summer and winter. After biometrics samples were prepared using chemical digestion and the heavy metals (lead, nickel, zinc, iron, and copper) were measured using atomic absorption spectrometry. The results showed that the accumulation of lead, nickel, zinc, iron, and copper in muscle was significantly different in these three regions and also between the two seasons. The highest accumulation was observed in Qeshm in summer and winter. Moreover, the results showed that the accumulation of lead, nickel, zinc, iron, and copper was higher in summer compared to winter (in all three regions). The comparison of heavy metal accumulation in fish muscle with international standards showed that the accumulation of lead, nickel, zinc, copper, and iron were lower than FAO, WHO, and EPA standards. Food risk assessment indicated that there is no danger in the consumption of Sillago sihama with the current bioaccumulation in terms of the presence of lead, nickel, zinc, copper, and iron.
