This study aimed to investigate the concentration of some heavy metals in three fish species with high consumption in Shif Island, Bushehr Province, and calculation of the estimated daily intake (EDI), estimated weekly intake (EWI), Target Hazard Quotients (THQ) and hazarded index (HI). Three species viz. Euryglossaorientalis, Argyrops spinifer, and Sillago sihama were collected from the Bushehr coastal water using fishing boat. After the transfer of samples to the laboratory, the heavy metals were extracted and analyzed using Atomic Absorption Spectrophotometer (AAS). Based on the results, the average concentrations of Fe, Zn, Cu, Mn and Ni in E. orientalis were 10.02, 8.33, 1.18, 0.80, and 0.86 mg/kg, in A. spinifer 7.25, 5.75, 0.74, 0.43, and 0.37 mg/kg,  and in S. sihama  6.20 , 8.27, 0.60, 0.47, and 1.28 mg/kg, respectively. Daily and weekly intake values in all three studied species in the group of children were higher than the adult group. The highest and lowest daily and weekly intake rates were observed for Fe in the E. orientalis and Cu in A. spinifer. The Target hazard quotient (THQ) and Hazard index (HI) for both adults and children showed less than 1. Also, the comparison of metal concentrations showed that the concentration of Mn in all three species and Ni in E. orientalis and S. sihama were higher than the WHO standard.
