Study of Heavy Metals Concentration (Fe, Pb And Ar ) and Risk Assessment in Anchovies Fishes by Atomic Absorption Spectroscopy in the Persian Gulf and Oman Sea

The current research, in winter of 2018, was done in order to determine the concentration of heavy metals of Lead, Iron and Arsenic in Anchovies fishes in Persian Gulf and Oman Sea. After sampling and biometry the aquatic (60 samples) were transferred to laboratory for measuring the concentration of heavy metals in fresh and dried types. Measuring the metals in fish body was done by using of Atomic Absorption Spectroscopy (AAS). Data analyzing was done by using of SPSS software (version 24). For comparing the concentration of considered heavy metals was done by t-test method. The results of this research show that there is positive and significant correlation in under study with regions, also dried and fresh types, so that, concentration of Lead not detected in any type but in another metals concentration had different in each regions (P<0.05). Also, by comparing the average concentration of metals found in the body of the species with the reference dose (RfD) of the EPA organization, only the concentration of Arsenic metal in the dried types of the Oman Sea and the Persian Gulf regions was higher than the limit and the concentrations of Lead and Iron metals were lower than the specified value.Also the result of THQ and HI for a 70 kg person shows that, the Potential Danger of Lead, and Iron in all studied samples, was less than one, that shows the daily absorption of these metals by consumers is less than which has harmful effects on their health during their lifetime. But for dried specimens of the studied regions, THQ and HI for Arsenic metal was more than one, indicating that there is a risk of food intake in this amount.
