Abstract :
The aim of this study was to determine the concentrations of heavy metals Nickel and Cadmium in muscle tissues of Liza klunzingeri in Bushehr seaport during 2017. 30 samples of Liza klunzingeri were caught completely at random from Bushehr seaport by the area local fishermen should be omitted. After biometry of the samples, the muscle tissues of the samples were separated and chemical digestion of the samples was done by MOOPAM, then Nickel and Cadmium accumulation levels in tissues were measured using Graphite furnace atomic absorption instrument (VARIAN AA 100). Based on the obtained results the mean concentrations of Nickel and Cadmium in muscle tissues of Liza klunzingeri were calculated (6.638 ± 0.611) and (3.201 ± 0.292) mg/kg dry weight respectively. The results of this study revealed that the Nickel and Cadmium metals concentration in edible tissues (muscle) of Liza klunzingeri in study station are more than the levels permitted within the standards of WHO, FAO, NHMRC and UK(MAFF).
