Determination of heavy metal (Nickel and Cadmium) concentrations in muscle and liver tissues of (Pomadasys kaakan) in Bushehr seaport

The aim of this study was to determine the concentrations of heavy metals Nickel and Cadmium in muscle and liver tissues of Pomadasys kaakan in Bushehr seaport during 2015. 20 samples of Pomadasys kaakan were caught completely at random from Bushehr seaport by the area local fishermen should be omitted. After biometry of the samples, the muscle and liver 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 in muscle and liver tissues of Pomadasys kaakan were calculated 0.284 ± 0.074 and 0.344 ± 0.081 mg/kg dry weight respectively and showed that there were no significant differences (P>0.05). Moreover, based on the obtained results the mean concentrations of Cadmium in muscle and liver tissues of Pomadasys kaakan were calculated 0.118 ± 0.011 and 0.132 ± 0.021 mg/kg dry weight respectively and showed that there were significant differences (P
