| This study was carried out to comparison heavy metals accumulation (Zn), (Cu), (Cd) and (Pb) in muscle and shell of Litopenaeusvannamei and Metapenaeusaffinis in 2013. Thus, 6 kg M. affinis from coast of Bahrekan and 6 kg L. vannamei collected from site of Delvar in Bushehr Province. Preparation of samples was doneand digested using nitric acid and Zn using flame system and Cu, Cd and Pbusing graphite oven of absorption spectrophotometer were measured. Results of all heavy metals in muscle and shell in M. affiniswerehigher significantly (P<0.05)than inL. vannamei unlike toPb(P>0.05). Metals in shell of two specieswere higher than muscle, thus showed significant difference(P<0.05) except forPb (P>0.05). Results showed higher mean(± SD) concentrations of Zn were observed in shell and muscle of M. affinis (44.6±15.67 and 38.6±12.85 mg/kg) and in L. vannamei (40.6±13.66 and 34±9.52 mg/kg) and lower concentrations of Cd were observed. Sequence of concentration of heavy metals in two species and their organs followedthe order of Zn> Cu>Pb> Cd. |
