Cadmium concentrations in shrimp (Penaeus semisulcatus and Penaeus monodon) caught from the coastal areas in Southern Iran.
This study was undertaken to determine the concentration of cadmium in two shrimp species, namely, Penaeus semisulcatus and Penaeus monodon caught from the coastal areas in southern Iran. Cadmium concentration was determined by graphite furnace atomic absorption spectrophotometry in 91 shrimp samples after nitric acid/perchloric acid digestion. Accuracy of the analysis was checked by various methods including the use of reference material. The mean ± SD of cadmium concentrations in shrimp samples were 0.128 ± 0.144 (μg/g). The cadmium concentrations ranged from 0.010 to 0.96 μg/g of the muscle tissues of shrimp. Higher cadmium concentration in shrimp samples was found in summer (significant p < 0.05). The results show that the mean concentration of cadmium in shrimp is lower than the maximum allowed levels according to International standards, although the concentration of cadmium in only one sample was more than the amount recommended by Food and Agriculture Organization. Therefore, no risk to the consumer arises from the cadmium contents of the shrimp caught in these areas.
