Abstract :
This study was carried out to detect the concentration of heavy metals (As, Se, V) in the muscle, gill and hepatopancreas tissues of female and male sexes of Litopenaeus vannamei in Choebdeh shrimp culture (Abadan) at fall 2015. Sampling was conducted with 4 repeats at 3 pounds by net. After separation of tissues, samples were digested by acid digestion with nitric, percloric acid and hydrogen peroxide. The analyses for the detection of heavy metals were carried out by flame atomic absorption spectrophotometer. The highest concentration of As in hepatopancreas was 5.32±0.008 mg kg (- 1) d.w. The highest concentration of Se related to gill (3.112±0.003mg kg (- 1) d.w.). The highest concentration of V related to hepatopancreas (2.106±0.014mg kg (1) d.w.). The alteration process of As and V in the selected tissues order hepatopancreas > gill > muscle. The alteration process is in the selected tissues order gill > hepatopancreas > muscle. Also significant differences (P<0.05) were recorded between the As, Se and V concentrations in all tissues. In this study, concentration of heavy metals in muscle, hepatopancreas and gills tissue in Choebdeh shrimp farms (Abadan) were lower than WHO standards.
