Survey heavy metals concentration (Cu, Zn and Ni) of muscle tissue of Litoppenaeus vannamei in farms of Bushehr province
Heavy metals pollution directly has a negative effect on marine aquaculture such as shrimp culture. Heavy metals accumulated in the shrimp can be transported to humans through food chain. In this study, concentration of heavy metals (Cu, Zn and Ni) in muscle tissue of western white leg Shrimp (Litopenaeus vannamei) in farms of Rig, Helle and Delvar sites of Bushehr province was determined. Heavy metals concentration was measured by atomic absorption. Results showed that there was a significant difference between Zn and Ni concentration of muscle shrimp in Rig, Helle and Delvar sites. The highest concentration of copper in Delvar, zinc in Rig and nickel in Heleh was observed 20.12±1.28, 56.12±9.33 and 9.10±0.87 (μg/g DW) respectively. The comparison results of metal concentrations in muscle tissue of shrimp with FDA, WHO and FAO standards showed that the nickel content in muscle tissue is higher than the permissible level for human consumption and requires further monitoring.
