Bioaccumulation of Zn, Cu and Mn in the Caviar and Muscle of Persian Sturgeon (Acipenser persicus) from the Caspian Sea, Iran

Concentrations of Zn, Cu and Mn were examined in caviar and muscle of the Persian sturgeon ( Acipenser persicus ) collected from coastal waters of south Caspian Sea during March and April, 2011. Mean Zn, Cu and Mn concentrations in caviar samples were 21.48, 2.05 and 1.66 μg g −1 wet weight basis, respectively. The mean Zn, Cu and Mn concentrations in muscle tissues were 7.49, 1.00 and 0.34 μg g −1 wet weight basis, respectively. The mean concentrations of Zn and Cu in caviar and muscle samples were under the permissible limits proposed by the United Kingdom’s Ministry of Agriculture, Fisheries and Food ( 2000 ).
