Trace elements accumulation in edible tissues of five sturgeon species from the Caspian Sea.
This study is focused on twenty trace elements (Ag, Ba, Bi, Cd, Co, Cr, Cs, Cu, Ga, In, Mn, Mo, Pb, Rb, Sb, Sn, Sr, Ti, V, Zn) accumulation in muscles of five sturgeon species (Acipenser guldenstaedti, A. persicus, A. nudiventris, A. stellatus and Huso huso) from the southern part of the Caspian Sea. Moreover the relationships between some biological characteristics and the levels of the selected elements as well as inter-elemental relationships were assessed. The samples (10 specimens for each the five species) were collected from two important sturgeon fishery zones located in the Iranian part of the Sea in 2002. Concentrations of the elements were determined using ICP-MS. Only in the case of Cs could significant differences between two selected sampling areas be detected. There were significant differences in levels of Co, Ga, Rb, Sn, Ti, Pb and Bi in muscles of the species. Only in the case of Cd weight related differences among the species were found. The significant length dependent relationships were observed for Ga and Ba. Patterns of elements accumulation were assessed by statistical methods and compared to the other researches. In all the cases, the amounts of toxic trace elements (Cd, Cu, Pb and Zn) were markedly below the international guidelines for human consumption.
