Trace metals (Cu, Cd, Zn, and Pb) in the liver and the kidney of Acipenser persicus with relation to their concentrations in the surficial sediments of the west coast of the southern Caspian Sea
چكيده لاتين :
This study was carried out to find any relative concentrations of the trace
metals (Cu, Cd, Zn and Pb) in the liver and the kidney of Acipenser persicus and in
the surficial sediments of the west coast of The Southern Caspian Sea. Twenty five
samples of the Acipenser persicus (Persian sturgeon) and ten samples of the
sediments were taken from five fishing stations in autumn 2001. The tissues were
digested by wet method and the sediments were digested by dry method. Every
digested sample was separately analysed by AAS (Atomic Absorption
Spectroscopy), Recovery, mean, ANOVA, correlation coefficient and hierarchical
cluster analysis were calculated. It was concluded that the concentrations of the
studied trace metals (Cu, Cd, Zn and Pb) were at the standard level and there was a
positive correlation coefficient between the kidney and the liver in the concentrations
of Cd and Pb.
