| Abstract: | The study is focused on the effect of the concentrations of toxic elements Zn, Cu, As, Pb, Hg, and Cd in the muscles of six
species of Black-Sea fish on the concentrations of modified forms of proteins and medium-molecular peptides in fish serum.
Correlation analysis established that the effect of toxic elements on the concentration of modified forms of proteins decreases
in the series Zn + Pb > As > Hg > Cu > Cd and that for medium-molecular peptides decrease in the series Pb > Cu > Zn > Hg
> As + Cd. The possible use of the concentration of modified forms of proteins and medium-molecular peptides in fish blood
as biomarkers for assessing their state and the effect of habitat on them. |
