Bioindication of the environmental state of marine areas with the use of fish biomarkers

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.
