The dynamics of the biochemical parameters of the external mucus of carp Cyprinus carpio L. exposed to 1 μM concentrations of heavy metal salts (CuSO₄·5H₂O Pb(NO₃)₂ and ZnSO₄·7H₂O) were studied. The biochemical parameters of external mucus (specific weight, pH, total protein, hemoglobin, ketones) were measured during exposure at 1, 3, 6, 24 h and regularly during a 21-day post-exposure period. Significant changes in hemoglobin and total protein concentrations were determined during the period of exposure to heavy metals and after it. Correlations of changes in biochemical parameters of mucus with the intensity of some parameters of sun activity and radio radiation flow were found during the post-exposure period. It was concluded that it is necessary to assess the possible complex effects of various origin and the magnitude of environmental factors on fish.
