The spectral properties and metal content in metallothioneins (MTs) isoforms from the liver and gills of crucian carp Carassius auratus resided in clean (Z) and polluted (B) ponds after exposure of copper and manganese ions, as well as organochlorine and dithiocarbamate pesticides (each at two concentrations) during 14 days were compared. Differences between these characteristics of animals from two populations and their changes under exposure to disturbance factors, especially significant in group B due to decreased of metal-binding ability of MTs, especially in the gills were shown. By means of Canonical analysis the general features of UV spectra in fish under effect of natural complex pollution and the model action of pesticides were confirmed.
