RESUMO

Biomarkers of the oxidative stress in the digestive gland and gills of the bivalve mollusk Colletopterum piscinale from the pond situated within the agricultural area (A) after the 14-days transplantation into the laboratory aquarium (L) or into the pond situated within the urbanized area (U) in summer and autumn have been compared. According to the Mn- and Cu, Zn-super dismutases’ activity, reduced glutathione content, lipid peroxidation rate and protein oxidative modifications rate, Index of oxidative stress calculation and data of the dispersion ANOVA/MANOVA analysis, depression of the anti oxidative protection was observed in the mollusks from the agricultural area in comparison with transplanted specimens. Particularly this was observed in summer, on the background of the water body chemical pollution. In the mollusks transplanted into the pond rate of the lipids and proteins oxidative destruction and metallothioneins content in the digestive gland was higher than those in the laboratory group. Positive correlation between iron content and protein oxidative modification in the gills, as well as between manganese content and system of the anti oxidative protection activity in the digestive gland has been stated. Most studied parameters had seasonal changes similar for the different mollusks' tissues and groups.
