EFFECTS OF NANOPARTICLES AND IONS COPPER ON THE FORMATION PRODUCTS OF LIPID PEROXIDATION IN ORGANS MUSSELS CRENOMYTILUS GRAYANUS (DUNKER, 1853) (BIVALVIA: MYTILIDAE) UNDER LABORATORY CONDITIONS

A comparative evaluation is performed of the effect of CuO (CuO NPs; 20 mkg/l) and Cu (12 mkg/l) nanoparticles on the formation of lipid peroxidation products (malondialdehyde (MDA), 4-hydrox-2,3-inonenal (4-HNE)) in gills of a mussel in a laboratory experiment. The results demonstrate low bioavailability of CuO NPs that we have used for the mussels. Moreover, in gills of molluscs, in the experiment with particles and copper ions we have observed changes in the content of MDA and 4-HNE as compared to those in the control group. Taking into account the fact that there is no considerable accumulation of Cu in the group with CuO NPs, the manifestation of its toxicity is suggested to be indirect.
