INFLUENCE OF COPPER OXIDE (II) NANOPARTICLES AND CU ION ON CHOLINESTERASE ACTIVITY OF HEMOLIMPH MUSSELS CRENOMYTILUS GRAYANUS (DUNKER, 1853) (BIVALVIA: MYTILIDAE) IN THE CONDITIONS OF A LABORATORY EXPERIMENT

Abstract

The influence of the content of copper oxide nanoparticles (NP CuO) and Cu2+ ions in the medium on their accumulation in the hemolymph of the mussel Crenomytilus grayanus is studied. The effect of copper oxide nanoparticles and metal ion (Cu2+) on cholinesterase activity in hemolymph of mussels is estimated. Multidirectional effects of CuO and Cu2 + nanoparticles on the copper content and cholinesterase activity in hemolymph are demonstrated. At the initial stage of the experiment, cholinesterase activity is shown to decrease in the case of the ionic form of copper, and in the case of copper nanoparticles, the activity increases. At the final stage of the experiment, an opposite situation for the considered forms of copper is observed.
