ABSTRACT. It was determined the research results that allow solving scientific and practical problems in the study of influence, accumulation and safety of nanoaquacitrates in hydroecosystems and hydrobionts. The model investigations with experimental hydrobionts Cyprinus carpio L in the water with different concentration of nanoaquacitrates have been carried out. It has experimentally been analyzed that nanoaquacitrates relatively quickly yield to elimination due to absorption, as well as precipitation, thus transmutating into insoluble, biologically less active substances. The accumulation of nanoaquacitrates in animals depended on the base metal and its concentration in water. An increase of zinc and cooper content in the animal liver and gills has been found. At the same time, the content of nanoaquacitrates in skin and muscles of the fish has not differed significantly between all experimental groups of hydrobionts, including the control group. The absence of accumulation effect of the copper and zinc nanoaquacitrate at the concentration of 0.01 mg/L has been indicated. Thus, the established patterns of nanoaquacitrate influence on the hydrobionts and the criteria of their environmental safety have been developed. They lay the foundation for the practical implementation of these substances in anti-epizootic measures in aquaculture and agricultural production in general.
