Rudnitska L. Еcotoxicological assessment agrochemicals obtained nanotechnology

The features of the structure, size and value of the chemical nanoparticles that are part nanoagrochemicals. The expediency of consideration of physical and chemical properties of nanoparticles, including their size, which determine toxicity. Study of nanoagrochemical effect on biological systems at various levels of the organization, taking into account physical and chemical properties of nanoparticles that make up their composition was done. The most sensitive bioassays for evaluating toxicity nanoagrochemicals: indicators characterizing cell division meristematic tissue (Allium cepa L.); morphometric parameters of higher plants (biotest cress-salad); indicators of activity of soil bacteria-microorganisms participating in nitrogen cycle and determine the level of capacity nitryfikatsiynoyi soil; characteristics of the populations of aquatic organisms (crustacean Ceriodaphnia affinis Lilljeborg) were determined. The current system of performance evaluation that takes into consideration characteristics of agrochemicals, which include nanoparticle were Improved. Specifically, supplemented by indicators cytotoxicity characteristics of size and shape of nanoparticles that will objectively carry out their environmental hazard prediction. It was foind that in terms of impact on biota water, soil and terrestrial ecosystems higher level of toxicity was characterized by preparation Avatar-1 regarding drug Nano-Gro, depended not only on the dose of use and overall chemical composition, but also the size and shape (geometry) nanoparticles who were in their composition.
