Peculiarities of ecotoxicological assessment nanoagrochemicals used in crop production

The article presents the results of studying the toxic effect of nanoagrochemicals on the processes of a plant's cell division, growth and development of plants at the early stages of ontogeny. It can be assume that the toxic effect of nanoagrochemicals depends on the size and structure of the nanoparticles, which are included in their composition: the toxic effect is stronger, the smaller the size of the nanoparticles is; nanocomposites of crystal structure are more toxic compared to nanocomposites of amorphous structure. Nanoagrochemicals ecotoxicological risk assessment should not be based only on the study of the dependence “dose-effect” on the level of the organism and population; it should include the research of the toxic process, starting from the level of the cell and its organelles.
