The research objective was studying of reaction of standard test organisms to biogenous nanoparticles of ferrihydrate. The research of properties of biogenous nanoparticles of ferrihydrate concerning a number of live organisms was conducted with application of standard test objects (invertebrates, monocelled alga, two-submultiple plant) and standard techniques. As test re-actions to the effect of biogenous nanoparticles of ferri-hydrate the survival of water fleas, the growth of culture of hlorella, germination of seeds of a garden cress were estimated. Initial concentration of suspension of bioge-nous nanoparticles of ferrihydrate made 0.996 g/dm ³. The diameter of nanoparticles was equal to 2-10 na-nometers. For carrying out toxicological analysis with use as test object of the water flea (Daphnia magna Straus) measurement technique of quantity of Daphnia magna Straus was applied to determination of toxicity drinking, fresh natural and sewage, water extracts from the soil, soils, sewage, production wastes and consump-tion by method of direct account. Studying the reaction of seaweed in the presence of biogenous nanoparticles was conducted on the example of hlorella (Chlorella vulgaris Beijer). The change of the number of cells on the optical density of culture was analyzed. The exposi-tion of the experiment made 22 hours. Distilled water was used as control. At such test object as a garden cress (Lepidium sativum L.), at the detection of toxicity of environment viability of seeds were considered, com-paring control and experimental options. Couched grade garden cress seeds Entertainment with exhibiting in a damp chamber within 5 days. In all options of the exper-iment three frequencies to each test organism were applied. It was established that nanoparticles do not make toxic impact on the survival of Daphnia magna, growth Chlorella vulgaris and viability of Lepidium sa-tivum.
