Abstract
The article presents the data of experimental studies to identify the effect of biogenic cobalt-doped ferrihydrite nanoparticles on the growth of a model test plant Lemna minor. The test object was exposed for 7 days in a Steinberg medium with the addition of nanoparticles suspension (1.5 mg/l, 4.5 mg/l, and 15.0 mg/l). The analysis of the experimental data showed a suppressive effect of biogenic cobalt-doped ferrihydrite nanoparticles on the number of fronds and the growth rate of Lemna minor at a concentration of 15.0 mg/l. The indicators of root growth (number, length, weight) were similar to the control ones. The obtained data confirm the available data about the negative impact of elements in the form of nanomaterials at high concentrations and require further studies.
