Environmental aspects of the use of ultrafine particles SiO2 (as exemplified by Solanum tuberosum)

Abstract

Abstract The interest in the use of ultrafine particles in crop production and agricultural practice is associated with the unique properties of ultrafine particles (UFP). At the same time, it is obvious that artificial nanoobjects can have toxic properties. Therefore, for further development of nanotechnologies, a clearer understanding of both the properties of nanomaterials themselves and the mechanisms of their interaction is needed. The article presents studies on the effect of ultrafine particles of silicon dioxide on plants Solánum tuberósum. According to the results of research nano-silica at a concentration of 0.21 and 0.36 g/kg had a statistically significant effect on the number of cell integrity (a decrease to 17.1 % was observed). It was revealed that after processing potato tubers with UFP silicon oxide at a concentrations of 0.09 and 0.18 g/kg, they had a significant influence on the activity of peroxidase. The results of the studies revealed the toxicity of UFP SiO2 at a maximum dilution of 0.36 g / kg, which confirmed a decrease in the intensity of the luminosity peaks of DNA a temporally calculated linear profile. Therefore, assessing the impact of SiO2 use is of great importance for understanding the long-term environmental impact of UFP.
