Detoxification ability of magnetite nanoparticles in pesticide contaminated soil

Abstract

In the experiment, we studied the effect of two compounds of Fe3O4 magnetite NPs with a size of 8-20 nm on the growth of wheat seedlings. One of the compounds (sample 2) contained a PVP stabilizer; the other did not. The wheat seeds were germinated on soil plates; the soil used in the experiments was contaminated with pesticides for a long time; it was taken in the territory of a former warehouse of pesticides and fertilizers in Singera, Moldova. Colloidal solutions of Fe3O4 magnetite NPs (samples 1 and 2) in concentrations of 10, 50, and 100 mg/kg of dry soil were used.
