Abstract:
The aim of this study was to evaluate potential of ferrite nanoparticle to remediate the soil, long-term exposed to obsolete pesticides (HCH, DDT and their metabolites).
The soil from orchard situated in Călăraș district, Republic of Moldova, was
contaminated with obsolete organochlorine pesticides. At the set up of the experiment in anoxic conditions the soil was amended with colloidal aqueous solution of Fe 3O4/PVP nanoparticles. The determination of pesticide residues in soil was confirmed by gas chromatography with mass spectrometry GC/MS multiresidue method. As a result, HCH, represented mostly by persistent beta-HCH isomer, completely disappeared. The study was supported by the Project «Innovative biotechnological solutions for agriculture, medicine and environment» no. 020101.
