NATURAL NANOMATERIALS ? ZEOLITES, AS MELIORANTS OF PETROL-POLLUTED SOILS

Pollution of the soil by petrol is accompanied with a strong negative effect on plants due to changes in its physical-chemical properties, mainly due to an increase in hydrophobicity and the filling of soil capillaries with petrol and the direct toxic effect of petroleum hydrocarbons (phyto toxicity). Zeolite (clinoptilolite), is an ecologically safe effective ameliorant for the reclamation and rehabilitation of polluted soil. The article presents data on the effect of various concentrations of petrol in the soil on the growth and development of wheat using a zeolite meliorant. It is shown that the introduction of zeolite into petrol-contaminated soil has a significant melioration effect and improves the development of the test culture.
