Abstract
Phytoremediation is a promising technology for cleaning soil and water from toxic heavy metals. It is known that humic substances possess the capability of increasing the intensity of metal absorption by plants. In this connection, the effect of humic preparation from peat on the accumulation of lead by wheat plants was studied for lead nitrate concentrations increasing up to 500 μM / l in a model vegetation experiment in aquatic culture. A significant increase in the accumulation of lead in wheat shoots (above 1000 mg / kg) was established under the progressive action of lead nitrate in comparison with the pronounced effect, indicating the possibility of using wheat as a phytoremediant. Humic preparation strengthened the phytoremediation properties of wheat, estimated by the coefficient of biological absorption: up to 5.4 times with a pronounced effect and up to 2.6 times at a gradual level, which confirms the possibility of using humic substances as phytoextraction effector.
