ABSTRACT
The aim of present research was to assess the usefulness of Virgina mallow Sida Hermaphrodita to phytoremediation of sorption subsoil contaminated with pesticides. Studies upon purification of sorption material consisting of a soil and sewage sludge were conducted under pot experiment conditions. The vegetation season lasted since spring until late autumn 2015. After acclimatization, the mixture of chloroorganic pesticides was added into experimental pots. After harvest, it was found that pesticide contents in sorption subsoil (from 0.3588 to 0.3991 mg kg DM) were much higher than in control soil (from 0.1600 to 0.2170 mg kg DM). The achieved results initially indicate that Virginia mallow can be used for reclamation of soils contaminated with pesticides, particularly for vitality prolongation of sorption barrier around the pesticide burial area. In the future, it would allow for applying the sorption screen around pesticide burial area, which reduces pesticide migration into the environment, and grown energetic plants – through phytoremediation – would prolong the sorbent vitality and remove pesticides from above ground parts by means of combustion.
