Abstract

Phytoremediation is a method that use plants which can remove or stabilize pollutants in the environment. The aim of the polluted area remediation is to return ecosystems into original condition. Phytoremediation is a green technology used for a wide range of pollutants as well as on various lands, low costs and reduced environment impacts. Energy crops are relatively new in this field of researches and insufficiently explored. However, the results so far show their potential in heavy metal removal. The aim of this research was to examine the available literature and determine the phytoremediation potential of cadmium, chromium, copper, lead, mercury, nickel and zinc from the soil using Arundo donax, Miscanthus x giganteus, Panicum virgatum, Pennisetum purpureum, Sida hermaphrodita and Sorghum x drummondii. According to the researches conditions, studied energy crops are reccomended in heavy metals phytoextraction, rhizofiltration, stabilization and accumulation. Still, those plants accumulate higher concentrations of heavy metals in the rhizosphere which makes them heavy metals excluders since heavy metals are not translocated into the plants' shoot system and favorable in the implementation of rhizofiltration as well.
