Use of herbaceous vegetation for soil bioremediation of heavy metals

Over the last decades the use of herbaceous vegetation for soil remediation of heavy metals, called phytoremediation, has gained considerable importance because this technique is permanent and environmental friendly, has low cost and does not aesthetically disrupt the landscape. Plant species able to hyperaccumulate and tolerate heavy metals that have high growth rate and biomass production and possess an extensive root system are considered as suitable phytoremediators. Aim of this paper was to present the most significant phytoremediation techniques using herbaceous vegetation.
