Abstract
Phytoremediation is one of the environmental rehabilitation techniques that take advantage of plant physiology and metabolism. In this study, a greenhouse experiment was carried out in order to examine the applicability of plants for the remediation of lead (Pb) contaminated soil. Buckwheat (Fagopyrum esculentum) was the best plant for Pb phytoextraction in the first cultivation. Rye(Secale celeale), oat(Avena sativa) and phacelia (Phacelia campanularia) was a useful Pb accumlator for autumn sowing. In effect of leachate reduction by vegetation, the total amount of leachate for vegetation cultivation period was less than the control (no vegetation). As a result,it was concluded that vegetative coverage reduces downward water movement in the profile of Pb contaminated soil.
