ABSTRACT
Vefiver grass (Vetiveria zizanioides) has strong and dense roof system and is a potential phytoremediator plant since it can tolerate a wide range of climatic conditions and grow well in soils con taminafed with heavy metals. Soil was artificially contaminated by lead (20 mgl-1) during field trials. Four concentration of EDTA (Ethylene diamine tetra acetic acid-disodium salt) solution i.e. 0, 3, Sand 10 mmol kg-1 were added to soil prior to harvesting, to study the influence of ED TA solution on phytosfabilization by vetiver grass. Results sho wed that the concentration of lead in roots of vetiveris significantly increased alter ED TA solution (5 mmol kg-1) application. However, high concentration ofED TA (10 mmol kg-1) does not show such significanf increase. The toxicity of highly contaminating metal did not affect the growth of vetiver grass significantly but a slight decrease in parameters studied was noticed. No stress symptoms were observed in vetiver plants. Results of present study reveal that vetiver could be considered as a potential phytoremediator for lead contaminated site.
