Abstract
Phytoextraction of heavy metals from fly ash (FA) contaminated soil was evaluated using Phaseolus vulgaris var. T55. The results showed that electrical conductivity (EC), cation exchange capacity (CEC), organic carbon (OC) and organic matter (OM) of different amendments decreased with the addition of FA in the soil. The level of diethylene triaminepenta acetic acid (DTPA) extractable metals increased with increase in FA amendments up to 25%. However, Cr was found below detection limit in both the amendments. The metal accumulation in the plant tissues was found in the order of Fe > Zn > Mn > Co > Ni > Pb > Cu > Cd at 25% FA. Accumulation of Fe, Mn, Ni, Cu and Co was found more in the roots while Zn, Pb and Cd were more in the aerial parts.
