This study evaluated the potential of Ipomoea asarifolia to remediate lead (Pb) polluted soils. The plant was grown on soils amended with varying levels of Pb in different polythene pots and atomic absorption spectrophotometry (AAS) was used to analyse the accumulation of Pb in roots, stems and leaves of the plant within three harvesting phases of the study period. The results revealed that the plant accumulated a total biomass of 308.13mg, 392.07mg and 482.21mg Pb from 328.24 ± 2.33mg/kg, 433.03 ± 0.59mg/kg and 537.25 ± 0.92mg/kg Pb-polluted soils respectively. The Transportation Indices for Pb translocation to the different parts pf the plant showed that I. asarifolia has both RTI and STI of less than 1 (TI |
