| dc.description.abstract | Phytoextraction involves the absorption of contaminants by roots followed by translocation and accumulation in the aerial parts. It is mainly applied to metals (Cd, Ni, Cu, Zn, Pb) but can also be used for other elements (Se, As) and organic compounds. Experiments were carried out with 24 polyethylene pots each containing 7 kg of sandy loam soil mixed with 50 ml of crude oil. Twelve containers contained the crude oil-polluted soil while the remaining twelve containers contained the Control soil. Seeds of Amaranthus hybridus L., Tithonia diversifolia, Abelmoschus esculentus L. and Zea mays were sown in polyethylene containers containing 7 kg of contaminated or Control soil. The seeds were sown after two weeks of spiking the soil with crude oil. After two months, plants were harvested, separated into roots and shoots. Five heavy metals, namely Copper, Lead, Chromium, Cadmium and Nickel were evaluated. On the basis of the results obtained, the plants were classified as accumulators, hyperaccumulators, indicators or excluders. The results showed that Z. mays has the ability to accumulate Cu, stabilize Pb and Ni in crude oil-polluted soils. Z. mays is an excluder of Cr and Cd in crude oil-polluted soil. Z. mays showed suitability for Cr accumulation in Control soil with TF > 1 but less suitable for Pb extraction in Control soil with BCF, TF and BAF < 1. A. esculentus is suitable for phytoextraction of Cu, Cr and Pb, phytostablize Ni and Cd in Control soil. A. esculentus proved suitable for Cd phytoextraction in crude oil-polluted soil but less suitable for Ni extraction in crude oil-polluted soil. A. hybridus is an accumulator of Cu, Cd and Pb, stabilizer of Cr and Ni of crude oil-polluted and an excluder for Cr and Ni for Control soil. T. diversifolia was the most efficient in remediating Cu and Cd in crude oil-polluted soil. A. esculentus had the highest remediation factor in both crude oil-polluted (0.0475%) and Control soil (0.048%). A. esculentus was the most efficient at remediating Cd in crude oil-polluted soil, while T. diversifolia was the most efficient in the remediation of Cd in Control soil. | |
