摘要

In recent years, with the development of the global industrialization, the content of heavy metals in the soil caused by industrial activities hasgradually increased, resulting in environmental deterioration. There is a need to provide viable option that is economical, environmental friendly andsustainable for clean-up of environmental contamination such as phytoremediation. Series of studies conducted in the past on heavy metals contentin soil around Ajaokuta Steel Company Limited (ASCL) without considering the remediation technologies of such contents. This study primarilyassessed the phytoremedial potential of indigenous flora around Ajaokuta Steel Company Limited Ajaokuta, Kogi State, Nigeria. To achieve this,top and sub soil samples along with control were collected around the vicinity of ASCL for heavy metals analysis. Four different indigenous plants(Imperata cylindrica (Spear grass or cotton wool grass), Sida acuta (Wire weed), Helianthus annuus (Sunflower) and Chromoleana odarata (Siamweed) grown within the vicinity of the ASCL were randomly collected for heavy metals analysis. The samples were digested and analyzed usingAtomic Absorption Spectrophotometer (AAS) (Perkin Elmer? Analyst 100 model). The data obtained were analyzed using SPSS 20 for descriptiveand inferential statistics. The metal transfer factors were also determined. The results obtained revealed that the potential of remediating Leadby C. odarata was high compared to other plant species which uptake 10.33 mg/kg, 20.11 mg/kg, and 25.32 mg/kg in the leaves, stem androot respectively. The bioaccumulation level of Lead in C. odarata and H. annus were recorded to be 0.91 mg/kg and 0.71 mg/kg respectivelywhich indicated highest bioaccumulation factor. Unlike the bioaccumulation factors, the translocation factors were high in all the heavy metalsinvestigated. The study revealed that C. odarata, I. cylindrica and S. acuta are good accumulators of heavy metals and they should therefore beencouraged to be cultivated. The plant species may be regarded as hyperaccumulators, which is characterized by their ability to accumulate highquantities of metals in their tissues.

Odarata分别与其他植物物种相比。分别摄取10.33mg / kg，20.11mg / kg和25.32mg / kg的其他植物种类。C. Odarata和H. Annus中的铅的生物积累水平分别记录为0.91mg / kg和0.71 mg / kg，指出最高的生物累积因子。与生物累积因素不同，易位因子在所有浓度中都很高y metalesinvestigated。该研究表明，C. Odarata，I。Cylindrica和S.Acuta是重金属的良好蓄能器，因此应该受到培养。植物物种可被视为高累积仪，其特征在于它们在组织中积聚金属的高态性的能力。
