The Possible Effectiveness of Eleusine indica L. as a Phytoremedaiting Agent of Spent Engine Oil on Contaminated Soil.
This study evaluated the possible effectiveness and mechanisms employed by Eleusine indica L. as a phytoremediating agent of spent oil on contaminated soil. This was by monitoring the influence of the oil on the anatomy and some growth parameters of the plant found around auto-mechanic sheds and waste areas in Lagos, Nigeria. Chemical analysis of the plant and soil were also carried out to determine the Total Hydrocarbon Content (THC) and Lead content at the start and end of the experiment. Uniform tillers of the plant were grown in equal volumes of garden soil treated with 1000ml, 1500ml, 2000ml, 2500ml and 3000ml of spent oil except the control. After six weeks, considerable reduction in THT and Lead content were observed in the treated soil while there was also a considerable amount of Lead in the plant. The study established that although E. indica grew under stress,as indicated by the low RGR, Shoot biomass and Chlorophyll content relative to the control,it was also probably able to reduce the amount of contaminants in the soil by way of Phytoextraction indicated by metal uptake. The decreased THC in the soil could be as a result of Phytovolatilization and or Rhizodegradation as no oil residues were observed in any parts of the plant.
