This study was conducted to evaluate the Enhancement of Remediation by
Eleusine indica
through augmentation of soil with cow dung. The soil was contaminated
artificially with 50kg, 75kg and 100kg crude oil. over 8 weeks period. The study included
an assessment of the polycyclic aromatic hydrocarbons (PAHs) and heavy metal (Cd and
Pb) accumulation in soil of
Eleusine indica. More PAHs was lost from soils augmented with
cow dung than from the non-augmented soil. The heavy metals (lead) were in the
augmented soils than from the non augmented soil, while heavy metal (cadmium) shows an
insignificant amount. Significant differences were noticed between the augmented soils and
the non-augmented soil (p<0.05). The results obtained in this study show that augmenting
crude oil polluted soils with cow dung will enhance remediation and restoration of crude oil
polluted soil.
