ABSTRACT

Waste engine oil (WEO) contaminated soil has been considered as harmful to the soil and plants physiology as well. The study was carried out to evaluate the effect of waste engine oil contaminated soil on the anatomy of Setaria barbata and Digitaria horizontalis and the concentrations were 0%, 2%, 4%,7% and 10% respectively.  The experimental grasses (D. horizontalis and S. barbata) were collected from the wild fallow farmland in the university campus and the waste engine oil obtained as pooled used engine oil from heavy-duty vehicle at motor mechanic workshop in Umuahia, Abia state. The soil used in this research were sieved and homogenized with the waste engine oil. The plants were raised in buckets containing 4kg of sieved sand each at 80ml, 160ml, 280ml and 400ml. The waste engine oil was mixed to the 4kg sand in the buckets. Each treatment including the control was replicated three times (3x). The plants were allowed for six weeks. At the control, the stomata of S. barbata and D. horizontalis were clearly viewed but as the concentration increased reduction in stomata and increase in sinous epidermal cell wall were seen. Large parenchyma and intercellular air spaces was observed in the stem then the root experienced distortion in the parenchyma pith on both plants (D. horizontalis and S. barbata). This showed that at high concentration of waste engine oil contamination, the anatomic structure and arrangement of cells and tissues are affected negatively and the ability for the two experimental plants (D. horizontalis and S. barbata) to withstand this stress made them fit for phytoremediation.
