| Summary: | This study investigated the heavy metal contents and microbial diversity of waste engine oilpolluted soil in some public and commercial centres in Benin City metropolis, Nigeria. The study was carried out in four Local Government Areas (Ikpoba Okha, Ovia North East, Egor and Oredo) within Benin Metropolis; the administrative headquarters of Edo State of Nigeria. Certain plots within the study area were selected based on the presence of waste engine oil spill on the ground, either due to activities of mechanics, parked vehicles, stationary diesel engines, or oil dump sites. However, in the present study only mechanic workshops (MW), bakeries (BK), generating plant houses (GN), as well as spare part dealer shops (SP) located within the City were selected. Field reconnaissance studies were carried to estimate the extent of pollution on surrounding soil, using the presence and absence of some flora and fauna, and developmental defects on some flora. Top soil (0 - 10 cm) was randomly collected from about 30 cm from the periphery of the spill sites and then pooled together to obtain composite samples. These were labelled appropriately, and immediately transported in polythene bags, covered with aluminium foil papers, to the laboratory for heavy metal and microbial assay.
