Abstract: An ecological study of the effect of various quantities of crude oil spill soil microarthropod fauna was conducted. Three station P.Q and R were polluted with 0.5, 1.5 and 3.0 L. respectively. The control station C. was not polluted. A total of 553  microarthropod were collected for a period of 6 months. The microarthropod population collected were classified into 3: Insecta, Acari and Myriapoda which were further divided into 13 families, Soil pH, temperature moisture content and Total Hydrocarbon Content (THC) were measured.

Bioremediation has become an attractive alternative to physicochemical methods of remediation of polluted sites. White rot fungi (WRF) are increasingly being investigated and used in bioremediation, because of their ability to degrade an extremely diverse range of very persistent or toxic environmental pollutants. The white rot fungus, Pleurotus tuberregium, was examined for its ability to ameliorate crude oil polluted soil.
