Abstract

This study therefore sought to evaluate the effect of prolonged exposure to generator fumes on selected soil microbial enzymes. Soil samples used for this study were collected from different locations in Federal University of Technology Owerri (FUTO) in Ihiagwa/North-West local government area of Imo State, Nigeria. The selected areas for this investigation were areas with high traffic and business activities. These areas were busy within the hours of 8.00 am – 5.30 pm at the close of work and business activities. Four sample points were chosen in each of the locations in order to capture concentration of pollutants within that location. The soil sample used for enzyme identification was stored in polyethylene plastic bags at a temperature below 15 oC to avoid the loss of moisture, inhibition of microbial activities and enzymatic reactions. Activities of soil microbial enzymes were assayed using standard methods. The results of this study showed increased activities of the soil microbial enzymes following exposure to generator fumes when compared with those from the control site. Overall, increases in soil microbial enzyme activities were indications of the corresponding impact of pollutants on the soil ecosystems.
