Soil

Automobile workshops are known to be sources of release of hydrocarbons from spent engine oil and gasoline into the terrestrial environment where they may be accumulated by soil in fauna such as earthworms. These hydrocarbon wastes often contain benzene, toluene, ethylbenzene and xylene. This study was carried out to determine the concentration of benzene, toluene, ethylbenzene, and xylene (BTEX) in soil and earthworm from selected auto mechanic workshops from Isihor and Agbor Park areas in Benin City.

Refuse dumpsites often contain materials capable of polluting surrounding soils. In this study, the spatial distribution of metals in soils of refuse dumpsites in three urban towns (Ughelli, Sapele, Orhuwhorun) in Delta State, Nigeria were examined. Soil samples were collected from three dumpsites in the aforementioned towns at depths 0-15 cm, 15-30 cm and 30-45 cm, respectively.

Below-ground carbon dioxide (CO2) emissions occur naturally at CO2 springs, but the risk of occurrence at other sites will increase as geologic CO2 storage is implemented to help mitigate climate change. This investigation examines the effect of controlled injection of below ground CO2 emission on wheat plant and soil microbial respiration where spring wheat (triticum aestivum L.) was grown. The study involved setting up eight (8) experimental plots (each 2.5 x 2.5m) for the growth of spring wheat.
