The present study investigated the effects of soil watering regimes on the intrinsic qualities of bioremediation of a waste engine oil-polluted soil. Five (5) kg of sun-dried top-soil was each placed into large perforated bowls and mixed thoroughly with waste engine oil (WEO) to...
Sediment samples taken from eight locations within the Owena Multi-purpose Dam in six sampling campaigns, covering the wet and dry seasons were analyzed for Pb, Cd, Cu, Cr, Ni, Fe, Mn and Zn using the atomic absorption spectroscopic method. Samples of three fish species: Clarias...

In order to make organic fertilizer more quantifiable and attractive to farmers, a pelletizing machine was fabricated locally to produce pellets from powdery fertilizer. However, concerns have been raised on the potential impacts this process could have on the quality of organic...
Aims: This study is aimed to determine the levels of some heavy metals in different species of fish and to compare the results with other standard values. Study Design: The gills, liver, stomach, kidney, bones and flesh of four common fish species (Tilapia zilli, Clarias anguill...

Two plant growing methods, namely use of soil and a floating hydroponic system, were compared in order to determine whether the response of radish to Cd, Cu, Ni and Zn was affected by the cultural system. Seed germination, plant biomass (root, shoot, hypocotyl), and heavy metal a...
Heavy metals are found naturally in the soil in small concentrations. These can be collected in bigger amounts by mining, agriculture, industry, and others. Also plants can processes these in toxicity levels and if putted into the food chain, human physiologic integrity is affect...
Sediment quality assessment are a scientific tools that synthesize information regarding the relationships between the sediment concentrations of heavy metals and any biological effects resulting from exposure to these heavy metals. A field study was conducted to determine the ph...
