Description
Summary:Investigation of electrical conductivity of contaminated earth is becoming increasingly relevant in geophysical sciences, where global environmental safety is a key issue. Riverbed sands were collected from the five south-western states of Nigeria, and electrical conductivity determined after samples have been contaminated with varying concentrations of petrol, cow dung, palm oil, manganese (IV) oxide, cement, cassava extract, wood ash, and washing soda. Impact of density was also studied for solid contaminant. Conductivity was largely proportional to contaminant concentration in all the samples in general. However with increase in concentrations of petrol and palm oil, decrease in electrical conductivity of samples was observed while increase in concentrations of other contaminants increased conductivity of samples. Conductivity was also largely influenced by the density of contaminated samples. At higher concentrations of contaminants, conductivity became constant especially when conductivity values of contaminants itself was achieved.
