dc.description.abstractThe proximity of the Nigeria National Petroleum Cooperation (NNPC) Depot at Apata in Ibadan, Oyo State to human settlement in the Adebisi Layout area of Apata may lead to groundwater contamination which is the main source of potable water supply in this layout. Hence the need to assess the physicochemical status and concentrations of Potentially Toxic Elements (PTEs) in groundwater samples in this layout. The physicochemical status, as well as the concentrations of PTEs (Cd, Cr, Ni, Pb and Zn) in ten groundwater samples within the study area, were determined by standard methods and Atomic Absorption Spectrometry (AAS) respectively. The physicochemical parameters studied ranged -1 as follows: pH 6.64 - 7.38, temperature 27.2 - 29.2 °C, Total Dissolved Solids (TDS) 0.99 - 1.60 mg L -1 and Dissolved Oxygen (DO) 1.05 - 1.65 mg L . The concentrations of heavy metals in groundwater samples were in decreasing order of Cd > Ni > Zn > Cr, with concentrations ranging from 0.04 - 0.31 mg -1 -1 -1 -1 L for Cd, 0.09 - 0.67 mg L for Cr, ND - 0.04 mg L for Zn and ND - 0.16 mg L for Ni. The concentration of Pb was below the detection limit. Data from the non-carcinogenic risks showed that groundwater consumption may lead to adverse health effects and unacceptable risks to the human health of the local inhabitants, but data from the carcinogenic risks assessment indicate no cancer risk.
