Abstract
Persistent pollutant from industrial charges produce toxic metals that can become injurious to human health in an industrial area and therefore there is necessary for environmental monitoring in such area. This study was carried out with the aim of determining the environmental risk of cement production in Obajana, North central Nigeria. The study area lies within longitude 6024'E to 6027'E 7054' to 7056'N. A random sampling method was used in field exercise. Twenty(20) groundwater, soil and plant samples were taken and analyzed for heavy metals (Cu, Mn, Fe, Zn, cr, Pb, Ni) using atomic absorption spetrophotometry. Heavy metals in groundwater such as Pb, Mn, Zn, Ni, Cr, Cu and Fe showed (0.09mg/l, 0.02mg/l, 0.01mg/l,0.01mg/l,0.13mg/l, 0.02mg/l and 0.09mg/l) concentrations respectively. Environmental pollution indices were used to ascertain the extent and source of pollution in groundwater, soil and plant in the area. Metal pollution Index (MPI) showed that the groundwater is very lightly polluted, lightly polluted, moderately polluted but highly polluted with respect to lead that is emmited from the power plant in the factory while contamination factor (CF) and index of geo-accumulation(Igeo) showed that the soil and plant in the area are unpolluted. Continuous monitoring of groundwater, soil and plant in the area is recommended.
