    Persistent pollutants from industrial discharges produces toxic metals that can be injurious to human heath 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, Northcentral Nigeria. The rea lies within longitude 6⁰ 24’E to 6⁰ 27 and latitude 7⁰ 54’N to 7⁰ 56’N. A random sampling method was used in field exercise. Twenty (20) groundwater, soil and plant samples were taken and analysed for heavy metals (Cu, Mn, Fe, Zn, Cr, Pb, Ni) using atomic absorption spectrophotometry. Heavy metals in groundwater such as Mn, Zn, Ni, Cr, Cu and Fe showed (0.09 mg/l; 0.02 mg/l; 0.01 mg/l; 0.13 mg/l; 0.02 mg/l and 0.09 mg/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 the lead that is emitted from the power plant in the factory while the concentration factor (CF) and index of geo-accumulation (Igeo) showed that the soil and plant in the area are unpolluted. Continue monitoring of groundwater, soil and plant in the area is recommended.
