The Levels, distributions of mean concentrations of (PCBS) classified under persistent organic pollutants POP in soil, Maize and water samples was determined using Gas Chromatography and Mass Spectrometer (GC-MS). A range of 27 PCB congeners with low, medium and high concentration were widely distributed and detected in all the analysed samples. The results obtained showed wide distribution of PCBs with high concentration at the control sites than dump site, which made control site more sup citable and exposure to chemical hazard. This however may lead to negative impact in the environment most especially schools, communities and farmland as the results are above their threshold values found in the literatures. The PCB 8 in water sample at Epe control site (13.15 12.271) PCB 44 in water control site at Olusosun (0.012 0.016) were considered to be high in all the sites.
