  Soil and water samples from surroundings of selected Electricity Transformer installations belonging to the Jos Electricity Distribution (JED) Plc, Jos were analyzed for different congeners of polychlorinated biphenyls (PCBs) widely used as coolants. The EPA 3550 and 3510 methods were used for the sampling, preparation and extraction of the soil and water samples respectively. The extracts were cleaned up using column chromatography packed with silica gel (120 mesh). Thereafter, it was concentrated for characterization and quantification using Gas Chromatography coupled with Mass Spectroscopy Detector (GC-MSD). Fifteen (15) congeners were identified and quantified in the soil samples. The result obtained shows C52 to have the highest concentration with the value of 5.84 mg/kg. The range for the concentrations of the various congeners identified are: C18 (0.00-0.05 mg/kg), C20 (0.27-0... Read More»
