  Investigation into occurrence and Remediation of Polychlorinated biphenyls in soil from Jos, Plateau State Nigeria was carried out. The polychlorinated biphenyls in the soil was extracted with 40ml hexane-acetone mixture (1:1) in ultrasonic bath for 30 minutes and cleaned with column chromatography packed with silica gel. The polychlorinated biphenyls were quantified using Agilent 6975 Gas chromatography Mass Spectrophotometer with the following results: PCB 18 (0.71), PCB 20 (0.37), PCB 28 (0.38), PCB 29 (0.38), PCB 44 (0.42), PCB 52 (0.66), PCB 101 (0.61), PCB 105 (0.17), PCB 137 (0.64), PCB 142 (0.33), PCB 153 (0.42), PCB 170 (0.13) and PCB 180 (0.21) all in mg/kg. Remediation with Moringa seed results in the followings; PCB 20 (0.28), PCB 28 (0.28), PCB 29 (0.28), PCB 52 (0.30), PCB 101 (0.18), PCB 143 (0.91) while the other congeners were completely removed.
