Abstract
The level of poly-substituted organic biphenyl pollutants in the surrounding soils, plant and water bodies in Agbara Industrial area has been investigated and results show that the concentration of poly-substituted biphenyls were highest in the sewage and amounted to over 1.80 μg/L and closely followed by the sample from the lagoon having over 1.60 μg/L. The concentrations of the pollutants in the drainages fall within 1.20 μg/L to 1.30 μg/L. These values however show that the drainages form the route of the pollutants from neighboring industries while the lagoon and sewage form the receptacles and storage facility where they accumulate. The action limit for PCBs in sewage is 0.005 mg/L or 5.0μg/L. This shows that the sewage has PCBs level up to 36 % of the action limit. The PCBs obtained in the soils had the initial sample exceeding 5.6 x 102 μg/Kg or 0.56 mg/Kg amounting to 5.615 % of the action limit of 10 mg/Kg while the least sample had values exceeding 4.67 mg/Kg amounting to 4.7 % of the action limit. The plant samples analyzed accordingly had high values of 2.53 x 10-1 ng/Kg and lower values 1.161 x 10-1 ng/Kg amounting to 7.44 % and 4.74 % respectively of the action limit of 3.40 ng/Kg.
