(cest2017_01370) Level and impact of hydrocarbon in sediment characteristics of Imiringi oil and gas field facilities in the Niger Delta

摘要

This study investigated the level and impact ofhydrocarbon in Imirigi oil and gas field facilities in theNiger Delta. Sediment samples were collected in fourlocations viz: upstream, midstream, downstream andcontrol. The hydrocarbon content and total petroleumhydrocarbon ranged from 0.14 - 3.79mg/kg and 0.08 -2.41 mg/kg respectively. Other results supporting theimpact of hydrocarbon in Imirigi oil and gas field includepH (5.45 - 5.58), magnesium (3.57 - 4.79mg/kg),potassium (1.74 - 4.24mg/kg), conductivity (85.33 -273.33 μS/cm), chloride (15.17 - 22.53mg/kg), nitrate(1.53 - 3.20mg/kg), sulphate (5.49 - 12.59mg/kg),phosphate (1.63 - 3.56mg/kg), total organic carbon (4.54 -6.71%), total nitrogen (3.86 - 6.43%), calcium (13.57 -20.66mg/kg), sodium (6.49 - 10.68mg/kg). Analysis ofvariance showed that there was significance difference(P<0.05) in the various location for the various parametersapart from pH, magnesium and potassium. This suggeststhat the activities of oil and gas and other anthropogenicactivities are having a slight impact in sediment of surfacewater at Imirigi oil and gas facilities.
