Ecodynamics of Exchangeable Cations and Anionic Pollutants of a Niger Delta River Sediment Receiving Industrial Effluents

Abstract The exchangeable cations and anionic pollutants of Okpoka-Woji River serving as a sink for effluents of industries located in the vicinity within the Trans-Amadi industrial area were carried out. Sediment samples were collected from six sampling stations located along the channel for the assessment of exchangeable cations namely calcium, magnesium, potassium, and sodium and nitrite, nitrate, ammonia, ammonium, sulphate, sulphite and phosphate. The mean values for the exchangeable cations namely calcium, magnesium, potassium and sodium ranged from 387.56 to 1775.78mg/kg; 2093.67 to 4517.38mg/kg; 134.27 to 1393.49mg/kg and 1140.87 to 8293mg/kg respectively. The mean values for nitrate, nitrite, ammonia and ammonium varied from 49.44 to 98.97mg/kg, 45.94 to 73.44mg/kg, 13.55 to 27.30mg/kg and 14.33 to 28.87mg/kg respectively. Sulphate, sulphite and phosphate mean values ranged from 1492.17 to 9389.58mg/kg, 1243.47 to 7062.25mg/kg and 3.13 to 8.01mg/kg respectively. The work showed that the river is polluted by theses parameters from the activities of industries operating in the area.
