Abstract
The rates of degradation of Aliphatic (AHs) and Polynuclear Aromatic Hydrocarbons (PAHs) in sediments of the Bonny Estuary were investigated. Degradation was enhanced by aerobic condition in the order of treatments 10000ppm>1000ppm>100ppm (AHs), 100ppm>1000ppm>10000ppm (PAHs) than in the anaerobic condition which was in the order 10000ppm>100ppm>1000ppm (AHs), 100ppm>1000ppm>10000ppm (PAHs). Rates of degradation differed over the harvest days [F(10.90)>Fcrit(4.17)] and between the oxygen conditions [F(10.92)>Fcrit(4.17)] (P<0.05). Degradation enhancements by oxygenation were by 9.85, 63.64 and 62.66% (AHs) and 2.07, 3.15 and 3.95% (PAHs) on Days 14, 28 and 42 respectively. Rate of degradation was dose-dependent and slower especially of the PAHs.
