Biodegradation of Polycyclic Aromatic Hydrocarbons in Crude oil-Contaminated Soil using Composted Market Waste
BADA, BS; TOWOLAWI, AT & ANYIAM, DC
Abstract
Release of crude oil and its products into the environment has resulted in many problems that are
of global concern. The objective of this study was to determine effect of Composted Market Waste (CMW) on the
degradation of Polycyclic Aromatic Hydrocarbons (PAHs) in crude oil-contaminated soil. Pot experiment was carried
out with 1 kg of soil in 7 litres perforated container contaminated with 10 % w/ w crude oil, followed by amendment
with CMW at 0, 350 and 450 g. The soil was analysed for PAH after 21 days using GC-FID. Acenaphthylene,
Acenaphthene, Phenanthrene, Benzo (g,h,i) perylene, Indeno (1,2,3-cd) perylene, Pyrene and Benzo (b) fluoranthene
were present in the crude oil-contaminated soil. Concentrations of PAHs at the end of the experiment were 188.40,
38.45 and 32.73 ppm in control, 350 and 450 g respectively. Composted market waste enhanced degradation of PAHs
in crude oil- contaminated soil.
