Bioremediation of Crude Oil-Contaminated Soil Using Poultry Chicken Manure: A Laboratory-Scale Assessment
Subject area: Science,Engineering and Technology · Area of research: Petroleum Engineering
Abstract
Crude oil contamination of soil represents a persistent environmental challenge, particularly in oil-producing regions like Nigeria's Niger Delta, where spills degrade ecosystems, agriculture, and public health. This study evaluates the efficacy of poultry chicken manure (PCM) as a cost-effective, eco-friendly bioremediation agent for crude oil-contaminated soil. In a laboratory-scale experiment, contaminated soil samples were amended with PCM at rates of 5%, 10%, and 15% (w/w) and incubated for 3 weeks under controlled conditions. Key parameters monitored included total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAHs), microbial populations, and soil physicochemical properties. Results demonstrated significant TPH degradation (75?90%) and PAH reduction (80?95%), with optimal performance at 10% PCM amendment. Microbial counts increased markedly, from 10? to 10? CFU/g for total heterotrophic bacteria and 10? to 10? CFU/g for hydrocarbon-utilizing bacteria, correlating with enhanced nutrient availability and pH stabilization. Soil fertility improved, with nutrient (N-P-K) levels rising by up to 400%. These findings underscore PCM's potential as a sustainable alternative to conventional remediation techniques, offering reduced costs (estimated at $10?50 per ton of soil) and minimal environmental disruption. This approach supports greener strategies for restoring contaminated sites in resource-limited settings.
