Figure 2: Polycyclic Aromatic Hydrocarbon degradation profile for each bioreactor treatment. Key: BUNa (Un-amended control); BHKD (Heat killed contol); BNPK (NPK); BAUG (Bioaugumentation); BURE (Urea); BPOUT (Poultry dropping); BCD (Cow dung). BHKC showed slight difference in PAH degradation profile when compared to other treatments, though not statistically significant.
