Abstract

Abstract: Polycyclic aromatic hydrocarbons(PAHs) is very high in toxicity and very persistent in soil.It is,therefore,essential to study conditions for bio-remediation of benzo[a] pyrene(BaP) and dibenzo[a,h]anthracene(DBA) contaminated soils.It was found that addition of green manure or straw into the bio-pile significantly promoted the degradation of BaP and DBA;aeration from 0.05 to 0.10 m³·h^-1 did not have any significant effect on their degradation;and the addition of EM actually inhibited their degradation;however,when the addition of green manure was set at 20 g·kg^-1 and the aeration at 0.10 m³·h^-1,the BaP and DBA degradation rate was the highest,reaching up to 64.8% and 74.9%,respectively after 160 days of incubation.

Key words: PAHs, remediation, contaminated soil, bio-pile
