The ex situ study of vermiextraction of Acenaphthylene (AcPY), Benzo(e)pyrene (BeP) and Benzo(ghi)perylene (BP) form constructed vermiculture containing petroleum contaminated soil (8.00±0.01, 9.80±0.00 and 5.02±0.00 mg/kg respectively) and vermiaccumulation (AcPY, 1.05±0.00, BeP, 2.01±0.00 and BP, 1.73±0.00 mg/kg) by Esenia fetida squirms with mean vermiremoval efficiency of 100% while vermiconversions were AcPY, 86.88, BeP, 79.49 and BP, 65.54%. The identification and quantification of the 3 polycyclic aromatic hydrocarbons (3PAHs) were performed by GS/MD in accordance with analytical procedure of US. EPA 8270; 625. The bioengineered approach by E. fetida squirms in the vermiculture proved effective to detoxify and remove the persistent organic pollutants of the 3PAHs.
