| Popis: |
Raw mean levels of pyrene (pyr) and indeno(1,2,3-cd)pyrene petroleum wastewater were 8.00±0.00 and 9.20±0.03 mg/L respectively. Petroleum wastewater impacted soil gave Pyr (8.00±0.01) and Ind (9.50±0.00) mg/kg. The biased and effective nature of Eisenia fetida vermiaccumulated Pyr (6.94±0.02 mg/kg) and Ind (7.56±0.01 mg/kg), had vermiremoval efficiency of Pyr (86.75%) and Ind (82.17%). Thus, the treatment unit indicated Pyr (0.07±0.00 mg/kg) and Ind (0.00±0.00 mg/kg) for soil with petroleum wastewater sample while petroleum wastewater sample was Pyr (0.00±0.00 mg/L) and Ind (0.00±0.00) within 5 weeks detention period. Identifications and quantifications of the two polycyclic aromatic hydrocarbons (2PAHs) Pyr and Ind were carried out by GC/MD in accordance to manufacturer’s operational specifications. E. fetida squirms were proven bioremediation tools, capable to remove or detoxify the two environmental health contaminants from the contaminated pilot ecosystem. |
