Concentration and Bioaccumulation of Toxic Metals and Polycyclic Aromatic Hydrocarbons in Soil and Lumbricus Terrestris in Kolo Creek, Niger Delta, Nigeria

The concentration of toxic metals and polycyclic aromatic hydrocarbons (PAHs) in soil, their bioaccumulation Lumbricus terrestris areas around Kolo Creek, Niger Delta, Nigeria were evaluated this study. 12 soil samples collected from 4 sites, while also where obtained. Toxic extracted using aqua regia quantified with a flame atomic absorption spectrophotometer. Extraction PAHs was achieved by liquid-liquid soxhlet extraction, gas chromatograph-mass spectrometer. factor (BAF) for both calculated. results obtained study showed that the all studied within respective regulatory limits soil. BAF less than 1 indicating minimal terrestris. Ʃ16 ranged 7.30 to 77.7 mg kg-1 1.10 4.75 across respectively. values individual which indicated PAH congeners either not bioaccumulated or accumulated metabolized. Hence, analysis metabolites is recommended.
