In the present study, experiments were conducted to evaluate the change in bioavailability for three polycyclic aromatic hydrocarbons (PAHs) — anthracene (Ant), phenanthrene (Phe) and pyrene (Pyr) — either in normal soil extract that was spiked with PAHs (SESP) or spiked soil, after chemical calcification or biocalcification process. Results suggested that PAHs extractability in SESP (Ant: 2-4mg/l, Phe: 3-6mg/l and Pyr: 4.5-9mg/l) after chemical precipitation of carbonate were not statistically different when compared to negative controls. However in biocalcification experiment the difference was statistically significant when conducted with SESP (P = 0.0425, α = 0.10) or soil (P = 0.035, α = 0.10). Supporting experiment revealed that the presence of microbial cells and sequence of Ca2+, CO3 −2 addition was important in determining the extent in PAHs bioavailability reduction.
