Article summary:
1. An indoor cultivation experiment was conducted to study the effect of adding 5% (m/m) activated carbon on the residual PAHs in soil.
2. The results showed that the residual amount of phenanthrene and pyrene in the soil treated with activated carbon was significantly higher than that in the control treatment, while that of benzo[b]fluoranthene was significantly lower than that in the control treatment.
3. The bioavailability of PAHs in soil treated with activated carbon decreased by 35.06%, 37.73%, 39.60% for phenanthrene, pyrene and benzo[b]fluoranthene respectively, while only 1.37% for benzo[g,h,i]perylene after one month; however, this effect weakened over time.
