The objective of this study is to compare the efficacies of powder activated carbon (PAC) and
granular activated carbon (GAC) as amendments for the immobilization of volatile
compounds in soil. Soil artificially-spiked with chlorobenzenes (CBs) was amended with
either PAC or GAC to obtain an application rate of 1%. The results showed that the
dissipation and volatilization of CBs from the amended soil significantly decreased
compared to the unamended soil. The bioavailabilities of CBs, which is expressed as
butanol extraction and earthworm accumulation, were significantly reduced in PAC and GAC
amended soils. The lower chlorinated and hence more volatile CBs experienced higher
reductions in both dissipation and bioavailability in the amended soils. The GAC and PAC
equally immobilized more volatile CBs in soil. Therefore, it could be concluded that along …
