| bioavailability of residual polycyclic aromatic hydrocarbons following enhanced natural attenuation of creosote-contaminated soil. | the impact of residual pahs (2250 +/- 71 microg total pahs g(-1)) following enhanced natural attenuation (ena) of creosote-contaminated soil (7767 +/- 1286 microg total pahs g(-1)) was assessed using a variety of ecological assays. microtox results for aqueous soil extracts indicated that there was no significant difference in ec(50) values for uncontaminated, pre- and post-remediated soil. however, in studies conducted with eisenia fetida, pah bioaccumulation was reduced by up to 6.5-fold as a ... | 2010 | 19775788 |
