| Abstract: | The evaluation and selection of technologies for the effective remediation of hydrocarbon-contaminated sites requires careful consideration of the waste/site/soil characteristics that determine their ultimate success. The presence of weathered hydrocarbon wastes and sub-optimal environmental conditions places technical restraints on the bioremediation of polynuclear aromatic hydrocarbon-contaminated soils. A brief overview of applicable bioremediation technologies is followed by an indepth critical evaluation of limiting factors that can influence the efficacy of biotreatment options, including waste composition, temperature, substrate, bioavailability, accompanying toxicants and soil structure. |
