A Toxicity Assessment Approach for Evaluation of in-Situ Bioremediation of PAH Contaminated Sediments
 |
|
| Abstract: | Polycyclic aromatic hydrocarbons (PAHs) represent a group of organic contaminants known for their prevalence and persistence in petroleum-impacted environment such as groundwater, soils and sediments. Many high molecular weight PAHs are suspected carcinogens and the existence of these PAHs in dredged sediments can result in the classification of the sediment as hazardous waste, for which appropriate treatments may be necessry prior to disposal. Unfortunately ex-situ PAH treatment is not cost effective and natural attenuation/recovery has uncertainties including possible resuspension, transport and distribution over wide areas, that can produce substantial risk to human health and to the ecosystems. The widespread contamination of sediments by PAHs has thus created a need for a cost-effective remediation process for restoration of these sediments and bioremediation is one method that may reduce the risk of sediment associated PAHs. |
