Cost-efficient and rapid assessment of pollutant behaviour in soil - decision support for the remediation of contaminated sites
Abstract
Sequential supercritical CO2-extraction will be used to characterise the behaviour of selected organic pollutants in soil. By the variation of extraction parameters such as density and temperature, pollutants will be extracted from soil according to their availability. The extraction profile generated should provide an estimate about remediation time and residual contaminant concentration for a given remediation technology. In the course of this project a series of soils contaminated with PAH and petrol hydrocarbons typically occurring with oil spills will be investigated and compared to results from microbial degradation experiments, solvent extractions, and elutriates. Finally the developed method should provide a cost-efficient and rapid decision support for risk/site managers when selecting the most appropriate remediation technology for a given contaminated site.
