| Long description: |
• A novel and robust ultrasonic extraction method for contaminated soils with weathered hydrocarbons has been developed and optimised during the project. The method covers the determination of total petroleum hydrocarbons (TPH) between nC8 and nC40 and sub-ranges of hydrocarbons in support of the UK regulatory framework. The method can be routinely used for measuring hydrocarbons down to 10 mg kg-1 in soil. The method has been accredited ISO17025 for TPH analysis, banding and class separation
• A diagnostic strategy tool box for ecological hazard assessment of weathered hydrocarbons has been developed during this research. The tool box highlighted the role of taking a multiple-trophic view in considering both the hazard and remediation of weathered hydrocarbons. The selected bioassay techniques should be used in combination with the chemical analysis to allow ecological relevance and a more focussed understanding of hydrocarbon transformations
• This research has developed a Level II Fugacity model comprising four phases within the soil matrix, namely: air, water, mineral soil and NAPL and has demonstrated successfully that the propensity for risk critical compounds in hydrocarbon-contaminated soils to be preferentially partitioned to the NAPL and soil phases. Fugacity approach demonstrated its suitability for applications to contaminated environments and its further refining could provide a useful tool for the exposure assessment models to generate soil guideline values and to better represent contaminant fate in multimedia systems.
• A diagnostic and risk strategy protocol for weathered hydrocarbons has been developed combining chemical, biological and ecotoxicological analysis. The protocol demonstrated that information obtained might be further exploited to assess constraints of bioremediation and most significantly helping to identify optimal remediation strategies.
• A Decision Support Tool has been developed introducing contaminated land stakeholders to the range of diagnostic methods developed during the research and the resources available to them. The tool kit is an evolving process and as information becomes available the tool is refined accordingly. New technologies and reported successes and failures enable the process to be moderated and evaluated accordingly. The tool is available at: http://www.abdn.ac.uk/remediation-dst/
