RB 10 Bioremediation of heavy hydrocarbons –reducing uncertainty in meeting risk-based targets: laboratory to field scale (PROMISE Project) (2010)This bulletin describes outputs from a LINK Bioremediation Project and focuses on weathered hydrocarbon transformation and its implications for bioremediation, analysis and risk assessment.The project developed the following: a novel and robust ultrasonic extraction method for contaminated soils with weathered hydrocarbons; a diagnostic strategy tool box for ecological hazard assessment of weathered hydrocarbons; a Level I and II Fugacity model comprising four phases within the soil matrix, namely: air, water, mineral soil and NAPL; a diagnostic and risk strategy protocol for weathered hydrocarbons, combining chemical, biological and ecotoxicological analysis; and a decision support tool.
