Description
Summary:Chemical extractions have been shown to measure the biodegradable fraction of aromatic contaminants in soil; however, there is little research on the chemical prediction of aliphatic hydrocarbon degradation. The aim of this study was to investigate the potential for cyclodextrin extractions to predict hexadecane biodegradation in soil. Soils were amended with 10 or 100mgkg super(-) super(1) of a model alkane n-hexadecane and 100Bqg super(-) super(1) super(1) super(4)C-n-hexadecane. Correlations between the extents of mineralisation and extractions of the super(1) super(4)C-contaminant were determined. Solvent shake extractions and aqueous CaCl sub(2) extractions were poor predictors of hexadecane bioaccessibility. However, the novel HP-a-CD shake extraction showed close correlation (r super(2)=0.90, n=36, p
