Stroud, Jacqueline L. and Paton, Graeme I. and Semple, Kirk T. (2008) Linking chemical extraction to microbial degradation of C-14-hexadecane in soil. Environmental Pollution, 156 (2). pp. 474-481. ISSN 0269-7491Full text not available from this repository.
Chemical extractions have been shown to measure the biodegradable fraction of aromatic 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 100 mg kg(-1) of a model alkane n-hexadeccane and 100 Bq g(-1) C-14-n-hexadecane. correlations between the extents of mineralisation and extraction of the C-14-contaminant were determined. Solvent shake extractions and aqueous CaCl2 extractions were poor predictors of hexadecane bioaccessibility. However, the novel HP-alpha-CD shake extraction showed close correlation (r(2)=0.90, n=36, p<0.05) to the mineralisation data. This extraction technique has the potential to be used to assess the biodegradable aliphatic hydrocarbon fraction in contaminated soils. (C) 2008 Elsevier Ltd. All rights reserved.
