摘要

A preliminary evaluation of compound-specific isotope analysis (CSIA) as a novel, alternative method for identifying source correlation compounds in soils contaminated with residual heavy or weathered petroleum wastes is presented. Oil-contaminated soil microcosms were established using soil (sandy-loam, non-carbonaceous gley) amended with ballast-, crude- or No.6 fuel oil. Microcosms were periodically sampled over 256 days and delta C-13 values (which express the ratio of C-13 to C-12) determined at each time point for five n-alkanes and the isoprenoid norpristane using gas chromatography-isotope ratio mass spectrometry (GC-IRMS). Although some temporal variation was observed, no significant temporal shifts in the delta C-13 values for the five n-alkanes were measured in all three oils. Isoprenoid isotope ratios (delta C-13) appeared to be least affected by biotransformation, especially in the No.6 fuel oil. The research suggests that the delta C-13 of isoprenoids such as norpristane, may be of use as source correlation parameters. (c) 2005 Elsevier Ltd. All rights reserved.
