|Abstract: ||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 δ13C values (which express the ratio
of 13C to 12C) 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 δ13C values for the five n-alkanes were measured in all
three oils. Isoprenoid isotope ratios (δ13C) appeared to be least affected by
biotransformation, especially in the No.6 fuel oil. The research suggests that
the δ13C of isoprenoids such as norpristane, may be of use as source correlation
parameters. Compound-specific isotope analysis (CSIA) is a promising method for
identifying source correlation compounds in soils contaminated with heavy or
weathered petroleum w|
