Landfarming bioremediation was performed over 2 years on soil heavily polluted with weathered oil and oil derivatives: 23200 mg kg-1 of mineral oil, 35300 mg kg-1 total hydrocarbons, and 8.65 mg kg-1 of total PAHs. During the experiment, mineral oil, total hydrocarbon and PAH concentrations decreased by approximately 53%, 27% and 72%, respectively. A GC/MS-Scan was used to identify the crude oil components that persist after bioremediation treatment of contaminated soil and the metabolites generated during this process. The data shows that in weathered-hydrocarbons contaminated soil, the number of initially detected compounds after the bioremediation process further decreased over a 2 year period, and at the same time several new compounds were observed at the end of experiment. Higher persistence was also shown for heavier n-alkanes and branched alkanes, which could be detected over a longer period of time. The analysis highlights the importance of n-alkanes, their substituted derivatives and polycyclic aromatic hydrocarbons as the most significant pollutants.

A bacterial strain capable of utilizing 3,6-dimethylphenanthrene (3,6-DMP) as its sole source of carbon and energy was isolated from a creosote-contaminated soil. The isolate was identified as a strain of Sphingomonas sp. and was designated strain JS1. Utilization of 3,6-DMP was demonstrated by an increase in bacterial biomass concomitant with a decrease in 3,6-DMP in a liquid mineral medium with this compound as its sole source of carbon and energy. Strain JS1 showed a high specificity in the use of the most abundant alkylderivatives of crude oils, such as alkylnaphthalenes and other alkylphenanthrenes, as the sole source of carbon and energy. It can also use several polycyclic aromatic hydrocarbons of three and four rings and their alkylated derivatives as growth substrates or transform them. The identification of several intermediate metabolites points to extensive metabolic activity, including the following: (i) aromatic ring oxidation and cleavage, (ii) methyl group oxidations, and (iii) methylenic oxidations. The metabolic actions of Sphingomonas sp. JS1 on the aromatic fraction extracted from a creosote-contaminated soil are also examined.Key words: dimethylphenanthrene, alkylated PAHs, biodegradation, Sphingomonas.

ABSTRACT Major advances have been made on analyses of petroleum hydrocarbons in oils, petroleum products and complex oil-spill-related environmental samples. This paper briefly describes how the advanced chemical fingerprinting and data interpretation techniques are used to identify the source(s) of tarballs from the coast of Vancouver Island and Northern California. Characterization of the unknown oil was achieved by not only a variety of “standard” analyses including distribution analyses of aliphatic, aromatic and biomarker hydrocarbons, but also analyses of diagnostic ratios of “source-specific marker” compounds, in particular the alkylated series of polycyclic aromatic hydrocarbons within the same alkylation isomeric groups. Results of the analysis revealed that (1) California/Oregon and British Columbia/Washington tarball samples were chemically similar, but were identified to be from two different types of bunker fuel; (2) the source of the tarball samples was neither Alaska North Slope oil nor California Monterrey Miocene oil; and (3) the spilled oil samples have been highly weathered since release, and the California samples were more heavily weathered than the British Columbia samples.
