• Landfarming bioremediation was performed over 2 years on soil heavily polluted with weathered oil and oil derivatives: 23200 mg kg super(-1) of mineral oil, 35300 mg kg super(-1) total hydrocarbons and 8.65 mg kg super(-1) of total polycyclic aromatic hydrocarbons, 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 persisted after the bioremediation treatment of the contaminated soil and the metabolites generated during this process. The data shows that in soil contaminated with weathered-hydrocarbons, the number of initially detected compounds after the bioremediation process further decreased over a 2-year period and, concurrently, several new compounds were observed at the end of experiment. Higher persistence was shown by heavier n-alkanes and branched alkanes, which could be detected over a longer period. The analysis highlighted the importance of n-alkanes, their substituted derivatives and PAHs as the most significant pollutants.
