Alkylated phenanthrene distributions as maturity and origin indicators in crude oils and rock extracts

Polycyclic aromatic hydrocarbon (PAH) concentrations in suspended particulate samples from the Mackenzie River delta and shelf sediments from the Beaufort Sea are higher than expected for a pristine area. Low concentrations of combustion PAHs indicate that anthropogenic inputs are low. Alkyl PAH distributions indicate that a significant component of the lower molecular weight parent (unsubstituted) PAH fraction is petrogenic. The majority of the high molecular weight PAHs, together with the petrogenic PAHs, have a principal source in the Mackenzie River. Despite the high PAH content, we consider the area still to be pristine. Although PAH concentrations are below the concentrations believed to induce toxic effects on biota, the high natural concentrations may make this region of the Arctic sensitive to additional PAHs from human activities. Key words: polycyclic aromatic hydrocarbon (PAH), Arctic, baseline, sediment, effects threshold, principal components analysis

Composition and Origins of Polycyclic Aromatic Hydrocarbons in the Mackenzie River and on the Beaufort Sea Shelf

Assessing the maturity of oil trapped in fluid inclusions using molecular geochemistry data and visually-determined fluorescence colours

Relation of the methylated aromatic hydrocarbon distribution pattern to the maturity of organic matter in ancient sediments from the Mahakam delta

Analysis of series of aromatic isomers by high resolution spectrofluorimetry and capillary gas chromatrography in HPLC fractions of crude petroleums and sedimentary rock extracts

Total-aromatics fractions from an oil shale and a coal extract were fractionated in a three-step HPLC procedure. C2-phenanthrenes in the triaromatic subfraction from the first step were tentatively identified on the basis of retention indices and GC-MS data. Successive fractionation of triaromatics on reverse-phase columns yielded 20 subfractions that were amenable to a positive identification of individual C2-phenanthrene isomers by using high resolution spectrofluorometry.
